Specify the Backup Destination

Specify a location to store the backed up data (recovery points) in the Backup Destination page of the Backup Wizard. The backup destination could be an NFS share, a CIFS share, or Source local. Source local is the backup source node. If your backup destination is Source local, then the backup data is written to its own local disk directly.

If a physical disk includes two logical volumes, then you can specify one volume as the backup source and the other volume as the backup destination.

Note: If you select Source local as your backup destination, the Backup Server cannot manage the recovery points. To manage the recovery sets, see Manage the Recovery Sets in How to Manage the Backup Server Settings.

Follow these steps:

1. Select a destination from the Backup Destination drop-down list and enter the complete path of the storage location.
   • If you have selected NFS share, then type the Backup Destination detail in the following format:

     IP address of the NFS Share:/full path of the storage location
     

     Note: Some versions of Data Domain NAS do not support the file locking mechanism of NFS. As a result, such NFS share cannot be used as a backup destination. For more information about this issue, see Compatibility Issues with Arcserve UDP Agent (Linux) in the Release Notes.

   • If you have selected CIFS share, then type the Backup Destination detail in the following format:

     //hostname/share_folder
     

     Note: The shared folder name cannot contain any spaces.

   • If you have selected Source local, then you have to modify some settings so that the Backup Server can manage the recovery points. For example, consider server-A as the host name of the Backup Server and node-B as the host name of the source node. Now, follow these steps to modify the settings of node-B:
     • Ensure that the NFS server is running. You can run the following command to verify the NFS server status:

       service nfs status

     • If the NFS server is not running, run the following command to start the NFS server:

       service nfs start

     • If your backup destination folder on node-B is /backup/test, then add the following line to /etc/exports:

       /backup/test server-A(rw,no_root_squash)

       Now, run the following command:

       exportfs -a

     • On the Backup Server UI, add node-B:/backup/test as a backup storage location. The Source local storage location is displayed in the Backup Destination drop-down list.
2. Click the arrow button to validate the Backup Destination information.

   If the backup destination is invalid, an error message is displayed.

3. Select a compression level from the Compression drop-down list to specify a type of compression that is used for backup.

   The available options for Compression are:

   Standard Compression

   Specifies that this option provides a good balance between the CPU usage and the disk space usage. This compression is the default setting.

   Maximum Compression

   Specifies that this option provides the highest CPU usage (lowest speed), but also has the lowest disk space usage for your backup image.

4. Select an algorithm from the Encryption Algorithm drop-down list and type the encryption password, if necessary.
   1. Select the type of encryption algorithm that you want to use for backups.

      Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. Arcserve UDP Agent (Linux) data protection uses secure, AES (Advanced Encryption Standard) encryption algorithms to achieve the maximum security and privacy of your specified data.

      The available format options are No Encryption, AES-128, AES-192, and AES-256. (To disable encryption, select No Encryption).

      • A full backup and all its related incremental backups must use the same encryption algorithm.
      • If the encryption algorithm for an incremental backup has changed, you must perform a full backup.

        For example, if you change the algorithm format and then you run an incremental backup, then the backup type automatically converts to a full backup.

   2. When an encryption algorithm is selected, you must provide (and confirm) an encryption password.
      • The encryption password is limited to a maximum of 23 characters.
      • A full backup and all its related incremental backups use the same password to encrypt data.
