As someone in an IT career, I have seen data get lost many, many times. Drives fail and they weren't backed up or the backups weren't running. Users left important files on their desktop even though they were warned the desktop isn't a safe place to store data because it doesn't reside on the file servers that are backed up. Years of family photos are stored only on an external drive and someone's niece trips on the USB cable, sending the drive flying.
Whatever the case might have been, more and more these sorts of anecdotes have been reminding me of the 8 GB of pictures, 35 GB of music, 200 GB of videos, and all the other data that I have that is either difficult to replace or entirely irreplaceable. Not all of it is truly important, but a lot is. With very large hard drives being so cheap and the very fact that I got a 1 TB external drive for Christmas, I decided that it is time to start doing backups.
That said, I don't know what program to use. I looked into the solution bundled with Windows 7: Windows Backup and Restore. Lots of people seem to hate that it isn't like ntbackup anymore and is more of an image backup program like Acronis True Image or Norton Ghost. However, with a 1 TB external, that doesn't bother me too much. The killer seems to be that the way it is programed now. It is essentially broken. It is supposed to take a full backup and then do incrementals after that, but there is an issue in how it chooses files for the incremental backups. It decides what files to back up based on the ChangeTime NTFS attribute. It turns out that on Windows 7, this attribute is updated by the Windows Media Player Network Sharing Service after every reboot or resume for any files within the Public hierarchy. In terms of size, the biggest chunk of my data is in there. You can disable this service, but then in breaks things like Windows Media Center Extenders and I use my Xbox 360 as one. So this is out.
I have a copy of Nero Back-It-Up 4. However, it doesn't support Windows 7. It supports volume shadow copies, but it rarely was able to back up from shadow copies under Vista and it doesn't even let me enable the feature on Windows 7. Instead of fixing the program, Nero has released Back-It-Up & Burn, but I have no interest in that based on the problems I had with its precursor and the way they abandoned it almost immediately after I got it (though, admittedly, I got it free with a copy of Nero 9... now I know why they had the promotion).
I see that there are a fair number of other programs out there, but I'm not sure which ones are good. Anyone have any experience backing up files or volumes on Windows 7?
