To build a backup solution that is scalable, cost-efficient and allows multiple disaster recovery scenarios, then switching to a hybrid cloud backup strategy is best.
Hybrid solutions work in conjunction with your existing backup applications and policies. Local on-premise data can remain local if required and still have the flexibility of expanding onto cloud storage should you require additional capacity. Utilizing this cost-effective storage means you can store a full copy of all your backups on the cloud in the event of a site disaster.
