[Veritas-bu] Write Errors
2004-05-24 10:46:07
Sounds interesting, as the server in question is a cluster node and
contacting the backup server over gig Ethernet. The rest of the machines
which seem to back up fine are running over 100meg cards.
Problem is i want max throughput from the database nodes due to the amount
of data i need to back up each night :(
Would the best way to limit bandwidth be in the bp.conf as documented?
Thanks
