If you chose to use short-term protection using tape, you need to specify your short-term tape-based recovery goals. Your recovery goals are defined by the configuration of retention range, synchronization frequency, and recovery point schedule. DPM provides default settings for the recovery goals; however, you can modify each or all of the settings.

To specify your short-term tape-based recovery goals

  1. In the Retention range box, type or select how long you need your backup data available. You can select a retention range between 1 and 12 weeks for short-term tape-based protection.

  2. In the Frequency of backup box, select how often you want to back up your data. You can select a backup frequency of daily, weekly, or biweekly depending on your retention range.

  3. In the Backup mode box, select your backup type. For tape-based backup, instead of recovery points, you configure your type of backup as follows:

    • Full and incremental backups. (Available only when you select a daily backup frequency.)

      If you select this backup type, the retention range will be a maximum of one week longer than the one you specified, because of a dependency between full and incremental backups.
    • Full backup only. For more information about full and incremental backups, in the DPM Planning Guide see Planning Protection Groups.

  4. Select your daily backup schedule as follows:

    • Full backup on. When you select daily full backups, you specify the time. When you select weekly or every two weeks, only full backup is available. You specify the day and time.

    • Incremental backup on. (Available only when you select daily full and incremental backups). You specify the day and time for the full backup and for the incremental backup.

  5. Select from the following performance options:

    • Select Compress data if you want to enable data compression on tape.

    • Select Encrypt data to encrypt the data before it is written to tape.

    • Select Do not compress or encrypt data if you do not want DPM to perform data compression or encryption.

  6. Click Next.
