The client comprises an enterprise database application. The method identifies tracks of the logically represented volume that have changed since a last incremental backup. For our backup strategy we are using incrementally updated image copies on most Oracle databases. This method can save a lot of time during restore operations, since you don’t need to restore full backup and then apply all the incremental backups, you can either restore the full backup.

An incremental backup is one in which successive copies of the data contain only the portion that has changed since the preceding backup copy was made.
