I'd be interested in hearing about what you did to improve performance,
as we've recently been forced to switch to using Seagate BkupExec to
back up our unix machines. I've got a home grown libc wrapper that fakes
out the open and read system calls to use vos dumps instead, however
this is really really slow. Even on file servers with disks that are
known to do 25 MB/sec sustained to the host, and 100 Mbit connection
through a single switch, we still only get 3-4 MB/sec vos dump rate.
Because of this, we've considered doing file level backups. What'all did
you do to make the backup complete quicker?
