Overwrite or Append on differential Backups?
Posted on 2006-05-10
I am using Microsoft Backup to backup the Documents and Settings folder and an application folder to an NAS drive. I created a baseline backup using the Normal method and then set a "Differential backup" to a different file name telling it to overwrite each time.
That seems to be working but I got to thinking....
What if there are files that change less often than the backups. If I have a file that gets backed up on the differential for say three or four nights, and then doesn't change for a few days. Does using the overwrite option mean that the file in question would not be backed up?
What is the best way to provide a good backup without creating a bunch of little files that I would need to restore individually in the event of a failure?
