As I mentioned to Les, this is not the initial transfer, but a new large
file which was created and needed to be backed up.

BackupPC copes very well with the large number of files, and normally
works well with plenty of time left over for each nightly run.

Thanks for the suggestions. The VPN is already compressed, so not much
point compressing again. What I really want is a way for Rsync, as used
by Pcbackup, not to delete the partially transfered file and pick up
where it left off on subsequent tries, just as running Rsync normally
does when you use the --partial option.
