Hi Luc!
You are talking about full volumes restore. Are planning to use the LTO
library for your copy pool? If so, LTO is very usable. Since a volume
restore is typically a streaming process, your volume restores will be quite
fast. LTO for a primary tape pool will be quite a different story. Indeed
the LTO start/stop characteristics are something to take in consideration.
Data on a 100 GB. volume can (and will) be scattered across the tape, so
when you are restoring a lot of data, you will see long seek times. We
choose for 3590 over LTO for this reason.
Kindest regards,
Eric van Loon
