Backing up data

With Backup and Restore Manager, you can create backup copies of data on disk or tape. The source data can reside on CMS minidisk, SFS, BFS, FBA images, or CKD images. Direct the output to disk, tape, or twin or dual tapes as needed.

Complete these steps to back up your data:
  1. Determine the type of backup that you want to perform. For more information, see Backup types.
  2. Select the data that you want to back up. For more information, see Selecting data for backups.
  3. Determine how often to back up the data. Typically, you back up data when the data changes. For example, when you update a file or you create a new file. Consider the requirements that are specific to your site, if any. For more information, see Scheduling backups.
  4. Choose the method that you want to use to back up data:
    • Job templates that you use to create backup jobs. (This is the recommended method.)
    • Application code that you develop (based on application code examples) to back up one or more files.
    • Backup routines that you invoke from your REXX applications.
    For more information, see Methods of backing up data.
