Overview

With the forever-incremental backup repository, a full backup is made initially. After that, only incremental backups are made, accumulating the changed data blocks without any subsequent full backups. Appropriate blocks are backed up and block references are included in recovery points indicating related blocks that are necessary to restore the corresponding VM as of the specific point in time. The forever-incremental backup repository type is recommended for simple disk-based DAS and NAS backup destinations.

For the incremental-with-full-backups repository, the starting point is creating a full backup file. On consequent backups, data blocks that have changed since the previous backup are stored in incremental backup files. To start a new incremental chain, a new full backup is made at the time defined in the job settings. The previous incremental chain cannot be deleted until the new incremental chain is started. The incremental-with-full-backups repository type is recommended for enterprise-scale deployments where high reliability and top performance are major concerns, and deduplication appliances are widely used.
