Incremental backups are useful in reducing backup time but they increase restore time objective (RTO). During restore, the Backup Administrator needs to restore a full backup and then apply a number of incremental backups to restore at the desired point-in-time. RTO is improved by synthesizing VMs in the backend. The synthesize process recreates a full VM from its incremental backup and last full or synthetic-full backup.

In this Knowledge Sharing article, Anupam Chakraborty, Sunil Yadav, Soumen Acharya, and Tushar Dethe describe the technology behind backup proxies and how to control backup time in Hyper-V standalone or cluster environments. After the administrator has backed up the virtual machine, what is the guarantee that the backup is consistent for the application running inside the virtual machines?

This article also describes how the partial writer feature of Volume Shadow Copy Service helps to back up healthy VMs and logs unhealthy VMs. Also discussed is how EMC NetWorker integrates with Data Domain to ensure optimal storage utilization.
