Tivoli Storage Manager FastBack for Workstations, Version 6.1.2

Continuous Protection panel of Groups Configuration

Use the Continuous Protection panel to set the maximum space on local storage for backup copies and the maximum versions of backup copies on local storage.

How many versions to keep field

Tivoli® Storage Manager FastBack for Workstations can save more than one backup version of each file. When you restore a file, you can choose which version of the file you want to restore. When the configured number of versions is reached, older versions of a file are deleted. Keeping more versions requires more local storage space, but allows you more choices when restoring a file.

Maximum space for backups field

Specify how much space to use for all backup copies on local storage. When the storage area becomes full, older versions of files are deleted until the storage area is at about 80 percent of the configured maximum. If, after deleting all versioned backup copies, local storage space is still insufficient, Tivoli Storage Manager FastBack for Workstations will delete the oldest non-versioned files.

Note: No warning message displays when the maximum space is reached.

The default space for local backups is 500 MB.

Note: If you try to back up a file which is larger than the space you have allocated for your storage area, Tivoli Storage Manager FastBack for Workstations purges all older versions of your files, and then fails to back up the file. Make sure that the maximum space for your storage areas is greater than the file size limit in the Advanced page of the Tivoli Storage Manager FastBack for Workstations.

Continuous protection level list

Tivoli Storage Manager FastBack for Workstations offers two levels of protection for your files: continuous protection and scheduled protection.

Use this box to select which storage areas to use for continuously protected files.

None
Files are not protected.
Local storage only
Tivoli Storage Manager FastBack for Workstations creates backup copies only on the local storage area.
Remote storage only
Tivoli Storage Manager FastBack for Workstations creates backup copies only on the remote storage area.
Local and remote storage
Tivoli Storage Manager FastBack for Workstations creates backup copies on both the local and remote storage areas. This choice provides the most protection for your files, and is the default choice.

If your continuous protection level includes local storage, Tivoli Storage Manager FastBack for Workstations creates backup copies in the \RealTimeBackup\ folder on the nonremovable drive with the most free space.

Note: The client can specify the drive for local storage, but the central administration console cannot. The central administration console defines a configuration that potentially applies to many clients, and it is possible that not all the target computers have the same hardware configuration. Hence, the central administration console configuration specifies the default drive for local storage, which is the nonremovable drive with the most free space.
