Snapshot Global Settings

Setting

Description

Smart Snapshot Space Management

Enable this feature to automatically delete the oldest snapshots when the available snapshot storage space (guaranteed snapshot space plus free storage pool space) is less than 32GB. You can also choose to automatically delete the most recent snapshots.

When this feature is enabled and the snapshot retention policy is set to "Smart Versioning", the system will retain the latest snapshot of each time interval when deleting snapshots. For details, see Snapshot Retention Policy.

Important:

If QTS is unable to create 32GB of free snapshot space, it will not create any new snapshots.

Enable File Station Snapshot Directory for administrators

Enable this feature to consolidate all available snapshots into a centralized folder in File Station. You can restore files and folders from the snapshot directory by copying them into another folder.

Make snapshot directory (@Recently-Snapshot) visible in shared folder root

Enable this feature to show a read-only folder @Recently-Snapshot at the root level of each shared folder, containing all of the shared folder's snapshots. You can restore files and folders from @Recently-Snapshot by copying them into another folder.

When the number of snapshots reaches maximum

Specify the default QTS behavior after a volume, LUN, or NAS reaches its maximum number of snapshots. You can choose one of the following behaviors:

  • Overwrite the oldest snapshot when taking a new one.

  • Stop taking snapshots.

Use timezone GMT+0 for all new snapshots

Enable this feature to use the GMT+0 time zone in the file names of new snapshots. This file naming convention can simplify snapshot management especially when working with snapshots from NAS devices located in different time zones.

This setting only applies to new snapshots. Existing snapshots are not renamed.

Show hidden files in Snapshot Manager

Enable this feature to display hidden files in Snapshot Manager. This setting does not affect files inside the File Station Snapshot Directory.

Enable Windows Previous Versions

When enabled, Windows users can view and restore files from snapshots using the Previous Versions feature in Windows. You can disable this feature for individual folders by modifying the folder's properties.
