That would be a start.
Putting everything on ONE flash drive isn't a great idea either, IMO. (all the eggs in one basket theory) Here are some scenarios to explain why I think so:
a) Let's imagine you forget to remove it one night, and then a lightning storm hits a pole miles away. The power surge would likely fry your computer, as well as the only backup you have. (because it would still be connected to the computer, it might get the same ZAP) Having more than one forces you to switch them out, so they're not accidentally left in the machine.
b) Your computer gets hit with a destructive virus that erases both the POS AND the contents of the flash drive. This happens in seconds.
c) A disgruntled employee could take the only chip and delete your records.
d) A break-in, where they take the computer and your only backup.
I'm not saying any of this will happen, but it could! It's worth of consideration, imo. The flash drives are extremely inexpensive, and easy to use.
We keep our daily backups (a rotation of 6 flash drives for each day of the week that we are open) on site. They have each day of the week written on them, and this forces us to change them daily.
Every Saturday, I upload the full lifesaver and accounting folders to the home pc (with remote control software).
At the first of the month, we also burn a CDR (about a nickle) with the pos folder, and all word/excel/accounting documents. That goes home as well, and goes in a fireproof safe.
Maybe i'm too careful? ha
