Last thing on this and I'll shut up.<br><br>No matter what the back up tool chain being used, spend some time at least bi-monthly doing a restore just to keep in practice. I can count the number of times a failure requiring file recovery was more relaxed than "OH MY GOD GET THAT DIRECTORY RECOVERED FASTER THAN THE ELECTRONS CAN MOVE IN THE WIRES!!!!" Yeah. Exactly zero. That's a skill to pull out that just screams "I am god and I will be getting a pay raise starting tomorrow".
