• Access

Specifies the action to be taken if the specified size limit is exceeded.

Type

File types that you want scanned or ignored by the antivirus software. For each file type, specify its value in the List field and then click the Add button.

• File Types Included - Types of files to be scanned by the antivirus software, specified as a 1-to-4 character file extension. If no types are listed, all types are scanned. If any types are listed, only the listed types are scanned. File types are case insensitive, and support * and ? wildcard matching.

Note: If a file type is listed as both included and excluded, it is excluded.

• File Types Excluded - Types of files to be ignored by the antivirus software, specified as a 1-to-4 character file extension. File types are case insensitive, and support * and ? wildcard matching.

Volume

Select the file volume you want to mirror. This field is editable only if the window is in Add mode.

Mirror Host

Name of the server that hosts the mirrored file volume. This field is editable only if the window is in Add mode.

IP Address

Internet Protocol (IP) address to be used for the mirror connection. It is recommended that you use a private network link for mirroring (a link that is not accessible to other devices in the network).

Alternative IP Address

(Optional) IP address that will be used to maintain the mirror in the event that the first IP address becomes unavailable.

Password

Enter the system administrator password of the remote host.

Mirror Buffer Size (MB)

Available only if the window is in Add mode. Size of the mirror buffer, in megabytes (MB). The mirror buffer stores file-system write transactions while they are being transferred to the mirror host server. The size of the mirror buffer depends on a variety of factors, but it must be at least 100 MB and must be at least several gigabytes in size. You might want to create a mirror buffer that is approximately 10% of the size of the mirrored file volume. The size you specify is more a function of the write activity to the source file volume than it is of the file volume size. It is important to note that the file volume free space on the active server will be reduced by the allocation size of the mirror buffer.

Click and drag this icon to move the threshold value along the scale. As you move the icon, the threshold value that is displayed on the right is updated.

Mirroring Buffer Threshold 1 (%)

The percentage of mirror buffer usage that triggers the first alert. The default value is 70%. This means that when the mirror buffer is 70% full, an alert will be issued.

Mirroring Buffer Threshold 2 (%)

The percentage of mirror buffer usage that triggers the second alert. The default value is 80%.

Mirroring Buffer Threshold 3 (%)

The percentage of mirror buffer usage that triggers the third alert. The default value is 90%.

Alert Reset Interval (Hours)

The amount of time the software will wait before re-issuing an alert that it has already issued. For example, if you set the Mirroring Buffer Threshold 1 to be 10% and the Alert Reset Interval to two hours, the first alert will be issued when the mirror buffer is 10% full. The software will not issue the Threshold 1 alert again for the next two hours. If at that time the mirror buffer usage is still beyond the 10% threshold, the Threshold 1 alert will be issued again. The default value is 24 hours.

Select Volume

List of Volumes

Select the mirrored file volume for which you would like to see network statistics.

Status

Transactions (transactions/second)

Incoming

The incoming transaction statistics for the selected volume, in terms of transactions per second:

• Avg - The average number of transactions per second traveling into the active server.
• Min - The lowest number of transactions per second that has traveled into the active server. The date and time that this number of transactions occurred is shown on the right, if available.
• Max - The largest number of transactions per second that has traveled into the active server. The date and time that this number of transactions occurred is shown on the right, if available.

Outgoing

The outgoing transaction statistics for the selected volume, in terms of transactions per second:

• Avg - The average number of transactions per second traveling from the active server to the mirror server.
• Min - The lowest number of transactions per second that has traveled from the active server to the mirror server. The date and time that this number of transactions occurred is shown on the right, if available.
• Max - The largest number of transactions per second that has traveled from the active server to the mirror server. The date and time that this number of transactions occurred is shown on the right, if available.

Mirror Buffer (transactions)

Size

The size of the mirror buffer, in terms of transactions (not bytes).

Free

The number of transactions left in the mirror buffer.

Utilization

The percentage of mirror buffer that is currently being used to hold transactions. If this value approaches 100%,check to make sure that all network links are functioning properly. In the event that a network link goes down, the buffer will be filled up and eventually overrun. This means that transactions are travelling into the active system faster than they are travelling into the mirror system, filling up the buffer. When the buffer is overrun, the mirror has been cracked.

After the network link is repaired, the system will begin the mirror update process until the mirrored file volume is back in sync. There can be no I/O activity to the mirror volume during the resync. The volume is taken offline to avoid transient file system errors and inconsistencies.

Fill Rate

The rate at which the mirror buffer is filling, transactions per second. If the fill rate is greater than zero, check that all network links are functioning properly. If a network link is disabled, transactions travel into the active system faster than they are travelling into the mirror system, filling up the buffer. If the buffer is overrun, the mirror has been cracked.

After the network link is repaired, the system begins the mirror update process until the mirrored file volume is back in sync. There can be no I/O activity to the mirror volume during the resync. The volume is taken offline to avoid transient file system errors and inconsistencies.

Note: If you clear this checkbox, any checkpoints taken already will be deleted immediately, regardless of their defined retention.

Checkpoint Configuration

Options that configure checkpoint processing:

• Use for Backups - Select if you plan to create NDMP backups for the file volume. NDMP performs backups from a copy of the file volume, thereby avoiding potential problems that can occur when working with live data. The backup checkpoint will be deleted immediately after finishing the backup.
• Automatic - Select to create and remove checkpoints based on a user-configured schedule.

Enable Quotas

Click to enable quotas for the selected volume.

Enable Attic

Click to temporarily save deleted files in the.attic$ directory located at the root of the volume. By default, this option is enabled.

In rare cases on very busy file systems, the .attic$ directory can be filled faster than it processes deletes, leading to a lack of free space and slow performance. In such a case, disable the .attic$ directory by deselecting this option.

Compliance Archiving

These options are available only if you enabled the advisory compliance enforcement version of the compliance archiving software when you created the volume. Options that enable you to configure compliance archiving software:

• Enabled - An indicator of whether the volume has compliance archiving software enabled.
• Mandatory (No Administrator Override) - The volume is mandatory compliant. You cannot configure this volume to be advisory compliant.
• Advisory (Allow Administrator Override) - The volume is advisory compliant. If you want to enable mandatory compliance, you must upgrade to the Mandatory Compliant version of the software, and this is a one-time event.
• Default Retention Period - Click to specify how long WORM (write once, read many) files will be retained on the volume if the client does not provide a retention time. The default retention period for a volume is used if a retention period is not applied to a file before that file is retained. Changing the default retention period for a volume does not affect files that have already been retained.
