Gene replaced a network drive on RAID 1 and when it rebuilt the RAID, it made all the drives blank! Leo says that RAID 1 (mirrored) is designed to write the same data to all drives and when one fails, it can rebuild the RAID from the other drives. Leo thinks that during the rebuild of the RAID, the drives were erased. It's not the same as partitioning and setting up, and it may not be recoverable. Leo doesn't think it's a good idea to run BIOS RAID. It's not a good choice and RAID is never a substitute for backing up. He should also make sure he replaced the correct drive.
backup and recovery
Richard is trying to back up about 300GB of photographs and videos. He's using Dropbox and it's expensive. He's also tried Carbonite, but it takes too long. Leo says that's because his upload bandwidth is really slow. Amazon has a more affordable option called Glacier. It costs pennies per GB, but it's cheap because he won't have access to it immediately.
Michael has a ton of IDX files of his images. Are they safe to delete? Leo says yes, generally. It'll make searching more of a challenge, but it won't endanger the images at all. Leo says that he imports all the images to Lightroom, then he'll sync to two external hard drives. Then he takes that second hard drive to work and swaps it out every other week. That way he always has an off-site backup.
To sync his files, he can use one of the following programs:
Tom bought an iMac and a GTech RAID drive, but he realized it runs RAID 0. Leo says RAID 0 means it has two discs linked for performance and speed. It's also known as "scary RAID" because it's twice as likely to fail. If he's using it just for basic backup, then it's fine. Drobo does a simulated RAID 5, but Leo isn't sure Tom needs all that.
Jim had a hard drive crash and now that he's restored his data, his file sharing is horribly slow. Leo says that could be due to a problem with the file sharing servers, but if they're working OK with other computers, it may be a bad restore. Leo says it could also be a security issue in Windows or even the router itself. Jim should try bypassing the router to see if it works better. If so, a reset of the router may fix the issue.
Ben has been following Leo's advice of 3-2-1 backup: Three backups, two different forms of media, and one off site. He uses IBM's Tivoli and backs up to an external hard drive, which he keeps in his car. He's been looking at Carbonite and CrashPlan's Code 42 as alternatives. Leo says it's interesting that Crashplan will let him send a hard drive to them and it's nice that it's free to use as well. Leo says that a lot of options are out there with similar services, including RSync and JungleDisk.
Lorraine is wiping her hard drive and reinstalling, and is worried that if she doesn't partition her hard drive correctly, a virus could survive formatting. Leo says no, that was an urban legend that has since been debunked. There have been cases of viruses that could hide in the BIOS or in the memory of a video card or printer, but Leo's never seen it happen in real life. So there's no real worry.
Hamit's Western Digital MyBook external hard drive crashed after his toddler got a hold of it. It makes a terrible noise now and he can't access it. Leo says the read head or disc arm has bent or broken. Sometimes it's possible to get a last use out of it by freezing the drive for a few hours. Wrap it in plastic wrap first. But that's a last ditch hail mary.
Tony is having issues backing up with Super Duper with his iMac. He keeps getting permissions errors. Leo says that for some reason, some drives can become read only out of nowhere. So he will have to change it back. Tony says when he schedules a backup, even though it's locked, he gets the same error. Leo says the issue may be in the settings in Super Duper.
Paul's computer is running Carbonite and after a power outage the D drive of his computer can't be recognized and it won't backup. Leo says that Carbonite doesn't backup a second drive by default. So he'll have to go into the settings to enable it. The drive does spin up, but it just can't be recognized. Leo says that software can recover the data, but it could be that the board got fried. Fortunately, Paul had a guy that did just that and they've been able to read some of the data. Drivesavers can recover all the data, but it isn't cheap.
