rsnapshot problem

Hello. Anyone using rsnapshot for backups? I posted this
question on the 
rsnapshot list, but haven't gotten any response. Figured I'd
give it a 
shot here.

I'm running rsnapshot 1.29 on a gentoo box, backing up a
remote gentoo
server. I recently moved my server to a new machine. After
switching the
domain name to point at the new machine, I found that files
and
directories from the old machine are still in my daily.0
backup each
morning. They are mixed with the new files and directories.

My rsync_long_args are:

rsync_long_args --delete --numeric-ids --relative 
--delete-excluded --ignore-errors


and I see these args in the log.

The backup does finish with warnings, but it almost always
does... it's
hard to backup a mail directory tree without something
changing! But,
ignore_errors is supposed to override that and delete anyway
right?

Hoping someone can help because it looks like my old and new
file
systems will remain intermingled forever at this rate...
effectively
making the backup useless (or at least a major pain to
restore).

I was thinking about deleting everything under the server's
directory in
daily.0. That should pull everything fresh right? Sucks to
have to pull
all the files again, but I'm not seeing any other way right
now.

Thanks,

Ben

I would suggest either using a different value for
snapshot_root in 
your rsnapshot.conf, or a new backup entry with a different 
destination.  

I am doing something similar on a newly setup gentoo server,
and have 
the snapshot for each remote system sent to a separate
directory:

(from rsnapshot.conf)
backup  roothotdog:/home/  hotdog/
+rsync_long_args=--bwlimit=6000
...
backup  rootcheddar:/home/ cheddar/
+rsync_long_args=--bwlimit=6000                             
                                    
...
backup  rootbatboy:/home/  batboy/
+rsync_long_args=--bwlimit=6000                             
                                            

This results in the following directory layout:

pickles portage # ls -l /snapshots/daily.0/
drwxr-xr-x 12 root root  4096 Oct 14 17:08 batboy
drwxr-xr-x 12 root root  4096 Oct 12 03:59 cheddar
drwxr-xr-x 13 root root  4096 Oct 11 19:56 hotdog
drwxr-xr-x 11 root root  4096 Oct 11 16:22 localhost

Those look fairly standard.

I don't see any way around that either.

Thanks Chris! After thinking about it, it seems best to just
delete a 
whole day and make sure I'm fresh. Don't want to add another
host, cuz 
it's really the same host... the old one is going away.
Thanks for your 
thoughts.
