Re: BRMS and Parallel Backup

All you really need is a 3573 with dual drives and the same attachment, SCSI, fibre, or SAS depending on the TARGET machine. Often the target machine is a different hardware level. You can have a used 3573 with two LTO3 sleds fibre attached for about $3500 - $4000. Price goes up for LTO4 and LTO5 drives but the chassis stays the same. I have an LTO3 and LTO5 in mine to keep tape read compatibility back to LTO1 and write to LTO2. LTO5 can read an LTO3 tape.

wait for IBM to get us a replacement tape drive. And the length of time.

Are you talking just a replacement drive or a whole unit? For example, my
3576 holds 6 drives. Having a whole unit can be a bit expensive. On the
other hand, if you don't use a spare drive on the shelf are they subject
to stiction or other like ailments?

LOL ... Yea... Maybe I need two DR sites then with a full recovery
configuration at each !

Hmmmm, Maybe 3 would even be even better.

But seriously, I don't think it's a bad idea to have an extra tape drive
though. You can only do so much ....

By 2nd quarter 2013 my plan is to have PowerHA SystemMirror for IBMi in
place at my DR site. Then my first line of defense will be cutting over to
the mirrored system. Tape restore would become a second line of defense if
the DR server fails.
