I hope this helps.
I have an ancient AMD K6-2 running Fedora Core 1 I use just for backups. (Thanks, Fedora Legacy!) It's behind a NAT firewall to minimize security issues.
It has a pile of HDDs in it, totalling well over a terabyte. (and about to be upgrade to near 2 TB!) It's offsite from any primary hosting, and it's always on. I don't bother pulling HDD out - it's already offsite!
I use Backup Buddy http://www.effortlessis.com/backupbuddy to perform the backups. It's pretty reliable.
Anyway, if you want to "sync up" two drives periodically, I'd suggest either using software RAID 1, and re-adding the drive to a normally-broken array, (look for the software RAID howto) or using rsync. (The latter doesn't perform nearly as well as the former, but has fewer dependencies at the filesytem level)
It all depends on what you're really after...

Hi,
One of my CentOS 4 server is a repository for backups for other machines. In this server, there is a 3ware RAID card and 2 HDD for the OS + data of this server. I also have 2 drawers (each containing one 200GB hdd), connected to a promise TX2000 card. One disk will remain in the server and one will be taken outside. What would be the best strategy for syncing the hdd when I swap them?
Note: I don't want to do hot swap. No problem putting this server down once a week. It is a development server.
Regards,
Ugo
