The Tivoli® Storage Manager FastBack for Workstations client offers three types of protection for your files: continuous protection, scheduled protection, and vaulting.
Continuous protection means that every time a file is saved, a backup copy is created. Hence, the backup copy exactly matches the original file as you last saved it. If you choose to save more than one version of a backup copy, the previous backup copies match the previous versions of your file.
Files that are protected by schedule are copied to the remote storage area on a regular schedule. They are not backed up every time you save them, as are continuously protected files. Hence, scheduled protection yields fewer backup copies. If a file is lost between the time it is saved and the time it is backed up, you are able to restore only a previous version of the file.
E-mail files are protected on a schedule.
If the storage area is unavailable when a protected file is saved, the client notes that the file has changed. When the storage area becomes available, the client makes a backup copy of the most recent version of the file.
