This could be a most valuable speedup for the initial backup of remote hosts. Currently, your choices are to do a painfully slow (or even impossibly slow) first backup over a WAN link, or physically move the server to the remote location for the first full backup. This is usually difficult, and often prevents the other backups the server has to do from working as well. The way we currently avoid this is to copy all of the remote server's data to a removable hard drive, move the hard drive to a computer on the backup server's network and create a host to back it up. Once that backup is complete, we change BackupPC's host configuration to point to the real server. The other way would be to have some sort of way to transfer a host's pool and configuration from one server to another. Then I could use a second BackupPC server to back up at the remote location, then move the pool from my portable BackupPC server to the remote backup server. I would strongly prefer the second solution: the ability to move a single host from one server to another would be *tremendous*. It would make replacing and load balancing backup servers much easier. When you're trying to build a solution that will function for long-term online archival storage (we're targeting 7 *years*), the ability to move hosts from one system to another (to divide the load on a single server, to migrate decommissioned hosts to secondary backup servers, to adjust space imbalances among servers or all kinds of other reasons) is *very* attractive. But I would assuming that moving just one host out of the pool is going to be harder than migrating the entire pool to a new host, and we already know how difficult doing *that* is... So I'm not holding my breath. I wonder if I'm just trying to push BackupPC beyond what it is designed to do?
