Snapshot Global Settings
There are two global snapshot settings:
In the Snapshot Manager window: Click "Snapshot global settings" (the gear icon) in the
top-right corner of the Snapshot Manager window. There is one global setting:
Make snapshot directory (@Recently-Snapshot) visible: Mount a snapshot volume
as a directory of a shared folder and set the snapshot volumes to be accessed
(read-only) in File Station. The snapshot directory will appear as "@Recently-
Snapshot".
In the Storage Manager window: Click "Global Settings" (the gear icon) in the top-right
corner of the Storage Manager window, and there is one global setting:
When reaching snapshot limitation: Choose the policy to handle snapshots when the
snapshot limitation is reached. There are two choices.
o
Overwrite the oldest snapshot: When the number of snapshots reaches the
limitation (256 per LUN, 1024 total) the oldest snapshot will be deleted in order
to make space for new snapshots.
o
Stop making snapshot: When the number of snapshots reaches the limitation
(256 per LUN, 1024 total), no more new and scheduled snapshots will be taken
until existing snapshots are deleted. This option will prevent the deletion of older
snapshots without administrators’ consent.
Note:
The "When reaching snapshot limitation" setting uses the number of
snapshots, not the space used for snapshots. For more details, please refer to the
Setting Snapshot Reservation section.
Managing Previous Versions in Windows
Starting with QTS 4.2.1, snapshots can be used with the Previous Versions feature in
Windows, allowing you to instantly revert to a previous version of a file in the event of
an accident (e.g. file deletion, corruption, or accidental changes.)
To use this feature, follow these steps:
1. In Windows, connect to a shared folder on the NAS (the shared folder must be
located in a storage pool where snapshots can be taken.)
2. Take a snapshot of the storage pool where the shared folder is located.
3. In Windows, right click on a shared folder (or a file in that shared folder) in "File
Explorer" > "Properties" > "Previous Versions".
4. Select a version and choose to open, copy, or restore that version.
5. Click "OK".
