Backup Central

My backups have stopped working.

When I run rdiff-backup it starts with the following message:

Previous backup seems to have failed, regressing destination now.
Regressing to Sun May 2 00:00:01 2004

As it goes through the directory structure in the backup directory, an
error occurs each time it gets to /var/qmail/queue directory:

Warning, metadata file has entry for var/qmail/queue/mess/13/5325203,
but there are no associated files

I looked in the rdiff-backup-data directory and found two mirror files,
both of which have zero file size:

May 2 00:00 current_mirror.2004-05-02T00:00:01-04:00.data
May 3 00:00 current_mirror.2004-05-03T00:00:01-04:00.data

Apparently rdiff backup failed on May 3rd.

Looking at the error_log file for May 2nd, shows this:

UpdateError var/qmail/queue/mess/13/5325203 File changed from regular
file before signature

It looks to me like this file is referenced in the data file but it is
not physically in the backup set (I checked and it is in fact missing).

My questions are:

1. Is there a way to recover from this error without creating a new full
backup (basically starting over) ?
2. Is it a bad idea to backup the mail queue. I do at least want to
backup mail on the server.

I haven't had any feedback on previous messages. Is anyone actually
reading these?

Thanks.

I had seen the FAQ you referred to and I wasn't sure if this would work
for me or not.

I was hesitant to start removing files without first getting some
advice.

I two current_mirror files:

May 2 00:00 current_mirror.2004-05-02T00:00:01-04:00.data
May 3 00:00 current_mirror.2004-05-03T00:00:01-04:00.data

The one on May 3, has no accompanying meta_data, statistics, or error
files associated with it.

So I assume that one is serving no purpose what so ever and I can
probably safely delete it.

The one on May 2nd is the one that seems to be causing the problem, and
the meta_data file does exist for that mirror file.

So if I delete them both (leaving me with no current_mirror) will
rdiff-backup be able to function or re-create what it needs to do the
backup?

I still have some of your previous message marked as new, and I
hoped/hope to get back to them. At first glance I couldn't tell what
the problem was. It could be a bug in rdiff-backup, or some unusual
condition in your system.

I two current_mirror files:

May 2 00:00 current_mirror.2004-05-02T00:00:01-04:00.data
May 3 00:00 current_mirror.2004-05-03T00:00:01-04:00.data

The one on May 3, has no accompanying meta_data, statistics, or error
files associated with it.

So I assume that one is serving no purpose what so ever and I can
probably safely delete it.

The one on May 2nd is the one that seems to be causing the problem, and
the meta_data file does exist for that mirror file.

So if I delete them both (leaving me with no current_mirror) will
rdiff-backup be able to function or re-create what it needs to do the
backup?

You always need one current_mirror marker. It should work to delete
(only) the earlier one, as the FAQ recommends. But as the FAQ also
says, no one should be in this condition, so something has obviously
gone wrong in your case.
