<h4><a name="sc1"></a>1. Introducing ASUSTOR Snapshot Center</h4>
ADM now has the capability to perform volume snapshots with Snapshot Center and Btrfs. Snapshot Center makes it easier to manage, schedule, create and restore snapshots. Schedules can be set to create snapshots or be manually created at any time. Snapshots also make it incredibly easy to restore previous versions of files and can be integrated with existing iSCSI LUNs in Snapshot Center with all volume snapshots for easy browsing and restoration.
 System requirements for Volume snapshots: AS31, 32, 40, 50, 51, 52, 53, 54, 61, 62, 63, 64, 70, Drivestor Lite (AS11TL), Drivestor Gen2 (AS12), Drivestor Pro Gen2 (AS33 v2), Lockerstor, Lockerstor Gen2, Lockerstor Gen2+, Lockerstor Gen3, Lockerstor Pro, Lockerstor Pro Gen2, Flashstor, Flashstor Gen2. iSCSI LUN snapshots supported in other models.

<h4><a name="sc2"></a>2. Create Btrfs Volume</h4>
Volumes must be formatted with Btrfs to support snapshots.

<a name="sc21"></a>2.1 Initialize NAS
The options for formatting as Btrfs are found in both 1-Click Setup and Custom Setup. Enable Btrfs to ensure your volume will support snapshots.
 
<ul>
<li>Select "1-Click Setup" or "Custom Setup"</li>
</ul>

<a name="sc22"></a>2.2 Recreate Volume
Volumes formatted as ext4 cannot be converted to Btrfs. To format a volume to Btrfs, all data will need to be backed up and the volume recreated as a Btrfs volume. If recreating Volume 1, apps will need to be reinstalled and settings will also need to be backed up and imported.
 
Step 1
<ul>
<li>Recreating a volume will erase all data on that volume. Back up all important data to another storage device before continuing. ADM has a variety of options for backing up data.</li>
</ul>
ADM 5.0: 
<ul>
<li>Click [Settings] in ADM, and select [ADM Maintenance] [Settings Backup] [Export Settings] to back up system settings.</li>
</ul>

</div>
</div>
</div>
</div>
 
Step 2
<ul>
<li>After all needed data is backed up, click [Storage Manager] in ADM</li>
<li>Choose the volume that will be reformatted as Btrfs as it will need to be removed before formatting as Btrfs.</li>
</ul>

Step 3
<ul>
<li>Select Btrfs when setting up your volume in the Volume Setup Wizard and ADM will format the volume as Btrfs.</li>
<li>Copy and restore backed up data.</li>
</ul>

<h4><a name="sc3"></a>3. Introducing Snapshot Center</h4>
Snapshot Center is ADM's app for managing Btrfs and iSCSI snapshots in your NAS. View, delete, schedule and restore snapshot data with Snapshot Center. Snapshots do not take up a lot of space initially and only use more space after modifying files. A volume should not be allowed to completely fill up to capacity as this may interfere with snapshot creation. To save space, feel free to delete unneeded or unnecessary snapshots.

<ol>
<li>Once: Creates a snapshot at a specific time and date.</li>
<li>Daily: Snapshots taken every day with intervals of 5 minutes up to 12 hours.</li>
<li>Weekly: One or more days of the week can be set to create snapshots with options for daily included.</li>
</ol>
</li>
</ul>

Snapshots can be locked and retention rules can be set. Snapshot Center limits saved snapshots to 256. Upon reaching the limit, schedules can be terminated or Snapshot Center will automatically remove the oldest unlocked snapshot. When a snapshot is locked, it will not be removed automatically.</li>
</ul>
 When a volume's used capacity is greater than 95% of volume capacity, unlocked snapshots will be automatically deleted. If a volume's used capacity is greater than the upper limit after deleting all unlocked snapshots, no new snapshots will be made. (Introduced in ADM 4.2)

<ul>
<li>Remove: Removes selected snapshot. Multiple snapshots can be removed by holding Shift.</li>
</ul>
 
 Note: ADM will stop creating snapshots if a new snapshot exceeds the maximum amount of snapshots while all previous snapshots are locked. Users need to manually remove the locked snapshots and then can create snapshots again.
