NAS Integration with Symantec™ Backup Exec™ 2010 Abstract This guide provides step by step instructions on how to configure and optimize Symantec Backup Exec 2010 in order to back up to HP D2D Backup Systems using a CIFS backup target.

"local D2D users" from the D2D Web Management Interface. This mode requires the configuration of a respective local user on the Backup Exec media server and configuration changes to the Backup Exec services. Individual users can then be assigned access to individual shares on the D2D Backup System - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 5
named user on the Windows server that hosts the Backup Exec Media server. 3. It is then necessary to configure Backup Exec to use this Local user account as the credentials used to run its services.

Exec services before continuing with configuration. Note, however, that this is the ONLY user account that the Backup Exec Media server will be able to use to connect to remote storage that requires authentication, so this account must be the same for any other disk storage devices. Configuring - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 7
network, the user must also configure the domain's DNS server to be able to correctly manage the D2D shares, as described in the next section. To configure entries manually if the DNS server does not update automatically From a Windows client server that has domain and DNS management tools installed - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 8
2. Now that the D2D Backup System is a member of the domain its shares can be managed from any computer on the domain by configuring a customized Microsoft Management Console (MMC) with the Shared Folders snap-in. To do this first open a new MMC window by typing mmc at the command prompt or from the - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 9
3. To this empty MMC window add the Shared Folders snap-in. Select File - Add/Remove Snap-in ..., then select Shared Folders from the left-hand pane. 4. Click Add > and in the dialog box choose the computer to be managed and select Shares from the View options. 5. Click Finish and OK to complete - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 10
an internal path on the D2D Backup System. 6. Save this customized snap-in for future use. 7. Select the Share Permissions tab and Add a user or group of users from the domain. Specify the level of permission that the users will receive and click Apply. 8. Now, from any Windows server on the domain - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 11
back into a Windows client before it is possible to access the D2D shares. 9. It may also be necessary to configure Backup Exec to use this AD Domain user account as the credentials used to run its services. Do this from the Backup Exec interface by selecting Tools - Backup Exec Services .... Select - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 12
described, so that the share is accessible to the appropriate users. After that it is possible to access the share from the Windows server, for example by clicking the Network Path link from the Shares page which will open a Windows Explorer window. 12 Configure Backup Exec to use D2D CIFS Share - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 13
and configuration of a Backup-To-Disk folder. Enter a name for this folder that Backup Exec will use to identify it. A best practice is to use the name of the D2D Backup System and share name in order to easily identify where this backup-to-disk folder resides. Create a Backup Exec Backup-to-disk - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 14
result in incorrectly reported deduplication ratio, and also poor performance or failures because the D2D Backup System will need to "pad" the data file when created. 6. Configure the maximum size that each Backup-To-Disk file may reach before spanning to a new file. The default size is 4GB; however - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 15
to start replicating backup files before the whole backup completes. However this may reduce backup performance, if the D2D Backup System is heavily loaded with other backups or housekeeping processes. 7. Configure the Maximum number of backup sets that can be held in each backup to disk file. This - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 16
. See the D2D Best Practices for VTL, NAS and Replication implementations for more information on the maximum number of concurrently open deduplicated and pre-deduplicated files per D2D Share and per D2D Backup System appliance for different D2D Backup System models. 9. Configure the Low Disk Space - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 17
. Finally Backup Exec will present a summary of the Backup-To-Disk folder configuration before creating the folder. Once complete the Backup-To-Disk device will be created and presented on the Devices page in Backup Exec. At creation time two small configuration files will be created on the D2D CIFS - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 18
The following is an example of a "Best Practice" backup rotation and retention scheme configuration with Backup Exec. This scheme observes the following best practices: • Backup-To-Disk files are never appended to; appended backups reduce replication performance, prevent files from being overwritten - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 19

It is also useful to change the Media overwrite options. From the Tools - Options menu select Media Management and change the - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 20
policy can be created from the Job Setup page on the Backup Exec User interface. There is a default backup policy that is similar to the required scheme in this example, so copying this provides a start point for modification. 2. Once copied the new template can - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 21

(The D2D Backup System will always deduplicate and compress the data; enabling software compression will slow the backup job and result in a worse deduplication ratio so should - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 22

In order to ensure that multiple backup streams run concurrently to the Backup-To-Disk folder (assuming the concurrency value for the folder - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 23
6. The last step in the process is to create backup jobs based on the Policy and Selection Lists. Select the New Jobs Using this policy option from the tasks panel, then select the Selection lists for which jobs will be generated. 7. The jobs will be created and will run according to the schedule - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 24
Backup Exec will overwrite each file in turn as a new job starts. Because the backups are configured to use one Backup-To-Disk file per backup the housekeeping process will not start until the new backup has completed and thus will not interfere with the backup. However, if multiple jobs are running - HP D2D | .D2D NAS Integration with Symantec Backup Exec 2010 (EH985-90932, March - Page 25
