Taking VMware vSphere snapshots can produce a serious burden on virtual machine (VM) performance, and it can take considerable effort by administrators to overcome this technical challenge and meet the required SLAs.
Veeam dramatically improves this process, providing built-in integration with your production storage, leveraging storage snapshot functionality to reduce the impact on the environment from vSphere snapshot removal during backup and replication.
Don’t be stuck with once-a-day backups for I/O intensive workloads—make backups and replicas as often as every 15 minutes!
Storage snapshots can be taken frequently with minimal impact to the production environment, but this can’t be your only backup solution. What if storage itself goes down, or gets corrupted? Even with storage-based replication, you need to take your data out of the single fault domain. This is why many customers prefer to additionally make true backups stored on different storage.
Veeam combines best of both worlds with vSphere snapshots for application-consistent backups and storage snapshots for fast recovery point objectives (RPOs). Now you can:
Run backups at any time and frequency, dramatically improving achievable RPOs
Speed up the process—back up from storage snapshots up to 20x faster than with competitive solutions
Dramatically reduce the impact of backup activities on your production environment
Veeam Backup & Replication works with HP and NetApp storage products to create backups and replicas from storage snapshots in the following way. The backup/replica job:
Analyzes which VMs in the job have disks on supported storage.
Triggers a vSphere snapshot for all VMs located on the same storage volume. (As a part of a vSphere snapshot, Veeam’s application-aware processing of each VM is performed normally.)
Triggers a snapshot of said storage volume once all VM snapshots have been created.
Retrieves the CBT information for VM snapshots created on step 2.
Immediately triggers the removal of the vSphere snapshots on the production VMs.
Mounts the storage snapshot to one of the backup proxies connected into the storage fabric.
Reads new and changed virtual disk data blocks directly from the storage snapshot and transports them to the backup repository or replica VM.
Triggers the removal storage snapshot once all VMs have been backed up.
As the result, VMs run off snapshots for the shortest possible time, while jobs obtain data from VM snapshot files preserved in the storage snapshot. As the result, VM snapshots do not get a chance to grow large and can be committed very quickly without overloading production storage with extended merge procedure, as is the case with classic techniques for backing up from VM snapshots.

Recovery from storage snapshots
Backup is nothing without recovery. With Veeam, you can tackle virtually any recovery scenario including granular recovery from storage snapshots.
