We're looking to go to backup to disk next year when we refresh our
production environment. Initially we took a look at VTLs, but the price
was high enough to push us back to just plain disk instead. Now, we're
being told VTLs are much more affordable (so far, they still don't look
TOO affordable, but that's another discussion). Right now, we running 7.2
on Solaris, writing to SDLT320. We'll probably end up on 7.[45] by the
time we upgrade.
Anyway...
Is anyone using a VTL? If so, what are some pros/cons as compared to just
using AFT devices and managing the disks in the usual manner? We're a
moderate size environment (120-odd clients, etc.).
Also, I need to try and build a picture of just how big our overall backup
footprint is per retention period, for capacity planning purposes. I know
I can get sizes from mminfo (totalsize, sumsize, etc.) and even from the
savegroup completion reports, but is there an easier way to get an overall
total size?
Thanks.
