-You can request to have snapshots set up for your data directories. A snapshot is a point-in-time, read-only copy of the data in your directory, which only stores changed blocks of data in order to be more space-efficient. A snapshot rule specifies the schedule on which to take the snapshots and how many to save. You can have multiple rules for your data. This allows you to restore old versions of a file or a whole directory in case of accidental deletion or other unwanted changes. By default, there is only one snapshot being saved (taken each night at 11:00 PM).
