affected/installed dar versions: dar-2.7.12-bp156.1.4 and
dar-2.7.15-bp160.1.3 from official openSUSE repositories
openSUSE Leap 15.6 and openSUSE Leap 16.0
Hello,
dar (on some of my backups, not all) creates corrupted archives:
ls and dar -t output (dar -l same output)

everything looks fine besides these "Failed resaving uncompressed
the inode data", but the created .dar files are unusable!?
I have the same problem on 2 different computers/servers with the above
mentioned versions/distributions for two different backups (one machine
backup /root/ false, on the other backup /etc/ fails (same Failure
mode).
Never had the issue before. I created a new backup script, which runs
fine on an older install and dar-2.4.18-2.3. and deployed it after
much testing to other machines. what essentially changed from before
is compression (from gzip to bzip2) and the use of btrfs snapshots.
It happens both with -c and -A (differential to older, not-corrupted
Full-backup)
Do you have any idea? consulting search machines and chatGPT didn't
result in anything useful.
Thank you,
Paul
