Specify Protection Settings

CA ARCserve Central Protection Manager lets you specify the protection settings for the data that you want to back up.

To specify protection settings

  1. From the CA ARCserve Central Protection Manager home page, click Policies on the Navigation bar.

    The Policies screen opens.

  2. Click New to create a new policy.

    The New Policy dialog opens, displaying the Protection Settings option of the Backup Settings tab.

  3. Specify the Backup Destination.

    You can specify a local path (volume or folder), or remote shared folder (or mapped drive) for the backup location.

    1. If you specify to back up to your local path (volume or folder), the specified backup destination cannot be the same location as your backup source. If you inadvertently include the source in your destination, the backup job ignores this portion of the source and not include it in the backup.

      For example, if you are attempting to back up your entire local computer which consists of Volumes C, D, and E; and also specify Volume E as your destination, CA ARCserve D2D backs up only Volumes C and D to Volume E. Data from Volume E is not included in the backup. If you want to back up all local volumes, specify a remote location for your destination.

      Important! Verify that your specified destination volume does not contain system information or else it will not be protected (backed up) and your system will fail to recover after Bare Metal Recovery (BMR), if necessary.

      Note: Dynamic disks cannot be restored at disk level. If your data is backed up to a volume on a dynamic disk, you cannot restore this dynamic disk during BMR.

    2. If you choose to back up to a remote shared location, it is imperative that you specify a location path or browse to the location and provide user credentials (User name and Password) to access the remote computer.
    3. If the specified backup destination has changed since the last backup was performed, it is required that you select the backup type. These options are enabled when you change your backup destination. The available options are Full Backup and Incremental Backup.
      • Full Backup--Specifies that the next backup performed is a full backup. The new backup destination does not have any dependency on the old backup destination. If you continue with a full backup, the previous location is no longer needed for backups to continue. You can choose to keep the old backup for any restores or delete it if you do not want to perform any restores from there. It will not affect future backups.
      • Incremental Backup--Specifies that the next backup performed is an incremental backup. The next incremental backup to the new destination is performed without copying all the backups from the previous destination. However, the new location is dependent on the previous location because the changes include only the incremental data (not the full backup data). Do not delete the data from the previous location. If you change the backup destination to another folder, and attempt to perform an incremental backup and the former backup destination does not exist, the backup will fail.
  4. Specify the Backup Source.

    You can specify to back up the entire computer or an individual volume on your computer.

  5. Specify the Retention Setting.

    You can set the retention policy that is based on the number of recovery points to retain (merges sessions) or based on the number of recovery sets to retain (deletes recovery sets and disables infinite incrementals).

    Default: Retain Recovery Points

    Retain Recovery Points

    Select this option to specify the number of recovery points (full, incremental, and verify backup images) to retain.

    Retain Recovery Sets

    Select this option to specify the number of recovery sets to retain. With this setting, you can disable infinite incremental backups forever, without merging any sessions. Using recovery sets helps resolve the time that it takes to complete merge jobs.

  6. Specify the type of Compression.

    Select this option to specify the type of compression that you want to use for backups.

    Compression decreases your disk space usage, but also has an inverse impact on your backup speed due to the increased CPU usage.

    The available compression options are as follows:

    Be aware of the following scenarios:

  7. Specify the Encryption settings.
    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. CA ARCserve D2D data protection uses secure, AES (Advanced Encryption Standard) encryption algorithms to achieve 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 and verify backups must use same encryption algorithm.
      • If the encryption algorithm for an incremental or verify backup is changed, a full backup must be performed. This means after changing encryption algorithm, the first backup will be full, despite the original backup type.

        For example, if you change the algorithm format and submit a customized incremental or verify backup manually, it automatically converts to a full backup.

    2. When an encryption algorithm is selected, 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 and verify backups must use same password to encrypt data.
      • If the encryption password for an incremental or verify backup is changed, a full backup must be performed. This means after changing encryption password, the first backup will be full, despite the original backup type.

        For example, if you change the encryption password and submit a customized incremental or verify backup manually, it automatically converts to a full backup.

    3. CA ARCserve D2D provides encryption password management so that you do not need to remember encryption passwords.
      • Password will also be encrypted.
      • Password will be remembered and not required if you restore to the same machine.
      • Password is required if you restore to a different machine.
      • Password is not required if you are attempting to export a recovery point that contains encrypted data and the recovery point belongs to backups performed on the current machine.
      • Password is always required if you are attempting to recover encrypted data from an exported recovery point.
      • Password is not required to browse to an encrypted recovery point.
      • Password is required to perform a BMR.
    4. When encryption is enabled the activity log will be updated.
      • A message will be recorded in the activity log to describe the selected encryption algorithm for every backup.
      • A message will be recorded in the activity log to indicate why an incremental or verify backup was converted to a full backup (password change or algorithm change).

    Note: Encryption settings do not have to remain the same for your backups. You can change these settings at any time, including after several backups of the same data.

  8. Specify the Throttle Backup.

    You can specify the maximum speed (MB/min) at which backups will be written. You can throttle the backup speed to reduce CPU or network utilization. However, by limiting the backup speed, it will have an adverse affect on the backup window. As you lower the maximum backup speed it will increase the amount of time of perform the backup.

    Note: By default, the Throttle Backup option is not enabled and backup speed is not being controlled.

  9. Click Save.

The protection settings are saved.
