BackupPC's claim to fame is its ability to de-duplicate repeated files
by hard-linking to a common pool. Since hard links can only occur on a
single file system, backups are limited to a single file system.

It's not that big a limitation if you use a modern filesystem (with
exabyte or more size potentials) plus/minus LVM to allow the
filesystem to extend across multiple physical disks.
