Because of the pool model that BackupPC uses for storage, there are only
two useful methods for using two different external drives:

1. Use RAID and remove one member periodically, to take offsite. This is
best done with 3 drives, actually.

2. Use the external drives as a target for ArchiveHost, and dump occasional
tarballs of each host to them. This is OK for emergency restore but won't
give you a working BackupPC server if you want that.
