That is too bad. It would be a good feature.
Mounting the NAS could work, but unfortunately, it seems like my particular
needs aren't 100% met with BackupPC. For me, the pooling doesn't have much
benefit because of the limited number of duplicates, and the overhead of it
checking 2 million files is hampering the backup speed. I read in one of the
other threads that simply turning off pooling doesn't seem to be an option. It
is too bad, because I really like BackupPC, it has an easy to use interface,
lots of options, etc.
Thanks for your help.
