BACKUP is a utility for creating file backups - copies of file sets that preserve file metadata. Backups can be used to revert from ODS-5 to ODS-2.

Save Sets

A save set is a type of file created by the BACKUP utility that stores files and metadata. It can only be opened and interpreted by the BACKUP utility. Here is a listing of a backup saveset:
