Tiered Data Protection for Business Continuity

Traditional backup strategies present challenges like long recovery times or extraneous storage consumption. Your business needs a smart backup strategy to effectively protect against all threats and keep operations running smoothly.

Resilient backup with optimum data protection

Tiered data protection for deployment flexibility

Safeguard business data for any kind of IT infrastructure.

  • SHA

    Maximize uptime with high-availability clustering

    Combine two servers into a high-availability cluster, so data and applications remain accessible when local hardware malfunctions occur. Automatic fail-over allows work to continue smoothly – without the IT admin’s having to rush to the rescue immediately.
  • Snapshot

    Quickly recover from accidents with snapshots

    Capture point-in-time snapshots, so you can go back in time and roll back from disasters almost instantly. Thanks to self-service file restoration, employees can even recover accidentally deleted files themselves without bothering the IT admin.
  • Replicate the snapshots

    Defend against natural disasters with off-site replication

    Replicate snapshots to a remote Synology NAS so hot data is mirrored off-site. If the primary server in the main site is affected by a natural disaster, you can continue operations by quickly switching over to the secondary site.
  • Hyper Backup

    Efficiently archive data with multi-version backup

    Retain historical archives by backing up data to a wide range of destinations, including external drives, remote Synology NAS, or even your preferred public cloud service. Advanced features like encryption or deduplication keep sensitive data private and reduce storage consumption.

Ready for your virtualized environment

Ensure business data and virtual machines in iSCSI LUNs remain safe and available in the event of disaster.

  • Take snapshot as frequently as 15 minutes for iSCSI LUNs, instantly protecting the storage for virtualization.
  • Application-based snapshots for virtual workloads running on VMware and Hyper-V ensure data consistency on virtual machines.
  • The support of VMware Site Recovery Manager facilitates the recovery process by starting disaster recovery directly via VMware vCenter Server.
