Best backup practices and recovering lost data.
Backup and Recovery
Tom has a computer running XP and he's having issues with the accuracy of the number of files in his folders. Leo says that it sounds like the file index is corrupted. He can rebuild the index in the control panel. Windows XP's copy utility is broken also, so Microsoft's answer to that was to offer a separate file copier called "Robocopy." He could also try refreshing the folder in the folder menu. Otherwise it's probably time to upgrade to Windows 7. He should make sure to backup his data too.
Tom has a Carbonite account and when he runs it, it really drains the battery. Leo says that could be because that initial backup will keep going and not allow the laptop to go to sleep. But once it does, it may not be as drastic. Leo also says that the battery indicator isn't exactly accurate either. It's more a general idea and Leo thinks it gets better over time.

Dave is looking for a good backup solution for both business and personal. He wants to encrypt the data and back it up. Leo says that if Dave turns on encryption on the drive, that's effective. The OS has encryption: File Vault for the Mac and BitLocker for Windows. He'll have to be sure he backs up the certificate and doesn't lose it. Third party options that work include TrueCrypt.
Red just bought a Synology NAS for the office. But now, the spotlight search on his Mac doesn't work. He has to enable and activate it through the terminal command, but even after that it takes forever to index. Leo says that NAS is network attached storage and it's great for backing up data. In Red's case, it's probably that the NAS uses a different file system than the Mac. And as such, Spotlight can't index it. While the NAS looks like a local drive, it isn't. It may also be how Red has mounted the NAS. He needs to use AFP, Apple's protocol.
Paul has a lot of movies on an external hard drive for the kids to watch, but the drive accidentally got formatted. Can he recover it? Leo says a simple erase doesn't really erase the data, it just makes the sector available for re-use. A format is more complete, though. That doesn't mean it's unrecoverable. Leo recommends Recuva. If it can't save it, nothing can. It's free, but he should make sure to get it from the original source. He should also be sure to enable the deep scan option.
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.
Joe's computer is slowing down and he'd like to buy HP's speed up program. Leo says that Joe needs to be sure he's getting it from HP and not a third party because it could be malware. Leo says even a utility from HP is just a way to sell him something he doesn't need. The best thing to do is just do an annual format and reinstall. It will refresh the drive and get rid of all the "cruft" or bit rot that builds up over time. So John should backup his data, format the hard drive, reinstall Windows, and update it completely.
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:
Eric has a RAID 5 server that has had two drives fail and he needs some data recovery services. Leo says he doesn't know if data recovery is even possible if more than one disc dies. If a large enough chunk of data was lost, there's just no way to get it back. But it will largely depend on how it failed. A controller could've gone bad, and that could be an easy fix and the data could still be there. This is why one backup isn't much of a backup.
Anthony wants to know if Carbonite and Time Machine backs up all user data or just his own? Leo says Time Machine will backup all user data, but he has to be logged in to his account to see it. Leo also thinks he can tell Carbonite to backup all seeable folders in the backup settings. So if he has admin privileges, he can do it. He'll want to go into his user folders to do it.
