Is Time Machine really backing up your drives?

A new report is out that suggests a fault may exist in Apple's Time Machine service, causing internal drives to be automatically and silently added to Time Machine's exclusion list, resulting in the service not backing up the data on these drives and not notifying the user of the change.

As outlined on Diglloyd's Mac Performance Guide blog, this problem appears to be situational to setups where many internal drives are being managed. To see this happen, be sure one of your internal drives is mounted and available, and then add it to the Time Machine exclusion list and restart your computer. After the system boots, reopen the Time Machine exclusion list and then unmount the drive you previously excluded.

When performing these steps, those experiencing this issue will see the drive disappear from the exclusion list as expected but then be replaced by another mounted drive in the system that is subsequently excluded from backups. This unintended addition to the exclusion list will result in this new drive's data not being backed up.

Items in this list will not be backed up, which by default includes all external drives. Internal drives should not be in this list unless explicitly added by you (click for larger view).

It is important to not confuse this behavior with Time Machine's default behavior for handing external USB and FireWire drives. Time Machine is built to exclude external drives by default, so only the
Mac's internal drives are backed up and not every USB thumbdrive you use is copied to your backups.

If indeed a bug, this issue appears to only be a problem for those with rather elaborate drive setups, with heavily partitioned multiple internal drives. In most cases Mac users have one or perhaps two internal drives on their systems that are handled by Time Machine quite well.

Additionally, this bug may be more specific to individual setups instead of being a problem experienced by all Mac users. While some readers have confirmed seeing the problem that Diglloyd outlined, others with similar setups have not seen this specific problem. Though Diglloyd claims it has been around since OS X Lion, this inconsistency makes it difficult to find a single cause of the problem. However, one possibility may lie in how Time Machine identifies drives to include or exclude.

When handling individual files and folders Time Machine will exclude by file path; however, when managing volumes it does so by using their UUIDs, which may be the source of the problem for those experiencing this bug. The UUID for a volume ought to be a unique number that is generated when it is formatted, and is based on the drive's properties, but if for some reason the UUID is blank (all zeros) or otherwise matches that of another drive (after cloning one volume to another), then while the system may still use it, services that rely on it for identifying the drive may have problems. It is possible that Time Machine could confuse two similar UUIDs in this manner, especially if multiple utilities and operating systems have been used to manage partitions on a system's internal drives.

Getting info on a volume in Disk Utility will reveal its UUID, which you can compare with those of other drives in the system to see if it is unique (click for larger view).

(Credit:
Screenshot by Topher Kessler/CNET)

To check the UUIDs of the volumes on the system, open Disk Utility followed by getting information on each mounted volume. In the window that appears you will find data and statistics on the drive, with one entry being the UUID. Compare these between your various volumes to make sure they are unique.

Additionally, this problem may be rooted in corruption in the Time Machine preferences file, which holds all of the volume configuration information for the service. Corrupt preferences is a common reason why programs and services stop working properly, and removing the preferences so they will be rebuilt from scratch is an easy and recommended remedy. To do this for Time Machine, first go to the Time Machine system preferences and make a note of the backup drives used and the list of excluded files. Screenshots are an easy way to do this.

Then open the /Macintosh HD/Library/Preferences/ folder and remove the file "com.apple.TimeMachine.plist" and restart your computer. This will cause the Time Machine service to relaunch and recreate its default preferences file. After doing this you can refer to your notes on your previous Time Machine configuration and add the destination drives and exclusion list items again accordingly.

Even if not everyone is affected by this bug, it does serve to remind us that there may be odd quirks with any backup system, so it is always best to regularly check your backup routines, and consider using multiple approaches to your backups (for example, drive cloning in addition to Time Machine). In addition to making sure your backup services are set up correctly, be sure to check the destination drive or drives themselves to make sure they are not experiencing any errors, by using Disk Utility to run a format and partition table verification.

These options are especially key as your storage setups expand and get more complex. Often people start with a single drive and then slowly add more storage and migrate their data to larger setups (both internal and external), and over time can build quite elaborate drive setups. As this happens, making sure the data gets properly managed with whatever backup approaches are being used becomes more important.

U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London

The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies. (Related: "Natural Gas Stirs Hope and Fear in Pennsylvania")

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph. (Related Quiz: "What You Don't Know About Natural Gas")

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas. (Related Interactive: "Breaking Fuel From the Rock")

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

• In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
• Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
• South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
• Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
• Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
• China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

Guilty Verdict in Lottery Winner's Murder

DeeDee Moore, the Tampa woman accused of swindling and then killing lottery winner Abraham Shakespeare, was found guilty today of first degree murder and other charges, after she declined to take the stand and the defense rested without calling a single witness.

In addition to the murder charge, Moore was also found guilty of possessing and discharging a firearm resulting in death. Prosecutors did not pursue the death penalty in the case, and Moore was sentenced to life in prison without parole.

"After trial and listening to all of this over two weeks, words that were said cool, calculated, manipulated. Abraham Shakespeare was your prey and victim. Money was the route of evil you brought to Abraham. You are sentenced to life in prison you shall not be elegible for parole," Judge Emmet Battles said.

Jurors deliberated for more than three hours Monday before delivering their verdict.

Prosecutors argued that Moore, 40, befriended Shakespeare before he vanished in April 2009 after he'd won $30 million in the Florida lottery. After Shakespeare had given away most of his money to people who simply asked for it, Moore agreed to manage the little he had left, but instead, prosecutors said, stole his winnings and killed him.

During a dramatic trial Moore has broken down in tears several times, and at one point said that she went into anaphylactic shock while in custody after taking the drug Bactrim when she was having problems with cuts on her ankles from being cuffed every day.

Early today the defense announced it would rest its case without calling any witnesses. Moore did not testify during her trial.

Dee Dee Moore Trial: Woman Accused of Murdering Lottery Winner Watch Video

"There is no witness that can say she ever admitted to doing the killing or participating as a principle in helping anyone else do the killing," Moore's defense attorney Byron Hileman said today.

In the courtroom this morning, Moore's friend, former inmate Rose Condora was accused of threatening witnesses by Tampa Judge Emmett Battles, and was thrown out of the courtroom.

Authorities say Shakespeare, 47, was shot twice in the chest by a .38-caliber pistol sometime in April 2009. He wasn't reported missing until November 2009. His body was found under a slab of cement in a backyard in January 2010.

Polk County authorities claim Moore offered someone a $200,000 house in exchange for reporting a false sighting of Shakespeare. She also allegedly sent the victim's son $5,000 in cash for his birthday, and used the victim's cellphone to send text messages purportedly from him.

Shakespeare's mother, Elizabeth Walker, also testified that Moore tried to hide that her son was missing, and said that he had AIDS.

Sentorria Butler, Shakespeare's ex-girlfriend and the mother of his child, also testified. Butler told the court last week that Moore is a divisive and manipulative woman who told her Shakespeare "ran off with the lady from the bank."

During the trial, jurors also watched a Walmart surveillance video that the prosecution said links Moore to Shakespeare's killing. The footage shows Moore making a $104 cash purchase of gloves, duct tape, plastic sheeting and other items detectives later found close to where Shakespeare's body was buried.

Jurors hearing the case also heard a rambling two-page letter that witness Greg Smith, a police informant who was a former friend of Shakespeare and supposed friend of Moore, says Moore allegedly forged while at a Comfort Inn & Suites in Lakeland, Fla.

The letter was meant to appear to be from Shakespeare, prosecutors said. They say the letter was a ruse to convince Shakespeare's mother that he was still alive. Moore attempted to cover her tracks while it was written, according to prosecutors.

During the trial, jurors had to be accompanied by a security escort into the courtroom after they told the judge Smith and Shakespeare's family and friends were making them feel uncomfortable outside the courthouse. None of the jurors had to be excused by the judge.

Female lemurs avoid the wrong love in the dark

IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.

The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).

Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

UN aid call as Philippines typhoon toll tops 600

MANILA: The United Nations is set to launch a global appeal Monday for aid for millions of Philippine typhoon victims as the death toll surged past 600, with nearly 800 people still missing.

UN Humanitarian Coordinator Luiza Carvalho will outline plans for an immediate aid package as well as long-term support for the southern region of Mindanao, hardest hit by Typhoon Bopha, UN spokeswoman Imogen Wall said.

"Five million people were affected and they need express assistance," Wall, spokeswoman for the UN Office for the Coordination of Humanitarian Affairs, told AFP.

"Their priority needs are food, water and shelter but there's also a big emphasis on helping people's livelihood," she said.

"So many farmers have lost their crops and it's such a poor area. People need to earn money immediately and agriculture has to be rehabilitated," she added.

She declined to give an estimate of the needs of the hard-hit region, the centre of both the country's banana as well as gold mining industries.

But she said a number of villages were still completely cut off and not receiving any aid, a week after the typhoon struck.

The region would need sustained assistance for at least six months, she added.

Carvalho is due to outline the aid plans at 0730 GMT in Davao city, near the area worst hit by the typhoon.

The civil defence office in Manila said 647 corpses had been recovered after landslides and floods obliterated entire communities in the typhoon's path.

A total of 780 people are still missing, including about 150 fishermen from General Santos, the country's tuna capital, who had put to sea ahead of Bopha's landfall.

Civil defence chief Benito Ramos has said many of those missing could be among the hundreds of unidentified bodies, many of them bloated beyond recognition.

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Remains of Banda Superstar Jenni Rivera's Jet Reported Found

UPDATED: Multiple reports, including one from Gerardo Ruiz Esparza, Mexico's Secretary of Communications and Transports, confirm that the remains of the private jet carrying Jenni Rivera have been found, with no survivors. Rivera, 43, was one of seven passengers.

Rivera's father, Pedro, confirmed the news of his daughter's passing to reporters stationed outside of his home in Lakewood, Calif., where several family members are gathered, including Rivera's mother Rosa and her eldest daughter Chiquis, who has still not made any statements. Rivera's father reportedly received the news via telephone from his son, singer Lupillo Rivera, who was in Mexico at the time of the jet's disappearance. "This is the first tragedy of this kind that we suffer as a family," Rivera's father told reporters on Sunday evening. "I hope people remember her as she was - someone who was straight with the world."

Celebrity reactions on Twitter have poured in since news of the disappearance of Rivera's jet, including Paulina Rubio (who was set to co-host the Mexican edition of The Voice with Rivera) William Levy, Joan Sebastian, Ricky Martin, and others.

Mexican officials have confirmed the disappearance of a private jet carrying regional Mexican music superstar Jenni Rivera that took off from the northern Mexican city of Monterrey at 3:15 a.m. local time on Sunday and fell off the radar 10 minutes (or 62 miles) after take-off.

The Learjet 25 jet, which dates back to 1969, is believed to have been carrying seven people – five passengers and two pilots. It was headed for Toluca International Aiport, located outside of Mexico City, where it was meant to arrive at 4:40 a.m. An official search for the jet was initiated at sunrise.

Rivera's publicist Arturo Rivera and her make-up artist Jacob Yebale are believed to have been on that flight. Their most recent tweets are of photos from Rivera's concert in Monterrey on Saturday night.

The Mexican American singer's most recent tweet is a re-tweet of what appears to be a fan's message.

Rivera was due in Toluca this evening for the taping of a Mexican TV show, La Voz. Televisa has canceled tonight's show given Rivera's disappearance.

Known as La Diva de la Banda and beloved by fans on both sides of the border, Rivera, 43, has had a groundbreaking career in regional Mexican music, selling some 15 million records. Among her many feats in a male-dominated genre, she made history in September 2011 when she sold out the Staples Center in Los Angeles, the first female regional Mexican artist to do so. Her reality show on mun2, I Love Jenni, is one of the network's highest rated shows. Rivera made her film debut at the 2012 Sundance Film Festival in the indie family drama Filly Brown, due in theaters in January 2013.

The Long Beach, Calif.-born singer's personal life has often called for as much attention as her career. A mother of five, Rivera had filed for divorce from baseball player Esteban Loaiza in October after two years of marriage, citing "irreconcilable differences." Soon after, rumors of an affair between Loaiza and Rivera's own daughter Chiquis surfaced, which Chiquis addressed on Twitter in October by saying, "I would NEVER do that, Ever! That's a horrible accusation."

Kenyan elephant numbers plummet by 1000 in four years

IT'S a case of up then down for Kenya's second largest population of elephants. After a promising growth spurt, the elephants are now dying faster than they are being born. The decline is being blamed on illegal poaching, driven by Asia's demand for ivory.

The Kenya Wildlife Service recently conducted a census of the Samburu/Laikipia population, the country's second largest. It found that the population lost over 1000 elephants in just four years, and now stands at 6361. Previous censuses in 1992, 1998, 2002 and 2008 had revealed a growing population, which appears to have peaked at 7415 in 2008.

Poaching is suspected. A July report by three conservation groups found that it has been on the rise across Africa since 2006. Poaching is also spreading eastwards from central Africa into countries like Kenya, says Richard Thomas of TRAFFIC in Cambridge, UK, one of the three groups that drafted the report. The July report found that more than half of all elephants found dead in Africa in 2011 had been illegally killed.

The rise in poaching appears to be driven by increasing affluence in China and Thailand, where ivory is often used to make religious sculptures and other decorations.

Organised criminal gangs have capitalised on this increased demand. "If it's worth someone's while to smuggle the ivory, they'll take the risk," Thomas says. There is evidence that gangs are moving into Kenya to hunt elephants.

China's inflation rises to 2.0 percent in November

BEIJING: China's inflation rate accelerated slightly to 2.0 percent in November, the National Bureau of Statistics said on Sunday.

It is the first increase in the consumer price index since August. Inflation stood at 1.7 percent in October.

The result compares with a median 2.1 percent forecast for November in a survey of 12 economists by Dow Jones Newswires.

Producer prices -- which measure the cost of goods as they leave factories -- declined 2.2 percent year-on-year, falling for the ninth straight month, the data showed. Producer prices fell 2.8 percent in October.

China's economy grew 7.4 percent in the third quarter until the end of September, its weakest performance in more than three years and the seventh straight quarter of slowing expansion.

But recent numbers, including manufacturing, trade and industrial output, have led to optimism among economists that the world's second biggest economy is rebounding.

China is scheduled to announce industrial production, retail sales and fixed asset investment figures for October later on Sunday.

Inflation rose 2.0 percent year-on-year in August, but fell to 1.9 per cent in September.
