Two ideas: - Take out the disk, plug it directly to your machine via sata. Then do the dd/rsync/whatever you want to do. 300GB locally copied don't take up that long. - Start a new backuppc-installation where you copy/recreate your setup with new bigger disks. Check that all works the same as the old install. Let them run in parallel for some days. Stop the backups on the old backuppc-install but do not delete it. You can still access the backups in case you need it. Remove the old installation only when the new installation starts to deprecate full backups. Although it works, I can't really recommend using a distant nas for /var/lib/backuppc. It doesn't give you any of the "off site" advantages, because its not really off site and its always connected. Unless you stop the backuppc-process. But then you don't get the automatic backup-scheduling. Better use an internal disk (mirrored with lvm, raid or drbd) and write daily, weekly or monthly archives to a nas. You can then either schedules these archives either by cron or by hand. You can even make cron check whether the nas is present. So that you or your co-workers regularly take the nas to home. Then its off-site... One further step would be two nas used every other interval.
