Veeam Backup & Replication lets you perform Snapshot Orchestration — build a snapshot chain on primary and/or secondary storage arrays. To create snapshots on storage arrays, you must run a snapshot-only job.
The snapshot-only job is similar to scheduling automatic snapshot creation in the storage management console. A snapshot-only job does not create Veeam backup files on the backup repository. It creates only storage snapshots on the storage system by a schedule that is defined in the job settings.
Depending on the backup job settings, the created snapshots can be application-consistent or crash-consistent.
