Hello everyone,
I have been looking around for a solution to
backing up the BackupPC server to a "hot spare"
BackupPC server but haven't really found anything
concrete.
What I'm basically trying to do is
this:
I am currently using "dd" to make an exact
duplicate of the server's configuration on another machine (that is
also exactly the same). Once this finishes, I plan to put the drives
into the "spare" computer and place it offsite at another location that has a
direct fiber connection from the main site where the original BackupPC server
is.
What I'd like to do is change the hostname, IP,
and have the other server running without having the actual "BackupPC"
process running but installed. Then, using rsync (or some other
recommended method), I would like to have the data copied over from the main
server to the "hot spare" that is sitting at the alternate location without
BackupPC running. From my understanding and logic, if I do this, I should
be able to easily start up BackupPC if a disaster did happen and be able to
access the files just as if I was using that machine to do backups on. So,
I would like to have rsync* mirror the main server to the "hot spare" so if
files are deleted off the main server, the process would delete the files
automatically during a nightly run.
So, my question is: What is the best solution to
do this? I am assuming rsync since I've seen quite a few posts about it
(and to be sure to use -H). However, I was hoping someone would have an
entire "command" I would need to run and the best way to go about doing this
since the backup server will be assumingly still building backups
overnight. I also don't want to be retransferring unchanged files, only
the ones that have changed (just like BackupPC does with the clients
now). I've also heard someone mention "storebackup" but I'm not exactly
convinced it's any better than rsync.
Any assistance and guidance would be greatly
appreciated.
