The Snapshot Retention Policy Options
A retention policy specifies the following:
*The number of hours to retain all snapshots
Every snapshot is retained for this amount of time. After this time has passed for any given snapshot, the snapshot may be retained or deleted depending on the other settings.

For example, if hourly snapshots are set to 10, then the last 10 hourly snapshots are retained. If daily snapshots are set to 0, then the hourly snapshot are deleted when the next hour starts.
*The number of daily snapshots to retain
For example, if daily snapshots are set to 10, then the last 10 daily snapshots are retained. If daily snapshots are set to 0, then the daily snapshot are deleted when the next day starts.

*The numbers of days to keep deleted files
The default retention period for deleted files is 30 days.
When portal users delete a file or a folder, either via the Web interface or via the local synchronization folder, the deleted data is moved to a recycle bin. It is then retained in the recycle bin for a number of days, defined in the retention policy of the user's assigned subscription plan. As long as files are retained, users can recover their deleted data from their Cloud Drive using a Recycle Bin feature in the end user portal interface.
