Advanced Backup - Exchange Mailbox (Classic) Agent

Table of Contents

For more information about the different types of backups, see Backup Overview.

Full Backups

Full backups provide the most comprehensive protection of data.

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient and click Backup.
  3. Select Full as backup type and Immediate to run the job immediately.
  4. Click OK.

    You can track the progress of the job from the Job Controller or Event Viewer window.

Incremental Backups

An incremental backup contains only data that is new or has changed since the last backup, regardless of the type. On average, incremental backups consume less media and use fewer resources than full backups. 

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. Select Incremental as backup type and Immediate to run the job immediately.
  4. Click OK.

    You can track the progress of the job from the Job Controller or Event Viewer window.

Differential Backups

A differential backup contains only the data that is new or has changed since the last full backup. Like incremental backups, differential backups also consume less media and use fewer resources than full backups. Differential backups are cumulative. This means that each differential backup contains all of the changes that have accumulated since the last full backup. Each successive differential backup contains all of the changes from the previous differential backup.

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. From the Backup Options dialog box, select from the following options:
    • Backup Type: Select Differential.
    • Backup Schedule: Select Run Immediately
  4. Click OK.

    You can track the progress of the backup job from the Job Controller window.

    When the backup has completed, the Job Controller displays Completed.

Synthetic Full Backups

A synthetic full backup is a synthesized backup, created from the most recent full backup and subsequent incremental and/or differential backups. The resulting synthetic full backup is identical to a full backup for the subclient.

Unlike full, incremental, and differential backups, a synthetic full backup does not actually transfer data from a client computer to the backup media. Therefore, they do not use any resources on the client computer.

Synthetic full backups are media-based; they read backup data from one media and simultaneously write (restore) the result to the new active media within the same media group. As a result, synthetic full backups require that at least two media drives for the same storage policy be available at the time the job is started. Synthetic full backups cannot be performed on subclients where the storage policy is associated with a stand-alone drive.

Running Synthetic Full Backups

Synthetic full backups can either be started manually or scheduled to occur at regular intervals.

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. From the Backup Options window, select Synthetic Full for Backup Type.
  4. Select Immediate for Job Initiation.
  5. Click OK.

    You can track the progress of the backup job from the Job Controller. When the backup has completed, the Job Controller displays Completed.

Running an Incremental Backup Before or After a Synthetic Full Backup

An incremental backup can be run before or after a synthetic full backup.

  • Running an incremental backup before the synthetic full ensures that any new or recently changed data is included in the synthetic full.
  • Running an incremental backup after the synthetic full ensures that any new or recently changed data since the backup that occurred prior to the synthetic full, but was not included in the synthetic full, is backed up by the incremental.

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. From the Backup Options window, select Synthetic Full for Backup Type.
  4. Select Run Incremental Backup and then select Before Synthetic Full or After Synthetic Full options.
  5. Select Immediate for Job Initiation.
  6. Click OK.

    You can track the progress of the backup job from the Job Controller. When the backup has completed, the Job Controller displays Completed.

Verifying Synthetic Full Backups

This option ensures that messages that have not been backed up by incremental jobs since the last full backup are backed up by the next incremental.

For example, you perform the conventional full backup only once for a specific subclient and then perform incremental (or differential) backups and periodic synthetic full backups. After the conventional full backup, a message is added to the subclient and the message has a time stamp that is older than the time of full backup. In this case, the message will never be backed up. Eventually, such messages might be pruned and no backup of such messages will be available.

To prevent this situation, periodically verify the synthetic full backups job.

Procedure

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. From the Backup Options dialog box, select Synthetic Full.
  4. Click Advanced.
  5. In the Advanced Backup Options dialog box, click the Data tab.
  6. Select Verify Synthetic Full.
  7. Click OK.

Accelerated Synthetic Full Backups (DASH Full)

When a storage policy copy is deduplicated, synthetic full backups can be created in an accelerated mode to significantly reduce the copy duration. This is done by identifying and transferring the data signatures (instead of the data itself) to the target wherever possible.

To enable DASH full on a storage policy copy, see Modifying a Storage Policy Copy Deduplication Settings.

Scheduling a Backup

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click the subclient, and then click Backup.
  3. Select the backup type
  4. Click Schedule
  5. Click Configure
  6. Select Schedule Options. For example:
    1. Click Weekly.
    2. Check the days you want the run the backup job.
    3. Change the Start Time to 9:00 PM.
  7. Click OK.

    The backup job runs according to the schedule

Managing Jobs

The following sections provide information on the various options available for job management.

Restarting Jobs

Jobs that fail to complete successfully are automatically restarted based on the job restartability configuration set in the Control Panel.

Changes made to this configuration will affect all jobs in the entire CommCell.

To configure the job restartability for a specific job, you can modify the retry settings for that job. This will override the setting in the Control Panel. It is also possible to override the default CommServe configuration for individual jobs by configuring retry settings when initiating the job. This configuration, however, will apply only to the specific job.

Backup jobs for this Agent are resumed from the point-of-failure.

Configure Job Restartability at the CommServe Level

  1. From the CommCell Console ribbon, click the Home tab, and then click Control Panel.
  2. Under Data, click Job Management.

    The Job Management dialog box appears.

  3. Click the Job Restarts tab.
  4. From the Job Type list, select the appropriate item.
  5. Select the Restartable check box to make the job restartable.
  6. In the Max Restarts box, change the maximum number of times the Job Manager will try to restart a job.
  7. In the Restart Interval (Mins) box, change the time interval between attempts for the Job Manager to restart the job.
  8. Click OK.

Configure Job Restartability for an Individual Job

  1. From the CommCell Console, expand Client Computers > client > agent > defaultBackupSet.
  2. Right-click subclient, and then click Backup.
  3. Click Advanced.
  4. In the Advanced Backup Options dialog box, click the Job Retry tab.
  5. Select Enable Total Running Time and specify the maximum elapsed time before a job can be restarted or killed.
  6. Select Kill Running Jobs When Total Running Time Expires to kill the job after reaching the maximum elapsed time.
  7. Select Enable Number Of Retries and specify the number of retries.
  8. Click OK.

Controlling Jobs

The following controls are available for running jobs in the Job Controller window:

Suspend

Temporarily stops a job. A suspended job is not terminated; it can be restarted at a later time.

Resume

Resumes a job and returns the status to Waiting, Pending, Queued, or Running. The status depends on the availability of resources, the state of the Operation Windows, or the Activity Control setting.

Kill

Terminates a job.

Suspending a Job

  1. From the Job Controller of the CommCell Console, right-click the job and select Suspend.
  2. The job status may change to Suspend Pending for a few moments while the operation completes. The job status then changes to Suspended.

Resuming a Job

  1. From the Job Controller of the CommCell Console, right-click the job and select Resume.
  2. As the Job Manager attempts to restart the job, the job status changes to Waiting, Pending, or Running.

Killing a Job

  1. From the Job Controller of the CommCell Console, right-click the job and select Kill.
  2. Click Yes when the confirmation prompt appears if you are sure you want to kill the job. The job status may change to Kill Pending for a few moments while the operation completes. Once completed, the job status will change to Killed and it will be removed from the Job Controller window after five minutes.
