I think you need to research and understand a bit more about how BPC works in order to plan your strategy effectively. The "archive option" in backuppc is the same things as "local copies over and above the onsite backup", it was designed to allow people to take full snapshots off-site, usually using tape media. In your case the resulting huge monolithic full-set files are impractical to send over the WAN. The only way to get incremental functionality over the wire using BackupPC is to run another BPC server at the remote location on a separate schedule, and rsync is the way to go if your target hosts allow. Les is da man, follow his advice! Another option is to physically rotate your backup filesystems off-site - Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway. — Andrew Tanenbaum |
