Re: [rdiff-backup-users] Restore Failure with 0.13.1

[John Baker]

Thanks.  The problem was related to the famous more than one current_mirror*
file.  I deleted the earliest one and the restore operation worked.
However, when I backup now, I get this:

Previous backup seems to have failed, regressing destination now.
Traceback (most recent call last):

    self._read_eof()
  File "/usr/lib/python2.2/gzip.py", line 241, in _read_eof
    raise ValueError, "CRC check failed"
ValueError: CRC check failed

Also, I noticed the following in the rdiff-backup directory:

1) two current_mirror* files - again

2) A corrupted error log - when I try to unzip I get this:

gunzip: error_log.2003-10-30T03:10:43-05:00.data.gz: unexpected end of file

3) A  mirror_metadata with the correct date, but very small size - and the
next to last one is also very small: 109 and 99 bytes, respectively.

4) No session_statitstics file with the correct date

Do I need to delete all current_mirror* files as well as these (apparently)
incorrect files?

Thanks again,

John Baker

Those EA/ACL messages are a normal part of rdiff-backup's
initialization for 0.13.x; it is just trying to figure out what
capabilities your system has.  Are you sure the last backup was
successful?  rdiff-backup seems to think the last backup failed.  If
you 'ls /mnt/syncback/laser/rdiff-backup-data/current_mirror*' you can
see what the last successful and failed backups are.

Also you should upgrade to 0.13.3 and/or 0.12.5.
