Section 6 - Configuring backup Sets

A backup set defines the configuration of a backup routine, such as backup schedule, backup source and encryption setting as well as other options.




6.1.13 Options


    There are three methods for restoring data:






6.1.13.1 Temporary Directory for storing backup files

Back to top


    The temporary directory is used for various purposes, such as storage of temporary spooled file (for database specific backup type), remote file list, local file list, temporary delta file and other files of temporary nature.



    To configure the temporary directory location, click [Change] and browse to the directory path for storing the temporary data.

    For database specific backup type, data files spooled by the latest backup job can be kept by disabling the [Remove temporary files after backup] option.



    Notes:
    Administrators need to pay attention to the maximum file size limitation of different file system format, so that database file can be spooled to the temporary directory.




6.1.13.2 Follow Link

    Follow Link defines whether to follow an NTFS junction point or NTFS symbolic link during backup.






    Menu Items

    Note:
    For local copy backup, only basic retention policy can be applied.

    Skip backing up to Offsite Backup Server

    Checkbox to skip or to perform off-site backup for the corresponding backup set.


    To enable the [Follow Link] option, select the checkbox beside the follow link option.

    Note that system protected junction point such as the Documents and Settings on Windows 2008 server cannot be selected as backup source under the advanced backup source dialog (e.g. there is no select-able checkbox beside system protected junction point).



    To manually select system protected junction points for backup, select the parent directory of the junction point, or enter the corresponding junction point (e.g. C:\Documents and Settings) on the web interface.




6.1.13.3 Enable Volume Shadow Copy

    Action

    Enabled

    Create a snapshot of the data to be backed up for exclusively opened file.

    Disabled

    Do not create a snapshot of the data to be backed up for exclusively opened file. Error message will be shown for files that are opened during the backup process.



    *The availability of features listed above may be service provider dependent. If a feature is not available, please check with your service provider for further details and availability.

    Enabling the Volume Shadow Copy option will allow backup of local files that are exclusively opened during the backup process (e.g. Outlook PST file).

6.1.13.4 Compression

Back to top


    Compression type defines the compression method that the backup application will use during backup (for the corresponding backup set).



    There are 3 compression types available for user to select:




    By default, newly created backup set is configured to uses [Fast] compression type.

    Note:
    The [Compression Type] option is only available for OBM version 6.9 or above connecting to backup server version 6.9 or above (please consults your service provider for details).

    For existing backup set created in previous version, the compression type will be [Normal].




6.1.13.5 Transfer Block Size

Back to top


    Transfer block size defines the block size that the backup application will use to transfer your backup data to the backup server.



    Note that certain firewall applications or proxy servers may block out-going network traffic with large block size for security reasons.

    If you are in a network with this type of restriction, please lower the transfer block size value

    To change the transfer block size of any backup set, select the [Options] tab on the left panel and then select the corresponding block size from the [Transfer Block Size] dropdown menu.

    Press the [OK] button, and save before exiting out of the backup application.
