Clearly any single machine is going to have difficulty in maxing out the drive. I'd therefore like to try running backups from multiple machines to the drive simultaneously. If it does support multiplexing, what kind of options do I need in the config files? I currently have bacula talking to the drive, but I was getting 25MB/sec backing up a 10gig file of zeros (admittedly from a single SATA disk so that's not too surprising), but just 10MB/sec doing a trial backup of a home directory server over the network, from a pretty fast RAID. We get better performance from our current LTO-2 drives and Legato Networker :( Thanks. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
