Package: rdiff-backup
Version: 0.13.4-3
Severity: critical
Tags: sid
Justification: causes serious data loss
Thanks for maintaining rdiff-backup.
It's concept is great.
The main reason I'm writing is to report that, at
least on my box, rdiff-backup seems to be unable
to restore incremental backups.
I suspect that I'm doing something wrong, but,
since no one knows if they can restore data until
they try and the consequences of failing can be
severe, I decided to email you.
For example, when I type:
$ rdiff-backup --restore-as-of 3M /etc/passwd /tmp
it reports:
Traceback (most recent call last):
File "/usr/bin/rdiff-backup", line 23, in ?
rdiff_backup.Main.Main(sys.argv[1:])
File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 259,
in Main
take_action(rps)
File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 239,
in take_action
elif action == "restore-as-of": Restore(rps[0], rps[1], 1)
File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 451,
in Restore
if not restore_root_set: assert restore_set_root(src_rp)
AssertionError
However, incremental files exist:
$ ls -l /mnt/backup/rdiff-backup-data/increments/etc/passwd*
reports:
-rw-r--r-- 1 root root 259 Aug 16 2003
/mnt/backup/rdiff-backup-data/increments/etc/passwd-.2004-07-07T01:21:01-07:00.diff.gz
-rw-r--r-- 1 root root 399 Aug 16 2003
/mnt/backup/rdiff-backup-data/increments/etc/passwd.2004-07-07T01:21:01-07:00.diff.gz
Thanks,
Kingsley

Hi Kingsley,
Thanks for reporting.
You said that the command you ran was:
rdiff-backup --restore-as-of 3M /etc/passwd /tmp
I believe your problem is that rdiff-backup is interpreting
'/etc/passwd' as the location of the backup to restore. If you wanted
to restore the file '/etc/passwd' from '/mnt/backup' (which is where
you said backups were being made), you ought to use:
rdiff-backup --restore-as-of 3M /mnt/backup/etc/passwd /tmp
I'm going to mark this bug as done; let me know if I've incorrectly
interpreted your report.
Thanks,
Alec
