Administrator Guide

Conguring Antivirus Scanning
To perform antivirus scanning, you must add an antivirus server and then enable antivirus scanning for each SMB share.
NOTE: If any of the external services are congured with IPv6 link-local addresses, the monitor will always show these
services as
Unavailable.
Managing Snapshots
Snapshots are read-only, point-in-time copies of NAS volume data. Storage administrators can restore a NAS volume from a
snapshot if needed. In addition, clients can easily retrieve les in a snapshot, without storage administrator intervention.
Snapshots use a redirect-on-write method to track NAS volume changes. That is, snapshots are based on a change set. When the
rst snapshot of a NAS volume is created, all snapshots created after the baseline snapshot contain changes from the previous
snapshot.
Various policies can be set for creating a snapshot, including when a snapshot is to be taken and how long to keep snapshots. For
example, mission-critical les with high churn rates might need to be backed up every 30 minutes, whereas archival shares might
only need to be backed up daily.
If you congure a NAS volume to use VM-consistent snapshots, each snapshot creation operation such as scheduled, manual,
replication, or NDMP automatically creates a snapshot on the VMware server. This feature enables you to restore the VMs to the
state they were in before the NAS volume snapshot was taken.
Because snapshots consume space on the NAS volume, ensure that you monitor available capacity on the NAS volume and schedule
and retain snapshots in a manner that ensures that the NAS volume always has sucient free space available for both user data and
snapshots. Also, to be informed when snapshots are consuming signicant NAS volume space, enable a snapshot consumption alert.
The FluidFS cluster automatically deletes one or more snapshots for a NAS volume in the following cases:
• If you delete a NAS volume, the FluidFS cluster deletes all of the snapshots for the NAS volume.
• If you restore a NAS volume from a snapshot, the FluidFS cluster deletes all the snapshots created after the snapshot from
which you restored the NAS volume.
Dedicated FluidFS Replay Proles
For FluidFS deployments, Storage Manager creates a dedicated FluidFS replay that is automatically assigned to FluidFS LUNs
(storage volumes). The prole setting defaults to Daily, and the retention policy is to delete after 25 hours.
Creating On-Demand Snapshots
Create a NAS volume snapshot to take an immediate point-in-time copy of the data.
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expand NAS Volumes and select a NAS volume.
4. In the NAS Volume Status panel, click the Snapshots & Clones tab.
5. In the Snapshot area, click Create.
The Create Snapshot dialog box opens.
6. In the Snapshot eld, type a name for the snapshot.
7. (Optional) Congure the remaining snapshot attributes as needed. These options are described in the online help.
• To retain the snapshot indenitely, clear the Snapshot Expiration Enabled checkbox.
• To expire the snapshot in the future, select the Snapshot Expiration Enabled checkbox and specify a day and time on
which to expire the snapshot.
8. Click OK.
