Back Up Data Using Disk Staging

Prior to performing a backup job using disk staging (B2D2T), you must have already configured the staging groups. If you did not configure Arcserve Backup to use disk staging, see How to Configure Arcserve Backup to Perform Disk Staging Backups.

Arcserve Backup provides you with the capability to submit a backup job using either the Backup Manager or the command line utility. This information describes how to perform a disk staging backup job using the Backup Manager. For information about how to submit a staging backup job using the command line, see the Command Line Reference Guide.

Note: Before you can back up data using disk staging, ensure that all preconfiguration tasks are complete and licensing requirements are fulfilled. For more information, see Licensing Requirements for Staging Backups.

Back up data using disk staging

1. Open the Backup Manager.

   Click the Start tab, select Normal, Deduplication, or UNIX/Linux Data Mover, and then click the Enable Staging check box.

   The Staging Location and Policies tabs appear.

2. Click the Source tab, browse to and select the source objects that you want to back up.
3. Click the Schedule tab and specify the schedule that you want to use for the backup job.

   Note: For more information, see Rotation Schemes and Custom Schedules.

4. Click the Staging Location tab and expand the Staging Servers object.

   Browse to and select the staging group that you want to use for the backup job. If you selected a deduplication job on the Start tab, choose a deduplication device group from the Staging Location tab.

5. Click the Policies tab. Complete the following Staging Policies required for the job:
   • Full Backup--Specify the Copy and Purge policies for full backups required for the job.

     (optional)--Click Enable Snaplock.

   • Incremental/Differential Backup--Specify the Copy and Purge policies for incremental and differential backups required for the job.

     (optional)--Click Enable Snaplock.

     Note: For more information, see Specify Copy and Purge Policies for Disk Staging Backups.

   • Miscellaneous--Specify the Miscellaneous policies required for the backup job.

     Note: For more information, see Specify Miscellaneous Options for Disk Staging Backups.

   • Alert--Specify the Alert policies required for the backup job.

     Note: For more information, see Specify Alert Options for Disk and Tape Staging Backups.

   • Postscripts--Specify the Postscript policies required for the job.

     Note: For more information, see Specify Postscripts Options for Disk and Tape Staging Backups.

6. Click the Destination tab and expand the Servers object.

   Browse to and select the destination device you want to use for the migration job. If desired, you may choose a deduplication device group as the final destination provided it is not the same deduplication device group selected as the staging group.

   Note: You can also have the option to perform a Double Tape Copy. Double Tape Copy lets you migrate (copy) the data to two destinations simultaneously. Using this feature writes to the destinations in parallel to save time. To do this, select the Create Duplicate in-line check box from the Destination tab. For more details, see Backup Manager Destination Options.

7. Click the Options on the toolbar.

   The Options dialog opens.

8. Select the Encryption/Compression tab and complete the following fields for the backup job, provided you are not using deduplication devices:
   • Session/Encryption password--Specify a Session/encryption password to restore this data from media.

     Important! If you specify a Session/Encryption password, you must provide this password to restore the session.

   • Encrypt data--Use this option to encrypt the backup data. You can specify one of the following options:
     • At agent--Select this option to encrypt the backup data prior to the actual backup process. For more information about this option, see Data Encryption at the Agent Server.
     • At backup server during backup--Select this option to encrypt the backup data at the backup server during the backup process. For more information, see Data Encryption During Backup.
     • At backup server during migration--Select this option to encrypt the backup data during the migration phase of a staging backup job. For more information, see Data Encryption During Migration.
   • Compress data--Use this option to compress the backup data. You can specify one of the following options:
     • At agent--Select this option to compress the backup data on the system where the agent is installed and running.
     • At backup server--Select this option to compress the backup data at the Arcserve Backup server during the backup process. Using this option directs Arcserve Backup to compress files before backing them up using a software compression algorithm.

       Note: When you use data compression at the backup server before data encryption, the amount of space required to store the data on the staging device can be two times the size of the source files. Because of this limitation, we discourage the use of compression before encryption when backing up to disk.

   Be aware of the following considerations that affect encryption and compression:

   • If you want to apply other options that affect the migration job, you should do so at this time. For example, to eject the tape from a library after the migration job is complete, click the Operation tab on the Global Options dialog and select the Eject Media option.
   • If you specify encryption and compression options, and the backup destination is a drive that does not support compression, or is a file system device (FSD), Arcserve Backup encrypts the backup data and does not compress the backup data.
   • Encryption and compression are not supported on deduplication devices. However, if you select a regular FSD for either the staging or final destinations, you may enable encryption or compression, as needed. For more information, see the topic, Compression and Encryption with Deduplication.
9. Click Submit on the toolbar to submit the backup job.

   The Submit Job dialog opens.

10. Complete the required fields on the Submit Job dialog and click OK.

    The job is submitted.
