What is "Back Up Current Transactions"?
This function creates a backup copy of your Current Transactions on a server,
USB drive, etc. It’s important to back up your Current Transactions
before extracting a pay period (and you'll be asked if you want to do it every
time you extract) because if data gets corrupted for any reason—a hard drive
crash, for instance—you’ll have another copy to work from. You'll be asked if
you want to back up your Current Transactions when you
extract your pay periods.
