The following features for ActiveImage Protector are as follows.

Volume Backup

Step 1: Select Backup Source

link

Use one of the following operating procedures to select a backup source. Click a radio button to specify the backup type and the backup source.

link

  • Disk: Select if backing up the entire physical disk (to include all volumes).

  • Volume: Select if backing up the specified volume only.

  • Volume Group (VG): Select if backing up the specified volume group.

  • Logical Volume (LV): Select if backing up the specified logical volume.

  • LVM: Select if backing up the specified LVM. Please select a volume group (VG) and related disks.

After configuring the above settings, click [Next].

Step 2: Select Destination

link

Select a destination storage and configure the settings.

  • Task Name Specify a name for the backup task.

  • Destination Folder Specify the destination folder for the backups. The created backups are saved with a unique name in a sub-folder created under the specified destination folder.

    You are not allowed to edit the unique backup image file name.

    When specifying cloud storage as the destination, please refer here for the details.

  • Comment
    Add a brief description in the [Comments] textbox to define for the created backup.

  • Destination Isolation Option
    Disconnects access to the backup image storage drives after backups complete. Upon completion of the backup task, the specified destination storage becomes inaccessible.

    The combined use of the Destination Isolation feature that includes a post-backup process is not supported.

  • Compression Enabling compression reduces storage requirements by further compacting the backups. Begin by checking the [Compression] box, then selecting the desired type of compression.

    • Deduplication Compression: Select one of the three levels of deduplication available.

      • Level 1 - Deduplication is performed at the highest level. This level of compression may increase the overall backup processing time but achieves the most tightly compressed backups.

      • Level 2 - This preset level provides the best balance between process time and compression performance. (This is the default setting).

      • Level 3 - The backups will be generated at a lower compression rate and deduplication requires less backup processing time.

        Change temporary file folder: Set the location for deduplication to process temporary files.

        The maximum size of the temporary file folder will be 1% of the used space of backup source.

        It is recommended to specify a folder on an SSD that delivers fast read and write speeds.

    • Standard Compression: The dropdown menu provides two levels of standard compression.

      • Fast - Backup processing time and storage requirements are at an optimum.

      • High - The backup task will place a higher demand on system resource usage and an increase in processing time but the result is a smaller backup image.

  • Password Protection Password protect the backups by assigning a unique password. This ensures that password input is required for mounting, exploring, or restoring any of the contents of the backups.

    • RC5 - An early encryption standard with a variable block size, key size and number of rounds. Selecting RC5 encryption provides a faster encryption processing speed.

    • [AES 128 bit] and [AES 256 bit] - A stronger encryption method than RC5 with a fixed block size and a key size of 128 or 256 bits.

Precautions when using Deduplication Compression in boot environment

When backing up in boot environment by using Deduplication Compression feature, please be aware of the following.

  • The boot environment boots up by reserving the minimum required memory area on host for booting up the system.

  • When using the Deduplication Compression feature, a temporary file folder is required. The maximum size of the temporary file folder will be 1% of the used space of backup source or less.

  • By default, a folder on memory deployed on boot environment is specified as the temporary file folder.

Due to the above described conditions, a backup task using Deduplication Compression fails in error when processing large amount of data.

When executing backup task using Deduplication Compression in the boot environment, verify that the specified temporary file folder has sufficient available space.

Execute a backup task after specifying an additional storage for temporary files

  1. Please connect an external storage device such as USB device to the system you run a backup task. Please make sure the external storage has available space more than 1% of the backup source system.

  2. Insert the boot environment media and boot up boot environment.

  3. Launch Backup Wizard and select [Deduplication Compression].

  4. Select [Change Temporary File Folder] or click [< Advanced Setting].

  5. Please select the folder in the external storage connected with the above step 1 for the temporary file folder for Deduplication Compression.
