#29 corrupted afio backup

[gianpaolo racca]

Hi, I lost recently some of my data due to some afio
corrupted archives.
I use kbackup in a cron job to backup on the filesystem.
I noticed that if I create by myself the archive with the
command found in the Logfile

cat /tmp/kbtmp6625/kbtarlist6625 | afio -o -v -T 3k
myarchive.afio

everything goes well.
If I do the backup with kbackup I obtain a (partially)
corrupted afio archive. When I try to extract it I receive a
lot of messages like

afio: "test.afio" [offset 164]: Bad magic number
afio: "test/a": May be corrupt
afio: "test.afio" [offset 253]: Apparently resynchronized
afio: "test/a.orig": Continuing
test/a.orig
test/b
afio: "test.afio" [offset 342]: Bad magic number
afio: "test/b": May be corrupt
afio: "test.afio" [offset 431]: Apparently resynchronized

I think that something goes wrong during the write_data
process since on the Logfile I see that the afio output is
passed through this.

- | write_data /backup/data.arc

I can provide my conf file if necessary.

Thank you
