Use the replication feature to perform incremental replication from a VM backup or database backup to a synced copy of the source. The replication operation continuously applies changes from the source backups since the last sync point. You can use the following backup types for replication:
-
Traditional backups
-
Auxiliary copies
-
Backup copies
The replication feature performs the following procedures:
-
Initiates the replication automatically after a backup completes, or on a schedule.
-
Copies the backup data to remote disaster recovery (DR) sites with deduplication to minimize the wide area network (WAN) traffic. Replication then runs at the DR site.
Disaster Recovery Benefits
Use replication to create and maintain recovery sites for virtual machines, file systems or databases. Meet RPO objectives by specifying the frequency that the software performs backup operations. The replication feature has the following benefits:
-
Replication minimizes the impact on production systems CPU and I/O by using the backup data for replications. This method avoids the need to read the source database again for replication.
-
Replication is hardware agnostic so there is no need to reproduce the original hardware environment at the recovery site.
-
Replication minimizes the data that is transferred over the WAN by sending incremental updates of the data to keep the source and destination in sync. Additionally, the data uses deduplication and compression to reduce traffic.
-
Replication minimizes the RTO because it automatically validates the backups and you can specify the new network connections.
