In one throughput test, I got about 25MB/sec over USB2 and 37MB/sec over eSATA. Same disk drive, I think it was a 1.5T seagate. Don't remember what USB bridge I used, i'm sure that matters. Might have been one of those cheap external dongles. I would imagine firewire would do about as well as eSATA, it is pretty efficient compared to USB. > > Would like some advise on the best way to backup backuppc.

All you need to do is unmount your backuppc filesystem, and dd from the raw device containing the filesystem to your new device. danno -- Dan Pritts, Sr. Systems Engineer Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224 SC09: Visit the Internet2 Booth #1355 November 14-20, 2009 Portland, Oregon Convention Center http://events.internet2.edu/2009/sc09/ ------------------------------------------------------------------------------ Come build with us!
