I am off soon to my first Zerto installation (nothing special, just a couple of SQL Servers), so probably this can be a silly question. I am trying to gather as much info as I can, but one thing is not clear for me about if it is necessary to protect the ZVM or not.
Let’s say that the ZVM is installed on a Windows VM. What happens if the VM or Windows crashes? Should I include the VM into the protected machines or just a new installation and use the PRESEED function?
Certainly every setup is different, and everyone has different tools to work with. I’ll outline what I do, and see if it helps you.
I do NOT replicate my ZVM machine via Zerto to my DR location. The reason is, it doesn’t do me any good, if I recover it at my DR location. It has to be at the production location to serve any function.
That said, your point about a VM crash is well founded. To protect the VM from a blue-screen, crash, hardware fault, or really any sort of outage that necessitates the need for me to restore the ZVM machine to a prior point in time (or in its entirety) I use my backup product, in my case, Veeam. I back it up locally (for the quickest restores) and a 2nd copy goes to an offsite repository (so I’m covered in the event of a catastrophic failure).
What this does is lets me have a way to easily restore the ZVM virtual machine, back into my production environment. Let’s say that a Windows update blue-screens the VM and I forgot to take a snapshot first. I simply rollback the VM from backup.
Now, keep in mind, this is only what I do. There are many different way to protect a VM. Perhaps you could even leverage the off-site backup functionality of Zerto. One of their guys could explain that better than I could.
thank you for your comments, this can be really helpful. It’s always good to know how other colleagues manage their environments in order to build your own ‘best practices’.
