How SureBackup Works

For SureBackup, Veeam Backup & Replication uses a regular image-based backup. During recovery verification, Veeam Backup & Replication performs the following actions:

  1. If the SureBackup job is configured to perform malware scan, Veeam Backup & Replication scans data of the machines from the application group with antivirus software.
  2. Veeam Backup & Replication publishes the machines from the application group and the machine under verification in the isolated environment — virtual lab. Machines are started directly from compressed and deduplicated backup files that reside in the backup repository. To achieve this, Veeam Backup & Replication utilizes the Veeam vPower NFS Service.
  3. Veeam Backup & Replication performs a number of tests against the machines in the application group and machine under verification: heartbeat test, ping test and application test.
  4. If the SureBackup job is configured to validate backup files, Veeam Backup & Replication performs a cyclic redundancy check for the backup file from which the machine under verification is started and, optionally, for backup files from which the machines in the application group are started. The backup file validation is performed after all verification tests are complete.
  5. When the recovery verification process is over, Veeam Backup & Replication unpublishes machines and creates a report on their state. The report is sent to the backup administrator by email.

Veeam SureBackup – Automatic Recoverability Verification for VM Backups 

During verification, a backed-up machine image remains in read-only state. All changes that take place when the machine is running are written to redo log files that are stored on the datastore selected in the virtual lab settings. When the recovery process is complete, the redo logs are removed.

To perform recovery verification, you need to create the following objects:

  1. Application group. During recovery verification, the verified machine may need to be started with a group of machines on which it is dependent. The application group enables full functionality of applications running inside the machine and lets you run these applications just like in the production environment.
  2. Virtual lab. The virtual lab is the isolated virtual environment in which the verified machine and machines from the application group are started and tested.
  3. SureBackup job. The SureBackup job is a task to perform recovery verification. You can run the SureBackup job manually or schedule it to run automatically by schedule.
