Overview
The backup retention policy defines the duration when inSync retains the backup data in a storage. You can restore this data later. To ensure that backup data is available for restore, you must define a retention policy for your inSync setup. After every backup, inSync saves a snapshot of the backup data to a storage. A snapshot is a point in time image of backup folders. It represents the state of the backup folders at the time of backup. The number of snapshots retained in a storage depends on the number of backups completed and the retention policy.
SharePoint Online backups are classified into the following three types:
- (Regular) Backup: This is the backup that occurs according to the default backup interval or the interval that you have specified for that site. For example, if the backup interval is 8 hours, inSync should create three snapshots every day.
- Weekly backup: Sunday through Saturday is considered as a week in inSync. The last successful backup of the week from a site is tagged as a weekly backup in inSync.
- Monthly backup: This is the oldest successful weekly backup of the calendar month. inSync follows the Gregorian calendar.
