#5 can't move psync.db

[Anonymous]

I've installed Psync v 2.1 on a G4/400 running OSXS 10.2.4 and I
get the following error message:
can't move psync.db at /usr/bin/psync line 221.

then it goes on to say the backup is completed and yet nothing is
backed up.

I'm attempting to back up across a LAN to a G5 with DVD burner
and creating a bootable backup of the entire drive.

Any clues?

TIA
