With legacy vaulting, the most recent backups of a client are synchronized to the vault. When a new master or full backup is created, this backup is then vaulted, and the prior vaulted backup removed. With replication, previously replicated backups are retained on the target, as long as there is room on the system and the backups are within the retention and legal hold limits set on the target. See About retention control for details.
A system’s installation type governs how retention can be configured on a given system. For a description of each installation type, see Installation types and replication. Retention settings can be configured for the following installation types:
• Local backup system to manage retention of backups run on the system.
• Replication target to manage retention of backups replicated to the system.
• Local backup system and replication target to manage retention of both backups run on and replicated to the system.
Retention settings cannot be configured for legacy vaults as vaulted data is not retained.
