Absolute

Use the absolute option with the incremental command to force a backup of all files and directories that match the file specification or domain, even if the objects were not changed since the last incremental backup.

This option overrides the management class copy group mode parameter for backup copy groups; it does not affect the frequency parameter or any other backup copy group parameters. This option does not override exclude statements, so objects that are excluded from backup are not eligible for backup even when the absolute option is specified.

Important: Before you use the absolute option, consider the following effects that this option can have on backup and Tivoli® Storage Manager server operations:

Backups consume more server storage and database resources.
Backups consume more network bandwidth.
Server operations, such as inventory expiration, storage pool backup, storage pool migration, reclamation, and node replication, require more time to complete. Data deduplication might help mitigate some of these effects, but it does not avoid the processing that is required to reconstitute the deduplicated data back to its original form when the storage pool is migrated or backed up to non-deduplicated storage.

This option is valid only as a command-line parameter for the incremental command when you are performing the following operations:

Full or partial progressive incremental backups of file systems or disk drives.
Snapshot differential backups when createnewbase=yes is also specified.

To force a full backup of a file system that uses journal-based backup, specify both the nojournal and absolute options on the incremental command.

Windows operating systems During a domain incremental backup, where systemstate is specified as part of the domain, the absolute option does not force a full backup of system state objects. To force a domain incremental backup operation to create a full backup of system state objects, you must add systemstatebackupmethod full to the client options file.

To use the absolute option on scheduled incremental backups, the Tivoli Storage Manager server administrator must create a separate backup schedule that includes the absolute option on the schedule’s options parameter.

Supported Clients

This option is valid for all clients as a command-line parameter for the incremental command. This option cannot be added to a client option set on the Tivoli Storage Manager server.
