3 possible ways: 1. backup via your virtualization environment (backup the vm at whole or just a snapshot, this ist not really a backup but works great) 2. use a backup software from inside your virtual machine(s) or a backup suite with agents to backup more systems the market is full of possible solutions 3. use a specialized software for your virtualization environment like that: https://www.vmware.com/products/datacenter-virtualization/vsphere/data-protection.html
you may have tree ways:
1. backup via your virtualization environment (backup the vm at whole or just a snapshot, this ist not really a backup but works great)
2. use a backup software from inside your virtual machine(s) like "tar" under Linux or a backup suite with agents to backup more systems the market is full of possible solutions
3. use a specialized software for your virtualization environment like that: https://www.vmware.com/products/datacenter-virtualization/vsphere/data-protection.html
(4. write your own backup script from inside the systems, I done this long time ago for my former company for Linux and Windows in less than 20hr each ;) )
We use Veeam in my environment for our mission critical VMs. Once it's working you can set and forget. My understanding of it is that it schedules snapshots of your VMs and then moves your "backup snapshots" to an external or network medium. I'm sure there are a lot of products out there that fill this niche. What I do know is that snapshots won't do anything for you if you have drive failure.
