[<<machine name>>] <<job no>>

Last Result

The last result is determined from the following criteria:

• The status is marked as failed if any of the sessions in the host fail.
• The status is marked as incomplete in any of the sessions are incomplete even if some are successful.
• The status is marked as successful only if all sessions are successful.

MB

The amount of data backed up for the host.

Files

The number of files backed up for the host.

Missed

The number of files missed during the backup job.

Note: Use Arcserve Backup Agent for Open Files to avoid missed files during a backup job.

MB/Minute

• At the Job level, MB/Minute indicates the ratio of megabytes and the elapsed time for the entire job, including pre and post scripts, if any, media management activities, and so on. For average master job throughput, refer to the Activity Log.
• At the Session level, MB/Minute indicates the ratio of megabytes and the elapsed time for a specific volume and its folders, which comprise a single session.

Time Used

• At the Job level, Time Used indicates the elapsed time for the entire job including pre and post scripts, if any, media management activities, and so on.
• At the Session level, Time Used indicates the elapsed time for the backup of a specific volume and its folders, which comprise a single session.

Session Number

Identifies the serial number of a session on a media. For example, session number 4, this is the fourth session on the media.

Identifies session number of the session that contains the backup data.

Subsession Number

Identifies the serial number of the logical session in a physical session when a virtual machine (VM) is backed up by the Agent for Virtual Machines. If Arcserve Backup backs up a VM using the Agent for Virtual Machines, Arcserve Backup backs up all volumes and components into a single session. Each volume or component is backed up in a logical session. This logical session contains the serial number, which is the subsession number.
