Use

To allow you to backup at a higher speed, you have the option of backing up to a number of media in parallel. For this purpose you define a group of Structure linkparallel media under a single medium name. A backup which is going to be made to a number of media simultaneously should have this medium name assigned to it.

The maximum number of parallel media in a group is determined by the value set in the parameter MAXBACKUPDEVS.

When you restore, you can import the data from this type of backup in parallel. The value set in the parameter MAXBACKUPDEVS also determines from how many media you can import in parallel.

Procedure

  1. Select BackupMedia ® New ® Media Group.
    In the     Backup - Media Manager window, the system creates the media group New Group in the form of a directory whose media type is Parallel.
  2. Give the media group any name. You can change this name at a later stage using BackupMedia ® Rename.
  3. Double click on the directory to open it.
  4. Then define each individual medium in the media group:
    Choose BackupMedia ® New ® Medium.
    Select General in the     Backup - Medium window and make the following entries:

Name:

Freely definable name to identify the medium

If you want to perform a backup or a restore using one of the external backup tools ADSM, NetWorker, Backint for Oracle, or Backint for SAP DB, ensure that the name of the medium starts with ADSM, NSR, BACK, or BACK (Backup with External Backup Tools).

Location:

Define the location to which backups are to be made.

With files and pipes, we recommend specifying the absolute path to the backup medium.

Device Type:

Select the type of backup medium:
File, tape, or pipe.

If you back up the log to a file, the Database Manager GUI automatically generates version files. An automatic Structure linklog backup cannot be made to tape.

If you are saving with external backup tools, enter Pipe as the Device Type.

When you are backing up to tape, you need to set the device driver correctly under the UNIX operating system. Use rewind tapes for backups. On Windows NT/Windows 2000 operating systems, the system sets the device driver automatically.

Backup Type:

Select the type of backup you want (full or incremental Structure linkdata backup, interactive log backup, or automatic log backup)

Select Extended in the Backup - Medium window and make the following entries:

Size:

Size of backup medium

Overwrite:

Select the Overwrite field when you want to use the overwrite mode for the medium (only possible with medium type File).

Autoloader:

Select Autoloader to use a tape device with autoload facilities (Backups to Automatic Tape Loader).

OS command:

You can enter any operating system commands appropriate for backup to tape now.
