Backup and restore concepts

HCL OneDB™ provides two utilities for backing up and restoring database server data. Both utilities back up and restore storage spaces and logical logs. However, they support different features and it is important to know the differences. These topics explain basic backup and restore concepts for HCL® OneDB database servers and compares the ON-Bar and ontape utilities.

ON-Bar backs up and restores storage spaces (dbspaces) and logical file, by using a storage manager, whereas ontape does not use a storage manager.
