Estimating a restore time

I'm in the process of creating a disaster recovery plan. My boss would like an approximate restore time. We're running an 820 with 432 GHz of DSAD (45% usage). Using a 3581, an entire system back up (using option 21) takes three hours. How can I calculate restore time? All things being equal on your recovery system (same disk config, CPU config, RAM, tape drive), figure that a restore will take approximately twice as long as a backup....

However, the best way to determine this time is to perform a disaster recovery test at your hot site. It is wonderful that you are putting together a disaster recovery plan, but it won't be complete until you test it. Test it as soon a possible and then regularly from now on. I'd recommend testing your recovery plan at least once a year.
