Tivoli Storage Manager FastBack for Workstations, Version 6.1.2

Use sub-file copy radio button

Set sub-file copy for remote backup copies.

Initially, an entire file is copied to the storage areas. When sub-file copy is turned on, and when the file changes, only the changed information is copied to the storage area. The sub-file copies are saved as separate files on the remote storage.

Sub-file copy can significantly reduce the amount of network traffic. However, sub-file copy consumes more processing resource on your computer. The default setting is to use sub-file copy for files larger than 50 MB. If you need to conserve more network resources, you can reduce the size setting so sub-file copy is not used on even smaller files.

To use sub-file copy to remote storage, you must have a backup copy of your files on local storage. In the General panel of the Groups Configuration, set the Continuous protection level field to Local and remote storage. Then you can set the sub-file backup option.

Check the button to turn on sub-file copy. In the Use sub-file copy for files larger than: field, specify the file size threshold for using sub-file copy. For files larger than this size, only the changed information is copied to the storage area.
