Not directly since you use the drive as a NAS, therefore you access it
via some network protocol. Does it support NFS? If so, try using that
and perform the above test.

A not-so-nice solution would be to create an x GB file and format that
with whatever unix filesystem you like.

It would work roughly like this (for a 10 GB volume):

dd if=/dev/zero of=/backups/backuppc-volume bs=1M count=10240

mke2fs -m 1 -j /backups/backuppc-volume

mount -o loop,noatima,nodiratime /backups/backuppc-volume /var/lib/backuppc

If you run out of space on the volume later, you may resize it by
growing the file first (be careful!), then resizing the file system.

I suppose, performance is not an issue for you - it may be pretty
slow...

I wonder how you managed to do backups the first time, though... you
only upgraded your server? Then there must have been a way to create
links or BackupPC would have complained a lot.

HTH,

Tino.
