Understand application backup
The Backup feature enables you to back up the applications in your account with data and restore them whenever required. ManageEngine AppCreator creates a new version of the backup file whenever you back up an application. A copy of the backup file can be downloaded after the application is backed up. You can do a one-time backup or set the frequency of backups to take place automatically at regular intervals when you don't have time to back up data manually. The backup file will be in a zip file format. It will include the deluge script file and a set of .csv files containing the application data. You can also restore the backed up application. Your application structure and data are restored from the version that you chose.
Assume a Customer Management application for a publishing house. It consists of customer contact form, customer details form, and subscription form (including associated reports). You can schedule periodic backups to run on a weekly basis. In the event of an application crash, while making some updates, you can just restore the previous week's backup, so that a great deal of the developments made from the time of its creation until the latest backup is restored. If there is a need to undo a few updates made to the application, it's not necessary to remove the updates manually. You can only restore the application to a previous date when the updates were not yet made. This feature eliminates the hassles of rework.
