Interesting observation John. I note that the Differential backup on my
Linux machine (molar) included 3,492 files that apparently changed since
14,136 files were backed up in the Full backup. This is just the /home
directory.
The files that were backed up are ones that had changed since the
previous Full backup. It's like the Differential backup is ignoring the
Full backup that just completed, but not the one that happened a week
before.
I suspect that there is a reasonable explanation for this since one
would not expect a differential backup to immediately follow a full
backup. Possibly the updated catalogue isn't being read or the Last Full
Backup date isn't being updated immediately. At any rate, the problem
remains that a Full backup is being performed each week.
I don't suspect anti-virus software since I'm getting the same problem
on both the Linux and Windows backups. No anti-virus software was
running on the Linux machine.
