To modify compressions for devices, go to Global Objects -> Backup/Restore Devices
or Backup/Restore Devices at the site level. You can not modify the compression of
a device if it belongs to any backup manager.
Adding and modifying media types
Media Operations contains a set of predefined media types and compressions for
most current tape technologies., which you may add to or modify.
If you add a new media type and you use a supported Backup Manager or XML File
Import interface, Media Operations automatically creates the basic media type. You
must also create compression types for the media. If the new media type does not
match an existing vault slot type, configure a new vault slot type using Global
Configuration Options -> Media Types and Compressions.
Defining media policies
There are three basic types of media policies:
• Media Vaulting Policies, defining how long a medium is retained in a device,
onsite and offsite vault locations.
• Scratch Media Policies, defining premount jobs that manage loading new scratch
media into backup/restore devices and removal of media to be vaulted from the
devices (based on the vaulting policies).
• Server Parameters, defining schedule settings that indicate when vaulting, scratch,
and premount jobs run.
Configuring media vaulting policies
Vaulting policies configured in each site are built on global vaulting policy templates.
You can deploy these policies in a site at various levels to control which media in
that site they affect.
If you modify a template, the changes immediately apply to every vaulting policy to
which the template was originally applied. This saves you modifying the policy
multiple times. Every vaulting policy template is defined in terms of:
• “Media vaulting policy hierarchy” on page 82
• “Basic vaulting policy concepts” on page 83
• “Vaulting templates” on page 83
• “Active vaulting policies” on page 84
• “Defining barcode labeling policies” on page 86
