Backup Central

Hi all

I've problem with rsnapshot (fantastic utilities...lots of thanks for
developpers).

I want snapshot a server (remotly via ssh) and I've this configuration

config_version 1.2
....
one_fs 1
snapshot_root /snapshots/myserver
....
backup root < at > myserver:/
backup root < at > myserver:/usr/local/


On my myserver It's two partition (one for / and one for /usr)

When I launch the rsnapshot everthing work for / but for /usr/local I've
every day full copy (not hard-link). Well that's expensive snapshot ;-)

Maybe I can't make backup two file-system sharing a mounting point ? Or
maybe it's some little bug ?

If it's not a bug how can I snapshot my server ?

Regards.

My guess is that when you do the backup of /, rsync is deleting everything
under usr (because that is not in the remote root filesystem, and rsync has
been told to delete anything that is not present on the remote filesystem).

If that is your problem, you could remove --delete-excluded from
rsync_long_args, and then exclude /usr from the backup of /.
#rsync_long_args --delete --numeric-ids --relative --delete-excluded
rsync_long_args --delete --numeric-ids --relative
backup root < at > myserver:/ myserver/ exclude=/usr/

Or another way you could do it is by putting the root backup into a
different sub-directory (eg: "root"), like this (assuming --relative):
backup root < at > myserver:/ myserver/root/
backup root < at > myserver:/usr/local/ myserver/

Then if the rsync of / deletes everything in myserver/root/usr, it
will not interfere with the backup in myserver/usr/local.

Note that rsnapshot 1.2.3 (and I think 1.2.2) has a problem with backing up
a remote root like that - it will end up backing up root's home directory
instead. If that was your problem, you could fix it by using "myserver:/."
instead of "myserver:/" (putting an extra dot on the end).
