Method 1: Using image backups with file system incremental backups

Edit online

This topic lists the steps to perform image backups with file system incremental backup.

About this task

Procedure

  1. Perform a full incremental backup of the file system. This establishes a baseline for future incremental backups.
  2. Perform an image backup of the same file system to make image restores possible.
  3. Perform incremental backups of the file system periodically to ensure that the server records additions and deletions accurately.
  4. Perform an image backup periodically to ensure faster restore.
  5. Restore your data by performing an incremental restore. Ensure that you select the Image plus incremental directories and files and Delete inactive files from local options in the Restore Options window before beginning the restore. During the restore, the client does the following:

Results

  • Restores the most recent image on the server.
  • Deletes all of the files restored in the previous step which are inactive on the server. These are files which existed at the time of the image backup, but were subsequently deleted and recorded by a later incremental backup.
  • Restores new and changed files from the incremental backups.
Note: If an incremental backup is performed several times after backing up an image, make sure that the backup copy group of the IBM® Storage Protect server has enough versions for existing and deleted files on the server so that the subsequent restore image with incremental and deletefiles options can delete files correctly.
