Media

The term medium describes a data carrier on which backed up data is stored and preserved in case of an emergency. It contains tapes in tape devices, hard disks as changeable at USB connection or virtual media as directories, which are located on permanently connected hard disks. SEP sesam uses only media that are registered in media archives. The first window shows shows a list of media, containing all media prepared for use with SEP sesam.

You can migrate media from the source media pool by clicking Migrate option.

The media table columns can be arranged in a particular order by dragging & dropping with the left-mouse button on the column header. You can select which columns should be displayed. These settings will be stored in the users local Java profile. If you right-click on a column header the options such as Label, Barcode, Loader, Write Protection, Media EOL, etc., are shown.

Properties 1

Double-clicking a relevant media opens its properties where you can edit the media's settings.

• Media pool: Name of the media pool containing this media (uneditable).
• Write protection: This switch is set by SEP sesam itself, and can only be changed manually. When toggled to On, the medium is not used for backups even if EOL (End-Of-Lifetime) is expired.
• Backup day: Date of the backup day (uneditable).
• Locked until: It is automatically set with values from the media pool while the backup procedure is running. It can be adjusted individually.
• Drive: Drive in which the media was last used (uneditable).
• Next media: In a big backup session, more than one medium can be used. This value indicates in what position this medium was used during the backup (uneditable).
• Media type: Media type of the medium, e.g., LTO_Tape (uneditable).
• Loader: Numeric value of the loader, which handles the media pool.
• Slot: Number of the slot in the loader. It is better to use an archive adjustment.
• Encrypted: States if the medium is encrypted or not (uneditable).
• Change Password: You can change the encryption password for the existing media.
• OK: Save the changed media parameters in the database and return to the start screen.
• Delete Media: Removes the data set from the archive and closes the entry mask.
• Apply: Save of the changed media parameters in the database. Entry mask can be used for further changes.
• Cancel: No action and return to the start screen.

Properties 2

• Label: SEP sesam label of the medium, used for media identification.
• Barcode: Barcode information of the medium.
• Occupancy: Shows the current occupancy of the medium in percentage (uneditable).
• EOM: End Of Medium states if there is still space left on the medium (uneditable).
• Error count: Accumulated count of errors of the medium on the drive.
• Error delta: Displays the difference of errors compared to the last usage.
• Use count: Counts the initialization of the tape (uneditable).
• Last SEP sesam message: The last SEP sesam system message.
• Note: Optionally, add additional comment.

Savesets and Media Actions properties

As of v. 4.4.3 Beefalo, the Savesets and Media Actions tables have been enhanced with the new options, e.g., Auto update, Filter, etc.

The Savesets lists all currently saved backups of the medium. You can show or hide columns by clicking a right-mouse button on the column title.

The Media Actions lists all media events, such as the introduction in the SEP sesam environment, initialization for backup, readability check, etc.

Adding a new medium

From Media -> Introduction you can insert a new medium into the media-archive.

• Media pool: Name of the media pool to which the medium is added. Select one of the configured media pools.
• Storagepool: If the selected media pool has storage pools assigned to it, you can select it here.
• Drive: Selection of drive in which the media must be initialized (depends on the selected media pool).
• Type, Device, Client, Loader: (uneditable)
• Media type: Selection of media type (pre-selection depends on the drive type).
• Handling of unknown SEP sesam Media: It affects SEP sesam's bahavior, if a SEP sesam tape label is recognized on the medium, but it is not found in the database. This is the case, when a tape was removed or there is tape from another SEP sesam installation. Empty media or media written by other applications are always re-labeled. However, media, which are already in the database, will never be re-labeled.

	Note
	Utilzation of unknown SEP sesam Media alerts the user that a SEP sesam tape or medium has been entered, but is not entered in the SEP sesam database. This can happen when a tape was erased or if a tape was entered from another SEP sesam installation. Empty tapes or tapes from other programs/applications will always be overwritten. Media found in the SEP sesam database will never be overwritten.

• Accept without initialization: Takes over the medium with the given label in the SEP sesam database. If the related media pool does not exist, it will automatically be created.
• Overwrite: Overwrites all media entered to the target media pool that are not recognized by the SEP sesam Server and assign a new media pool label to them.
• Label number: Treats the media as empty and writes a new label on the tape.
• Automatically assign next number: SEP sesam automatically assigns the label number for the media that should be added. By this process, the highest existing numeric value within that media pool is increased by one.
• Take label from media: Creates the last five digits according to the editable text box.
• Start: Start insertion of new media.
• Cancel: Close screen, no insertion.
