Title: Flexbackup to LTO problem
Post by: waga on September 22, 2004, 06:13:56 PM

Hi all,

am having problems with my backups on a SME server v5.
I am backing up onto a LTO tape drive which I swap tapes every morning.

I used to be getting these sort of speeds:

  DUMP: Broken pipe

and the backup didn't complete.... (speeds as you may notice are approx 5-6 times slower)

I've rebooted the server and cleaned the tape heads, and i can't really think of anything else to do....
I think the LTO maybe faulty... any of you had problems similar to this?

Thanks

am accessing via SCSI,

problem was sorted tho... the problem was when the web i/f made changes to the config file, it changed the block size, so the drive was shoe shining.
