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.
