The trick I use (and has been discussed here, though years ago) is to set up your backuppc pool as a mirrored RAID pair of drives. Backups go to both drives, of course, automatically via the magic of RAID. When you want to rotate, you declare one drive as failed. Remove it, put it somewhere safe. Install a replacement, restart the RAID, and the synchronization just happens, again via the magic of RAID. In addition, SATA is a hot-pluggable interface, so (assuming your hardware does everything right), you can break the RAID pair, power down the drive, and replace it, all without rebooting. I do stop backuppc and unmount the pool disks while doing all of this, to ensure that the offsite disk will mount cleanly if needed someday. I have 3 or 4 in rotation, and swap them out once every several months. In my case, I use encryption on the removeable half, so I don't need to worry so much about how securely it's stored. I used to keep one in my desk drawer at work, for instance. paul =---------------------- paul fox, p...@foxharp.boston.ma.us (arlington, ma) _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
