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 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
