Administrator Guide

– To view the parent folders of a particular folder, click Up.
• To type a directory to exempt from antivirus scanning, type a directory (for example, /folder/subfolder) in the
Folders text eld, and then click Add.
• To remove a directory from the antivirus scanning exemption list, select a directory and click Remove.
10. Click OK.
Excluding Files and Directory Paths from Scans
You can control what les and directory paths are scanned as follows:
• Extensions excluded from scan: Species le extensions (le types) to exclude from scanning, such as docx.
• Directories excluded from scan: Species directory paths to exclude from scanning, such as /tmp/logs (alternatively, folders
and sub-folders).
Viewing Antivirus Events
Events related to antivirus scanning can be viewed using Storage Manager.
1. Click the Storage view and select a FluidFS cluster.
2. Click the Summary tab. The antivirus scanning events are displayed in the Recent Events area.
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.
