2 Setting up for Unix/Linux environment backup NOTE: Before you begin, ensure that you can mount/verify the NFS share from the UNIX/Linux client system. For more details, please refer to the Amanda documentation at: http://docs.zmanda.com/Project:Amanda_Enterprise_3.3/ZMC_Users_Manual You can access the zmanda Management Console for Amanda in a Web browser by navigating to and logging on at the following location: https://:/ 2.
2.2 Creating the storage devices Before you begin, log on to the Amanda server and add the DR Series system nfs mount. Run the following commands to use the DR Series system container as a backup target in the Amanda backup server: mkdir chmod chown mount –p -R -R –t /mnt/DR_container_amanda 700 '/mnt/DR_container_amanda' amandabackup:disk '/mnt/DR_container_amanda' nfs :/containers/amanda-src /mnt/DR_container_amanda Then, follow these steps to create the storage devices. 1.

3 Creating a new backup job with the DR Series system as the target 3.1 Defining the backup set In the zmanda Management Console, Backup what defines the host system and directories to include in the backup set. 1. On the Backup tab, click what, and on the File Systems drop-down menu, select Linux. 2. Enter the host name and location of the folder to back up, and then click Add. Note: For better space savings, Dell recommends that the Encrypt and Compress options be set to none.
Upon successful addition, the data set will be listed at the bottom of the management console window. 3.2 Defining where to back up 1. On the Backup tab in the zmanda Management Console for Amanda, click where. 2. Select the storage device that you created previously (that is, the DR Series system), and then click Use. 3. Click Add. 15 Setting Up the Dell™ DR Series System as an NFS Target on Amanda Enterprise 3.3.
The DR Series system is added. 16 Setting Up the Dell™ DR Series System as an NFS Target on Amanda Enterprise 3.3.
3.3 Staging a backup In the zmanda Management Console you can define a staging area (an optional write-cache mechanism), which stores the backup image on the server's hard disk. Because backups can be written in parallel to the staging area, backups can be completed in smaller windows than if writing directly to the device. To set up a staging configuration, on the Backup tab, click staging. You can change the default options as needed. For more information, see the Amanda documentation. 3.
3.5 Defining additional backup settings After you have defined what, where, and when for the backup set in the zmanda Management Console, you can use the Backup How page to define key internal parameters that control how the backup set will run after it has been activated. In most situations, the default settings are appropriate. Before adjusting these settings, advanced users should study the logs and reports of previous backups, and modify parameters for each backup set as needed. 1.
3.6 Activating a backup A backup set must be activated for automatically-scheduled backups to execute. Backup sets must be activated individually. 1. On the Backup tab, click now. 2. In the Backup Set Activation section, click Activate Now to activate a backup set. 3. For immediate execution of a backup set, click Start Backup Now in the Immediate Backup section. You can execute an immediate backup at any time.

4 Creating a new restore job 4.1 Defining what to restore On the Restore What page you can define the data to restore. You can select a single file or a single directory or all directories/files under a single directory. 1. On the Restore tab, click what. 2. In the What would you like to restore from pane, specify which backup image is to be restored. 3.
4.2 Defining where to restore The Run Restore process is the last step in the recovery process. In the Run Restore page, you can review the restore options you have specified, start the actual restore process, and monitor progress. Note: Only one restore process can be performed for a backup set in the zmanda Management Console. 1. On the Restore tab, click where. The Restore From, Restore To, and Tapes Needed panels provide information about the restore job.
4.3 Defining how to restore On the Restore tab, click how. On this page you can configure the conflict resolution policies during restoration of file system. Note: You can select different options for directory and file name conflicts. Dell recommends to restore to a new directory so there will be no conflicts. 4.4 Performing the restore 1. On the Restore tab, click now. 2. Define the settings on this page as needed.
3. 24 Click the Restore button to start the restore process. Setting Up the Dell™ DR Series System as an NFS Target on Amanda Enterprise 3.3.
5 Setting up DR Series system native replication and restore from the replication target container 5.1 Building a replication relationship between DR Series systems This section will refer to the example DR Series system and container amand-src as the source DR and replication source respectively. Replication can be set up when no backups have been taken on the source or after the source has some backups. 1.
5. Click Create Replication. 6. Verify that the replication is created successfully, and that the Status column shows a check box for the replication session. 26 Setting Up the Dell™ DR Series System as an NFS Target on Amanda Enterprise 3.3.
7. 5.2 Select the replication session, and then click Start to start the replication. Once replication has completed, the Status column will display the status, INSYNC. Restoring data from the target DR Series system Before you begin, ensure the following: The replication session has a Peer Status of Online if restoring from the replication target is needed, The replication is in an INSYNC state from the Replication Statistics menu before Stopping/Deleting the replication.
The Status will change to a warning when the replication stops. 3. Delete the replication by selecting the replication pair and clicking Delete at the top of the page. Follow the on-screen prompts and then click Delete Selected Replication. 28 Setting Up the Dell™ DR Series System as an NFS Target on Amanda Enterprise 3.3.
A message is displayed when the Replication is successfully deleted. 4. Log on to the Amanda Server, and unmount the DR Series system source container, for example amanda-src, mounted at /mnt/DR_container_amanda: umount /mnt/DR_container_amanda 5. On the same mount point, mount the DR Series system replication target container, for example: mount –t nfs :/containers/replication-target /mnt/DRNFSContainer 6.
6 Setting up the DR Series system cleaner Performing scheduled disk space reclamation operations are recommended as a method for recovering disk space from system containers in which files were deleted as a result of deduplication. The system cleaner runs during idle time. If your workflow does not have a sufficient amount of idle time on a daily basis, then you should consider scheduling the cleaner to force it to run during a scheduled time.
7 Monitoring deduplication, compression and performance After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the DR Series system dashboard. This information is valuable in understanding the benefits of the DR Series system. Note: Deduplication ratios increase over time. It is not uncommon to see a 2-4x reduction (25-50% total savings) on the initial backup. As additional full backup jobs are completed, the ratios will increase.
