Everyone,
What ever else you do about back-ups, please take at least one copy "Off-Site" each and every night. That way in case you lose your office to a fire or flood, the main computer gets stolen, you will still have a good recent copy of your data.
As I've said before, I have bought two little Firelite Brand harddrives that are simple USB drives that I back up to every night. One stays on-site locked in a water and fire proof safe box, locked inside our drug cabinet, while the other goes home who whomever stayed latest that night in my laptop bag in a little semi-hard shelled zipper traveling case. Even with copying the entire AC folder, these copies probably only take about 1/2 to a full minute a piece to make. Every day with make a new folder, Named ACBU and that day's date (AC Back-up), so like ACBU 12-31-07. Once a month or so I cut and paste them all into a folder for that month ACBU Dec '07 let's say. It's quick and easy and now I've got a back-up of every day and one is "OFF-SITE", just in case.... Think Murphy my friends, Murphy.
I also back-up my QuickBooks to these drives any time I add serious numbers to it as well. At 80-250 Gigs there is more than enough room to hold all sorts of CCHIT. And every year or so I buy two new ones so even if they start to age out, now I'm working on newer healthy ones for my more recent data.
