I know, you probably laughed at the topic as you read it because you're probably thinking like I am, that no it can't. I just don't get it though. I've changed from an LTO2 Dell internal tape drive to a Quantum Superloader3 LTO3. During this I've rearranged data and excluded some directories that were old and no longer in use (had dates of 2005 or older since last accessed). Now all of a sudden our incremental backups are roughly 20gb where they used to be 150gb.
I'm using backup exec 10. The LTO2 drive did not offer hardware compression. This really has me baffled. Now to add to it, the ~20gb backups have all been successful. The ~150gb usually had errors. One more difference to add to it, I'm now backing up a remote server also, which should add ~750mb.
I've double and triple checked that I'm backing up the necessary data, I just don't know where my extra 100gb went. Is it possible that if I had the 100gb excluded somehow in the full backups, that when it did the incremental backups, that it was backing up the files that were excluded for the full?
For what it's worth, I created new backup jobs for the incremental and full backups after getting the new drive and tapes. Again though, I'm comparing the incremental now to the incremental prior and I should be backing more, not less.
