Antivirus Policy
Depending on the antivirus policy, a le could be deleted immediately or made inaccessible to users and programs.
If the antivirus server or NAS cluster's default setting causes le deletion, you can only recover a previous (uninfected) le. For
example, you can recover a deleted le from a NAS container snapshot.
The antivirus policies that result only in access denial are:
• Quarantine le (default)
Quarantining a le involves the following steps:
– The le is copied to a .quarantine folder at the volume root and is accessible only by administrators.
– The le name is changed to include a string that species the date and identies the le as infected.
– File permissions are changed to permit access only by the root user.
• Prevent le access
The le remains in place, but le permissions are changed to permit access only by an administrator.
Access Infected Files
Only administrators can access infected les. Infected les can be accessed through an NFS export. However, NAS antivirus does
not support NFS exports.
To access infected les:
1. Click NAS, expand NAS Clusters and Local Containers, and then select the NAS container name.
The infected le will be quarantined or in a denied access state.
2. Create an SMB share with a directory path to the directory that contains the infected le (such as the .quarantine directory).
CAUTION: Do not enable NAS antivirus on this new SMB share.
3. Move the le to a location where you can either safely scan and disinfect the le according to the instructions provided by the
antivirus software vendor or otherwise dispose of the le.
Create a NAS Container Quota
Quotas dene how storage space on a NAS container is allocated among users and groups of users. You can create a quota for a
specic user, for each user in a group, and for all the users in a group, and you can notify those users when they cross dened
thresholds in their allocated space.
To create a quota:
1. Click NAS, expand NAS Clusters and Local Containers, and then select the NAS container name.
2. Click the Quotas tab.
3. In the Quotas panel, click Add. The Create quota dialog box opens.
4. In the Create quota dialog box, select the type of quota:
• Single user — Quota applies to a specic user.
• Each user in the group — Quota applies to each user in a group.
• Group total — Quota applies collectively to all the users in the group.
