Or perhaps I'm misinterpreting the error message.
The external drive is mounted ext3.
I created a symbolic link from /var/lib/BackupPC to /media/<my external HD uuid>
When I try to restart the backuppc service I get this error:
Starting BackupPC: 2013-04-29 20:37:21 Can't create a test hardlink between a
file in /var/lib/BackupPC//pc and /var/lib/BackupPC//cpool. Either these are
different file systems, or this file system doesn't support hardlinks, or these
directories don't exist, or there is a permissions problem, or the file system
is out of inodes or full. Use df, df -i, and ls -ld to check each of these
possibilities. Quitting..
I'd run out of time and decided it must be a filesystem problem and I would
look at it more tomorrow.
However...
# ls -l /var/lib/BackupPC

Hmmm... there is no user 495. Perhaps that was the backuppc user on my old
system.
Do cpool, pc etc have to be owned by backuppc?
Steve.
