What is the Difference Between Backup and Archive?
The two processes work independent of each other. You can both archive and backup a file; however, how the TSM server handles the file is very different for backup and archive. The backup process is used to save data that is being modified frequently. The backup strategy allows you to save different versions of the same file. Should the present file become corrupted or inaccessible, you can restore to a previous version of a backed up file. Your storage policy sets a backup limit on how many versions of each file are kept on the TSM server. When that backup limit is reached, the next backup process will overwrite the oldest version of a file with the new backup version to keep within the backup limit. Backed up files can be restored to the user’s computer by using the RESTORE button on the TSM GUI. Archiving is a one-time snapshot of a file or object in its present state. There is no versioning strategy with the archive process. Archive is generally used for long-term retention of data
