Re: Full save to virtual tape?

In 2003 that would likely have been an LTO1. LTO2 as only released in 2003. That LTO1 was a big pokey.

Excellent point, but I don't have a great answer.

It was an external tape library that we bought in 2003. I think the tapes resembled the LTO5 we have now. If LTO existed back in 2003, it might have been whatever generation of LTO was current (but not bleeding edge).

What you left off was what tape drive were you using on that 810.

I started using virtual tape on an 810 iSeries running v5r4. At the time, the performance difference was night-and-day. I've been a believer since. That initial experience is dated and could probably use with a good reassessment.

For daily backups, we take the system into a pseudo-restricted state and backup to virtual tape. Then we bring all the subsystems back online and dupe to 1 or 2 physical tapes.


I was hoping to shorten my periodic maintenance window on the new server with virtual tape. The consensus is that that's a pipe dream.


Thanks
