Re: [Veritas-bu] General questions for everyone

Don’t try to outsmart the NetBackup scheduler. In most cases, it will do a better job of it than you can and you’ll be more supportable.

One better option would be upgrade to GigE (only 900 clients – what are you doing this weekend? J) and then reduce the multiplexing down. I suspect you’re not getting good very good write rates now.

Subject: [Veritas-bu] General questions for everyone

Say you have over 900 clients to backup from 5:00pm – 8:00am…20 LTO3 tapes drives in a library. 99% of the environment is Windows including my media servers / Master node and I am running multiplexing (20) in some cases. Right now 90% of all my jobs kick off at 5:00 on the dot. Seems that many of my jobs when they kick off will sit in a Queued status for 15 – 20 minutes at the kick-off, the active jobs will increment every few seconds. I understand I’ll have jobs queued once the multiplexing hits the threshold for number of jobs per tape, or if all my tape drives are being used. But was just wondering if I staggered my start time would help load up the tapes / writing to tape any quicker, or simply go to an active state sooner? But unfortunately I am running on a 100mb network, but it is segregated from my production network.

Suggestions?

Thanks

Dan Cruice
