Storage Snapshots for Rapid Recovery

Protect volumes with point-in-time storage snapshots for rapid data recovery

DataCore Hyperconverged Virtual SANの特徴

  • Supports stringent Recovery Point Objectives (RPOs) without compromising business productivity
  • Comprehensive data protection for broad range of applications, hypervisors, and operating systems
  • Integrate seamlessly with popular 3rd party backup and recovery tools
  • Trigger from Microsoft VSS-compatible applications and VMware vCenter
  • Synchronize snapshots across groups of virtual disks
  • Save snapshots in lower cost storage without taking up space on premium devices optimizing storage efficiency
  • Provide “live” copy of environment for analysis, development and testing
  • Eliminate back-up windows
  • Recover quickly at disk speeds to a known good state
ストレージスナップショットバックアップの図
As data is written to the production volume, before the write is committed in production, a copy of the original block is copied to the snapshot volume. This will maintain the original state of the production volume in the event that a rollback back is necessary.

Ever have an application upgrade go bad?

Most have experienced this situation and wished that it could be undone. SANsymphony makes this wish come true through point-in-time volume snapshots.

These snapshots can be used to revert a volume back after a failed upgrade, mounted to a backup server for backup operations, or used to offload data processing operations to a different set of disks.

Snapshots can be leveraged in two ways.

The first is a differential snapshot. This type allows for the volume state to be instantly captured and made available for use. The second is a full snapshot. This type makes a full block copy of the volume to a separate virtual volume (and separate pool if necessary).

スナップショットバックアップは、VSSとも連動しています。VSSは、Windowsアプリケーションサーバーにコマンドを発行して、すべての入出力を静止およびフラッシュすることで、スナップショット前のボリュームの一貫性を確保します。

Integrated with Popular Backup / Recovery Tools

DataCore works with popular 3rd party backup products to simplify end-to-end data protection and ensure rapid data recovery at a granular level.

Veeam、Commvault、Microsoftなどの企業の製品は、DataCoreオンラインスナップショットを利用して、さまざまなアプリケーション、ハイパーバイザー、オペレーティングシステム、ストレージデバイスのバックアップを一元化しています。これらのソリューションを組み合わせることで、バックアップをホストからオフロードし、アプリケーションへの影響を最小限に抑えることができます。その結果、ビジネスの生産性を損なうことなく、より厳格な目標復旧時点(RPO)を達成するために、バックアップの頻度を上げることができます。

Many of the steps typically necessary to coordinate snapshots for backups have been automated so they can be scheduled at regular intervals without manual intervention.

In addition to storage snapshots, DataCore offers Continuous Data Protection (CDP) for especially critical volumes. This option rolls back data to points in time between daily backups to quickly reverse the effects of malware, data corruption and user errors. It can also be used to repeat a missed backup.

Integration with backup / recovery tools complements DataCore’s “zero downtime, zero touch” high availability storage solution, and helps organizations adhere to the 3-2-1 rule:

  • Maintain at least 3 copies of your data
  • Store them in 2 different formats
  • Keep 1 copy off-site
