IntelliSnap - Advanced Backup - Windows File System iDataAgent

Full Backup

Procedure

  1. Full backups provide the most comprehensive protection of data. From the CommCell Browser, navigate to <Client> | File System | 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. When the backup has completed, the Job Controller displays Completed.

Incremental Backup

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 less resources than full backups.

The illustration clarifies the nature of full and incremental backups.

Follow steps given below to perform an incremental backup:

incremental

  1. From the CommCell Browser, navigate to <Client> | File System | defaultBackupSet.

  2. Right click the <Subclient> and 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. When the backup has completed, the Job Controller displays Completed.

Differential Backup

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 less resources than full backups. Differential backups are cumulative. This means that each differential backup contains all changes accumulated since the last full backup. Each successive differential backup contains all the changes from the previous differential backup.

The illustration on the right demonstrates the nature of differential backups. For simplicity, assume there is a file system that contains six files as represented in the figure.

differential

  1. From the CommCell Browser, navigate to <Client> | File System | defaultBackupSet.

  2. Right click the <Subclient> and click Backup.

  3. Select Differential as a backup type and Immediate to run the job immediately.

  4. 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.

Synthetic Full Backups for IntelliSnap

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

Synthetic full backups are performed on the backup copy. If you choose to run incremental backups forever, then performing a synthetic full backup eliminates the need to run a full snapshot backup and a backup copy job of that full snapshot backup.

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.

Note: To run incremental backups forever, make sure that you use a snapshot copy on the storage policy and specify a data aging rule that includes the Retain Snaps by Number of Jobs option with a number of jobs that matches your backup cycle. This ensures that the previous backup jobs are pruned on a regular basis. For more information, see Data Aging for IntelliSnap Snapshots.

Before You Begin

  • This feature applies to new clients on Commvault Version 11 software. If you upgrade the client from the previous version, and the client still operates on Indexing Version 1, then synthetic full backups are not supported.

  • Ensure that any incremental or differential backups have been written to the media by performing the task in Configuring a Backup Copy for IntelliSnap Backup.

  • For the storage policy associated with the synthetic full job, IntelliSnap jobs that should not be included in the synthetic full backup should not be picked for backup copy as described in Disabling a Job for Backup Copy.

Procedure

Synthetic full backups are enabled by default. Perform the following steps to disable synthetic full backups for IntelliSnap.

  1. From the CommCell Browser, right-click the CommCell entry (top-level node); then click Properties.

  2. On the CommCell Properties dialog, click the Additional Settings tab, click Add, and enter the following values:

    Depending upon your selection, the mount point data will be included or excluded from the default subclient backup.

Note

When backups are run from multiple nodes on clustered file systems, the same content is backed up multiple times. Backups should be run on only one node to avoid such duplicate content backups. However, the other nodes can also be configured to run backups but make sure that the clustered file system mount point is added to the file system exclusion list of the physical machine's subclients.

For VERITAS Cluster File System, the clustered file system mount point is added automatically to the file system exclusion list when backup is run for the first time on the virtual node/s.

Backing Up System Protected Files

The system protected files are the critical files that are installed as a part of windows operating system installation. For example, files with a .dll, .exe, .ocx, and .sys extension and some True Type fonts.

The system protected files are backed up by default via System State. Follow the steps given below to exclude these files from a backup:

  1. From the CommCell Console, navigate to <Client> | File System | defaultBackupSet.
