NetApp Snapshot is a data replication software that works through snapshot copies, crucial for the recovery of data. These copies are used as safe points for rollback before upgrades or patches. NetApp Snapshot provides prompt data replication which is also highly space-efficient, and provides users with the full management and control of their data and its copies. Through the various solutions the Snapshot technology has introduced, companies receive enhanced stability, functionality, and performance, as well as storage efficiency.
NetApp Snapshot uses two types of snapshot technologies to handle data replication: Copy on Write (COW) and Redirect on Write (ROW). The COW technologies make a copy of the original information and then only after the replication process is completed does the system overwrite the modified data into the original blocks. In contrast, ROW redirects the snapshots to new storage blocks, updating pointers to those blocks, which always point to the original location. When NetApp Snapshot combines the two technologies, it allows customers to save storage efficiency by way of deduplication and compression.
NetApp Snapshot Features
NetApp Snapshot’s valuable features include:
-
Data replication stability: Every NetApp Snapshot copy is an immutable, static copy, giving organizations the opportunity to create consistent backups from their storage system while applications are running.
-
Performance impact: The performance of NetApp's systems that store NetApp Snapshot aren’t affected. The actions of creating or deleting a Snapshot copy also don't greatly impact the performance of the systems where they are located. NetApp’s storage can be used for data replication, backup, and archival even if a company is using another storage system.
-
Storage scale: Another beneficial feature of NetApp is the volume of storage, which supports 255 Snapshot copies. This provides users with the opportunity to perform frequent data replication, thus creating current versions of their data.
-
File recovery: The above-mentioned features allow for the creation of backup for recovery purposes. They also provide\ the opportunity to copy backups to offline storage as well as to create an archive for them.
-
Storage utilization: The option for utilization of storage allows NetApp Snapshot users to benefit from storage volumes similar to those of active file systems. The software works through block increment, which limits the interval of time between added blocks of Snapshot copies, thus creating more efficient storage.
NetApp Snapshot Benefits
The benefits of using NetApp Snapshot include:
- Ability to create instant data replication while applications run
- Up to 255 data replicas available
- Various tools for full-package coverage, including SnapManager, SnapProtect, SnapMirror, SnapRestore, and SnapVault
