Hyper-convergence + backup software = scale-out backup nodes
Summary
Instead of streams of data from many different servers, backup software was able to use an application programming interface (API) provided by the hypervisor maker.So there was no need for client software on each virtual server to track updates and differences, making the backup deployment process much easier.Instant restore is a feature that couldn’t be implemented without an internal file system or a process to create synthetic views of VMs from backups.Most backup solutions use “monolithic” database software like SQL Server or MySQL that don’t scale easily across many nodes.Many solutions also provide the ability to geographically disperse nodes, creating a multisite configuration that would have been much more complex to manage with traditional backup.
