Greetings,
We are ramping up our Technical Recovery Plan, and intend to use channel-
extended tape units at a remote location when performing our regular full
and incremental backups.
We use CA's VM:BACKUP for file-level backups, and will be using VM:HiDRO
to capture the system image. We're curious as to whether any other CA
customers are using the synchronous tape "twinning" feature with one loca
l
tape unit and one remote. We've been cautioned by our network folks that
the response time from the remote tape unit would be quite a limiting
factor affecting the speed of a synchronous, twinned backup.
Our other option is to simply run two backup jobs, one to the local drive
and one to the remote, but that effectively doubles the hit of the backup
jobs.
Any anecdotes or insight would be most welcome!
