[BackupPC-users] Advice on creating duplicate backup server

Hi there,

I’ve been struggling with this for a little while now so I thought it about time I got some help!

We currently have a server running BackupPC v3.1.0 which has a pool of around 3TB and we’ve got to a stage where a tape backup of of the pool is taking 1-2 weeks, which isn’t effective at all. The decision was made to buy a server that is an exact duplicate of our current one and have it hosted in another building, as a 2 week old backup isn’t ideal in the event of a disaster.

I’ve got the OS (CentOS) installed on the new server and have installed BackupPC v3.1.0, but I’m having problems working out how to sync the pool with the main backup server. I managed to rsync the cpool folder without any real bother, but the pool folder is the problem, if I try an rsync it eventually dies with an ‘out of memory’ error (the server has 8GB), and a cp –a didn’t seem to work either, as the server filled up, assumedly as it’s not copying the hard links correctly?

So my query here really is am I going the right way about this? If not, what’s the best method to take so that say once a day the duplicate server gets updated.

Many Thanks
