This section describes deduplication, a mechanism designed to eliminate data repetition by storing identical data in archives only once.
Starting with v11.7, Acronis Backup uses a new deduplication algorithm. The information in this section is effective for the case when v11.7 agents back up to deduplicating vaults created on v11.7 storage nodes. When a new agent backs up to an old vault or an old agent backs up to a new vault, the old deduplication algorithm is used. To apply the new deduplication algorithm to old backups, you need to import the backups into a newly created vault.
