If you have previously passed on backing up to the cloud because of price and functionality, it’s time to take a fresh look. There is now a landscape of affordable options with great features like System Recovery in the cloud. If you are still manually bringing tapes in and out of the Server room, you might be able to rethink that approach without changing your core on-prem backup strategy.
If you are currently leveraging a 3-2-1 approach, 3 copies of the data, 2 local (1 offline) and 1 off site, you can continue to use tapes for your local offline or well protected disk-based solution, keeping them safely housed in the data center, and offload the offsites to the cloud. This will allow you to still be able to recover locally at a fast rate and in a situation where you lose the whole datacenter or region, you can spin up critical servers at your cloud location.
Now, if you are still using a legacy, overnight only backup system, you can still add a cloud destination to your current product set without having to do a forklift upgrade. This makes it possible for a legacy environment to get most of the cloud benefits that a modern backup environment may have available.
The arguments for management are getting an offsite disaster recovery environment that is scalable and affordable. This will reduce the worry and cost of a full-scale outage. The argument for IT is to more easily control the offsite environment while adding the ability to recover in the cloud and removing the need for managing physical gear previously associated with getting data offsite.
