So I take it that this is a single unique copy of every file regardless of
host and permissions/timestamps.

Yes, I am always able to restore backed up files without any issues so the
backups are fine. However, if I was to move the cpool (currently on root
partition) to the md0 device, I understand that the old backups will not be
affected and all new backups should be linked successfully. The old backups
will gradually expire away leaving more recent backups with hardlinked files
in the pool; this will clear the server of duplicate data...is this correct?

Why would it matter that cpool is on a different filesystem since
backupPC_link uses pool, which is on the same filesystem?

I would be grateful if you could give me a clearer definition for 'hardlink'
to clarify backupPC's operation in my head.

Many thanks in advance for your patience.
