Rebootable Backup

[NataliaMedrano]

Hello guys,

I am wondering if there is a solution to make a rebootable backup of proxmox set up.
The idea is having 2 disks - one disk with the proxmox set up, VMs and CTs. And the other disk to be a complete reboot backup. SO, if the first disk fails, the second disk can be used without doing any extra set up - like all the configs, VMs, OS, everything, would be in this second disk.

Is this possible to do? If so, how?

Ps: I am a beginner in Proxmox - so I am still learning everything I can do.

Thank you for your patience and help,
Naty

A zfs mirror should cover this, you can install the system that way during the initial install

I will have a look into it.

Thank you so much for your reply.

Another thing to consider: A zfs mirror is NOT a replacement for a proper backup due to the 3-2-1 rule (have at least three copies, two on different media and one in another location (family members place, cloud, whatever). Right now (even with zfs mirror) you have just one (your production). The mirror os not about backup but that you can continue running your system in case of the fail of one disc.
