What is an Incremental Backup?

An incremental backup of a storage space backs up only those pages that have been modified since the last backup of the storage space. ON-Bar supports the following types of backups:

• Full backups, also called level-0 backups
• Incremental backups of full backups, also called level-1 backups
• Incremental backups of incremental backups, also called level-2 backups

Use the -L option to the ON-Bar backup command to select the level of backup. By default ON-Bar performs a level-0 backup.
