Incremental Backup

An incremental backup can be one of two types:

• Cumulative Incremental backup

Backs up all files specified in the backup selections list that have changed since the last successful full backup. All files are backed up if no prior backup has been done. These backups occur automatically according to the criteria in the schedule. A complete restore in this instance requires the last full backup and the last cumulative incremental.

• Differential Incremental Backup

Backs up all files that are specified in the backup selections list for the policy that have changed since the last successful incremental or full backup. All files are backed up if no prior backup has been done. These backups occur automatically according to the criteria in the schedule. A complete restore in this instance requires the last full backup, the last cumulative incremental, and all differential incrementals that have occurred since the last full backup.
