this is is 5 year old (2019), i don't think that veeam consider proxmox.
With CE i can backup VM without problem, but the problem is that i can't see the second node in infrastructure.
i have the same problem like TaylorNP, i can added proxmox cluster with IP but i see in veeam infrastructure only one proxmox host.
i have a two node cluster, without qdevice.
remember that if you use proxmox 6 or more for multipath configuration you need to adjust multipath.conf
https://forum.proxmox.com/threads/multipath-iscsi-dev-mapper-device-is-not-created-proxmox-6.57272/#post-264048
in 6.x version of proxmox the multipath configuration is change.....
this is mine:
defaults {
find_multipaths no
polling_interval 2
path_selector "round-robin 0"
path_grouping_policy multibus
uid_attribute ID_SERIAL...
hi, i'm testing PBS, and i have same test Virtual Machine.
if the virtual machine is shutdown i see that the backup is full, if the virtual machine is start the backup use incremental mode (dirty-bitmap)....
Is this correct???
