How often to back up
Next to-do item is to decide when the Backup Tool should create 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:
- Importance of project's files. The more valuable the files are, the more frequently you should back them up.
- Required time to create a backup. The more time the backup takes the more rarely you can create it. You can reduce the required time significantly by using Incremental and Differential Backup Modes.
Run a manual full backup every time you're about to change the files significantly. Doing so you'll have the ability to roll-back the changes.
Run a manual full backup every time you've just completed a valuable job on the files. Doing so you'll have the ability to restore the state of the files if 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 for 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 computer(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.
