tar escaping into a different file system
2006-07-31 04:01:24
Finally I'm getting back on track after the tar 1.15.91-2 incremental changes.
Due to this issue and my yearly holidays, my backups are long overdue and
Amanda likes to do lots of level 0s (as expected).
I just noticed this in the mail log of last night's backup:
| /-- anakin / lev 0 FAILED [data write: Connection reset by peer]
| sendbackup: start [anakin:/ level 0]
| sendbackup: info BACKUP=/bin/tar
| sendbackup: info RECOVER_CMD=/bin/gzip -dc |/bin/tar -f... -

Since /proc is on a separate file system, tar is not supposed to enter that
directory.
Anyone seen that before? I'm using tar 1.15.91-2 and amanda 1:2.5.0p2-1 (+ my
backport of the fixes for tar 1.15.91, cfr.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=378558), on Debian
testing/unstable.
Is this another tar 1.15.91 breakage?
