Having mixed servers with Proxmox and VMWare, I can say that VMWare + Veeam Backup&Replication is the best backup solution that I can think of. Incremental backups of VMs from which I can recover the full VM, only some virtual disks or even only some files from the guest OS. I can replicate backup to secondary storage, with periodic full backups (weekly, monthly, yearly). Deduplication friendly backups. Single console with great management and full backup reports.
Proxmox with vzdump is nowhere near to a solution like that, I'm aware. Obviously there are different costs.
In my Proxmox servers I decided to go for a double backup solution. I use vzdump for nightly (or weekly for big VMs) full backup. I use Veeam Agent inside the guest OS to backup the content of the VM (it can create differential backup) so I can recover single files at guest OS level.
