For customer with more demanding data availability requirements are encouraged to investigate third party solutions for backing up VMware VMs by companies like Veeam and Symantec.
Veeam describes their product as a ”powerful, easy to use, and affordable data protection for virtualized applications and data on VMware vSphere unifying backup and replication in a single solution.”
We highly recommend this product to protect enterprise-grade data.

Another enterprise-level VMware backup solution provider worth investigating is the Symantec offering “Backup Exec Family”.

Note: Redbooth Private Cloud does not support installation of third-party backup agents (the Veeam solution requires no agent), so any third-party solutions you do use will need to be agent-less.
