[rdiff-backup-users] Bad index order during --check-destination-directory (again)

[Giorgio Moscardi]

Hi,

it happened again. Last night a backup of mine ran as usual, but it
triggered the following error:
------------------------------------------------------------------

So I went to revert the failed backup, but:

Any hints on how I can get back to a working state? I don't mind for
last night's backup data, I can safely lose that, but I want to keep the
backup history up to yesterday. Last time (see this thread:
http://lists.gnu.org/archive/html/rdiff-backup-users/2009-02/msg00115.html.
Please note that I upgraded to 1.2.8 since then.) I used the recovery
method suggested in the FAQ, but it totally corrupted my backup and I
had to start from scratch.

It it probably worth mentioning that the backup is done on a samba
share, so the "text file busy" error probably has something to do with
that and might happen from time to time.

Thanks,
Giorgio
