Next to-do item is to decide when the ABE should create the next backup of a project and if it should use a schedule.
As other steps, choosing the frequency of backups creation depends of several aspects:
You can reduce the required time significantly by switching the Backup Mode for the project.
Try to create a backup before you're going to change the files and after you finish a valuable job on the files. Doing so you'll have the ability to restore the state of the files if the made changes and the further changes appear to be wrong.
Use the scheduled backup creation to be sure you won't forget to protect your data. Try to find a time frame to create backups when your PC or network is being used minimally. If your data tend to be modified periodically, set the backup creation time to near the end of a day or in the night for the case your PS(s) are working overnight.
If you have no large enough time frame to create a backup at once, consider separating the project to smaller sub-projects to schedule them individually. However, don't forget the data integrity. If you back up a database, you have to include all database files to a single project. Otherwise, restoring fragments of the database can cause a corruption of integrity.
