Yeah I figured out in the web gui that the empty backups were "there", but
simply unbrowsable. That kind of reassures me.
I found this in my logs that might be a cause of the reason why everything
downloads from the host for incremental backups:
incr backup started back to 2009-06-26 22:53:27 (backup #0) for
directory /var/lib/backuppc/sshfsuser/
Xfer PIDs are now 30107,30106
/bin/tar: Substituting 1901-12-13 15:45 for unknown date format
`2009-06-26\\ 22:53:27'
And then I have this for all my files (this is only an example I fetched from
the logs):
./User/Mes documents/Mes images/Photo1 014.jpg
./User/Mes documents/Mes images/Photo1 015.jpg
./User/Mes documents/Mes images/Photo1 016.jpg
./User/Mes documents/Mes images/Photo1 017.jpg
