Snapshots create an instant point-in-time picture of workloads. This allows for the ability to roll back to a previous instance in the event of a hardware failure, failed software upgrade, vm bluescreens, etc.
Snapshots/Restores can be done at various levels:
- Cloud (entire system)
- Tenant
- Virtual Machine
- Individual vm disk and/or NAS volume
- Cloud snapshots, when synchronized to another VergeIO system can be considered 'warm standby' for Business Continuity/Disaster Recovery (BC/DR) planning
- Recover a clone copy of a VM to perform upgrade testing
- Are branched against the initial data blocks, minimizing additional storage consumption
- Quickly revert an entire physical or virtual environment to a previous state, e.g. rapid recovery from a cryptolocker attack
- VergeIO architecture allows for rapid restores from snapshots by removing the need for collapsing disk images
- Providing disk images are not set to quiesce, snapshots are taken instantly by simply updating or adding a pointer to a data block during that point in time
