Yep, we actually have two backup servers with two tape libraries to make
two copies in parallel to reduce backup time. I didn't know it could
read the tape back automatically after writing each one for
verification; which directive in the config does that?
The data will be archived conceivably for 15+ years. Although by that
point I suspect we'll refresh our whole archive plan again because of
LTO-5 shelf life limitations. ;)
This archive strategy is for DR only - we don't plan on doing restores
at all for daily stuff. If we are restoring for any reason, something
went horribly wrong...
cheers,
erich
