I have the same problem with a G4/500 (single processor). Dantz tech
support suggested I turn on link encryption (to slow down the
backup). That didn't help. They then suggested it was the fault of
a router. I moved the G4 to various ports on my Asante FriendlyNet
8+2 to no effect. I tried both 10Mbps ports and 100 Mbps ports, both
half and full duplex. No effect. Tried a 10Mbps hub instead of the
Asante switch. No effect. I switched Retrospect host machines. No
effect. I've tried various backup devices (VXA, DDS, CD-RW), no
Software is Mac OS 9.0.4, everything up-to-date, and Retrospect 4.3.
I don't have this problem with any of the other 9 machines I back up,
and this machine is the only G4.
I'm backing up a 27MB internal hard drive on this machine, divided
into 4 partitions, roughly sized at (usable space) 2MB, 8MB, 13.5MB,
and 2MB. When doing a full backup, the failure usually occurs on the
By running 3 or 4 incrementals after a full backup, I can usually get
through the entire drive. Most incremental backups after that are
usually small enough to success, but not always.
