Is there any reason whey File::RsyncP ignores the --partial option and
the --partial-dir option?
The problem is that I am trying to remote backup over a 256K VPN.
Everything is working fine ( as is the local backup) except when a large
file was created and Rsync could not transfer it within the time out
period. The very frustrating thing is that despite spending 6 hours
transferring most of the file, the partially transfered file was
deleted, and I was left with nothing on the remote computer. This cycle
then repeats it self, wasting vast amounts of time without actually
getting anywhere.
When I was just doing a simple Rsync backup, if Rsync did not complete
the transfer of file for any reason, it would keep what was transfered,
and then resume from that point next time. This at least meant that
eventually even huge files would be transfered.
If File::RsyncP could keep the partial transfer in its partial-dir
directory, even if BackupPC didn't want to know about the partially
transferred file, at least next attempt File::RsyncP could pick up from
where it left off.
Regards
David
