SureBackup is developed to automate and simplify the backup verification process, one of the most crucial parts of data management and protection. It is a feature that allows you to start VMs directly from VM backups in a fenced-off environment and perform backup reliability and availability testing as a routine part of the backup process.
To perform recovery verification testing, you need to create an application group required to verify full functionality of backed up VMs, an isolated virtual lab where VMs should be tested, and a recovery verification job.
•An application group is a group of virtual machines that contains VMs running production applications on which VMs to be verified are dependent. That is, it includes all components and services that should be started to enable fully functional work of VMs you want to test.
•A virtual lab is an isolated virtual test environment where verified VMs with all components required for their proper operation are started and tested. A virtual lab is created using existing resources in your VI environment and ensures secure integrity and functionality testing for backed up VMs.
•A recovery verification job aggregates all settings and policies of a recovery verification task, such as required application group, virtual lab to be used and backups of VMs that should be verified in the created environment.
When a recovery verification job runs, VMs from the application group are published and then started from backups in the required order and remain running while VMs from verified backups are booted and tested.
During verification, a backed up VM image remains in the read-only state — all changes that take place when a VM is running are written to redo log files that are stored on a selected datastore in the production environment. Once the recovery verification process is complete, the redo logs are removed.
When performing recovery verification of VM backups, Veeam Backup & Replication runs VMs directly from backup files without restoring them to a production datastore. This is achieved by utilizing the vPower NFS service — a Windows service that runs on a Windows-based backup repository server and enables it to act as an NFS server. vPower NFS allows Veeam Backup & Replication to mount a compressed and deduplicated backup file as a regular VMDK file directly to the ESX(i) host via NFS, so ESX(i) hosts get transparent access to backed up VMware VM images.
