Veeam CDP and Application consistency

Veeam CDP (Continuous Data Protection) is one of my best new feature in Veeam Availability Suite 11 (Veeam Backup & Replication v11), it provides better SLAs for end-users by using new VMware technology. Veeam CDP (without snapshots) – VMware continuous data protection to reduce RPOs from minutes to seconds. It leverages VMware’s VAIO framework to reliably intercept and redirect VM I/O to the replica without a need to create standard VM snapshots. Maintain consistency between applications and data for precise and predictable recovery is the challenge of this new functionality! Veeam rose to it with application-aware processing and the same Disaster Recovery process as Replication job/Failover. Really powerful…

Continuous Data Protection (CDP) allows enterprises to automatically capture and track data modifications, saving every retention created data locally or at a target repository. With little-to-no production overhead, incremental writes are replicated continuously and saved to a journal file. CDP’s restore to a point in time also allows administrators to restore data to any point in time with a remarkable granularity.

Maintain consistency between applications and data is essential. More details: Microsoft VSS & Veeam B&R

Note: The CDP filter is installed cluster-wide and not per host in order to keep consistency in case a host is being removed or added from and to the cluster. The filter driver is a VIB installed in every host.

With Veeam CDP, the restore process is a little bit different compared to standard replication and the VM can be recovered to a specific state identified in the screen with a different color:

  • Crash-consistent: The data is in the identical state it was in at the time of the backup,
  • Application-consistent: Backups also capture all data in memory and all transactions in process.
