If you're looking for information about how to set up a batch file which archives your complete OOTP database on your harddisk drive, have a look at this thread:

Some notes about backup strategies
Why should you make a backup?
1.) OOTP, the operating systems (Windows or Mac OS), or some hardware devices could make a mistake when writing the .dat files. This is done every time when you "save the game". A .dat file with only a single wrong byte might make the database "unreadable"! So you should always have a fresh copy of the .dat files somewhere.
2.) The harddisk drive might break. It might happen tomorrow when you start your computer - nothing happens. Drive broken. You'll never get any files back from that drive. I've seen adults crying in those situations. Only a backup on another physical drive can help here. I.e. if your game is on C:, don't make your backups on drive D:, if C: and D: are on the same ohysical drive. A good idea is to make backups on CD-R or CD-RW.
3.) The computer might get lost due to high voltage, fire, theft or whatever. In that case only a backup made on an external device or disk will help. For example on a CD-R or CD-RW which if possible is not stored right next to the computer.
