Home - once a week to external hard drive + once a month to CD
Work - every ten min from PC to on-site server, every hour from on-site server to off-site server, once a week from off-site server to off-site tape.
C: (system files partition) scanned and defragged then an ATI image once a week to an external HD.F: (Data partition) Mirror image daily to second (removable) HD using Freefilesynch.Once a month: Clone (ATI) whole Primary drive to another removable HD kept elsewhere.
This is like when people ask my how my Christmas shopping is going - I swallow something hard and jagged. I back up only very occasionally, to an external hard drive. And this makes me a bad PC Advisor editor.
