You can use the following script to save automated backup copies of a FileMaker Pro Advanced database.
This script saves a copy of your database on the fifth close and every fifth close thereafter. To make the script work, you need to define a global field called Count Field in one of the tables in your database. If you do not define a global number field, FileMaker Pro Advanced may increment a different record each time you close the application. You should define this script in all solution files that require backups.
