Best backup practices and recovering lost data.
Backup and Recovery
Tristen wants to know how to backup his computer so that he has a copy locally. Leo says in the old days, we would divide backup into online, nearline, and offline backups. Online backup would be a hard drive connected to the computer that is synchronizing with data directories. So he'd have a copy on the computer and on the external drive. Nearline backup would be if the drive were put up on a shelf, and disconnected from the computer. Offline backup would be off in the cloud or at a different location entirely. It's best to use all three methods and keep multiple copies.
Martinio can't see his external hard drive on his computer when he boots up. What software can he use to fix it? Leo says first he'll have to be able to see the drive to fix it. If he can't see it, then there's a hardware issue. It's a very expensive proposition to get the data off. DriveSavers will be able to do it, but it's very expensive.
Marnie is having issues backing up her folders with Carbonite. It says it can't back up because folders are being synced to DropBox. Leo says that's likely true, and that both are competing for the same files to back up. It may be that Carbonite has to wait until Dropbox syncs before it backs up. Leo says she can stop DropBox, uninstall it, and then reinstall it. That could make it much easier to work with.

Gloria took her computer in to be fixed and they wiped her hard drive. Leo says that when working to diagnose a computer's problem, they have to get the computer to a so called "known state," and that usually means wiping the drive and then restoring it to a factory setting. That way they can separate software and hardware issues. So it's important to backup the hard drive, and even create an image that she could restore before sending it in. She could maybe use Piriform's Recuva to get her data back. It's free to try.
Adam is thinking of making an image of his hard drive using SuperDuper, then putting it on an external hard drive and boot from it on another computer. Leo says he can do it, but the problem is he'd be using the operating system from different hardware. It could actually work, though, so he can attempt it.
Richard had Seagate Lyve, which would enable him to backup all of his photos to a Seagate hard drive or its Lyve unit. Then Seagate shut it down in December. Leo has moved to Synology and it works great. It even has a photo station program that does exactly the same thing as Seagate Lyve. There is even an Evernote server. It's not cheap, though. A good open source option is FreeNAS.
Doug is confused how iTunes works with backups. What is the "other" section of his iPad? Leo says that "other" in his iPad is cache files and other stuff that can't be deleted unless he does a restore. The trouble is that a lot of stuff gets saved there and it can build up over time. Leo recommends backing up his device, then erasing it and restoring it. It will then remove all those temp files. This is really the only way to do it.
Larry is frustrated that he can't backup his music to the cloud through iTunes anymore. Is there a way around that? Leo says that any backup he uses that isn't Apple can backup his iTunes Backup.
Don wants to know if imaging is the way he should be backing up. Leo says that imaging is good for creating a version of his computer that is frozen in time, so he can just reload it. After that, he should be making incremental backups of his data. Leo advises three backups, on two different formats, with one off site. And if he has versioning, that's even better.
