Using rdiff-backup 2.2.2 on Windows 10 Pro 22H2, I have a scheduled task that
runs my system backup PowerShell script at 2 AM every morning. The script runs
rdiff-backup several times to backup several different directories. A few days
ago one of the backups failed because the NAS volume containing targetdir
filled up. I took some remedial steps that didn't help, but at this point I
don't remember exactly what I did. I do know that this first thing I tried,
not thinking very careful, and realizing that I had recently created some large
files in sourcedir that I didn't need any more, I deleted those files and tried
doing a backup running rdiff-backup manually (incorrectly thinking rdiff-backup
would remove some files from targetdir). Of course since rdiff-backup is
creating incremental backups, and targetdir was still full, that backup failed
too. At some point I increased the size of the NAS volume, and here is where
my memory is failing me. I probably tried running rdiff-backup manually again.
Either then, or shortly thereafter, I started getting "regressing destination"
and then rdiff-backup failing whenever I tried to backup or verify, so I
attempted to follow the instructions in FAQ item 15. I did some other
troubleshooting that I don't remember, but the backups are still failing.
Now, running "rdiff-backup.exe backup --print-statistics ..." doesn't print
the expected statistics (so I assume it didn't backup anything) and produces
the following output:

and ending with the line:

Any suggestions for how to get my backups (and verifies) working again?
thanks,
Peter
