Proxmox Configuration Help

[rbeard.js]

Hi there,
Im trying to set up proxmox in probably a non standard configuration and I was wondering if someone could help with some input.
We have 5 nodes in a cluster. Most of the nodes are set up with HA just as a failover. They use replication each night and they will spin up that mornings replication if something goes wrong. They all have their own storage setup on each device.
2 of those nodes I would like to have high availably on for one or two critical vms. Can I do this with some kind of external shared storage for just those two vms? I was wondering what I might be able to use as an external storage solution that would be fast enough for the vms on the server. I was thinking an unraid server and trying to avoid ceph as I cant install any more storage on the servers that is already in use on the other nodes.
Would unraid backing the vms work well enough here?

A couple of other questions.
I have backups and replications set up for all my vms but I was wondering what I could do to backup the nodes themselves?
Speaking of backups, is there anyway to use a nested folder on a SMB share for backups? Proxmox seems to only allow me to select the root of the folder which makes things a little unorganized.
Finally if anyone has experience passing through GPUs, I still have a pending thread trying to solve that issue.

Thank you for your time and help everyone!

No, but you should keep a recent backup of your nodes configs. Atleast the "/etc/pve" folders were most (but not all) configs are stored.

No. But if you want to save some downtime, bandwidth and disk storage you should have a look at Proxmox Backup Server (PBS). Its way more efficient because of stuff like deduplication.

I was looking at that but I didnt want to have to setup a whole other server. Can I run it in my unraid as a vm and share stoarge?

我正在看那个，但我不想设置一个完整的其他服务器。我可以在我的 unraid 中作为 vm 运行它并共享存储空间吗？

you can use vmware create new vm for nfs backup server then use it. my english not good

Depends on your performance needs and size of your backups. Here I'm running PBS as a VM on my TrueNAS server and that works fine so far...even though it is using HDDs as storage over NFS protocol. But keep in mind that PBS needs IOPS performance, so HDDs should be avoided or atleast SSDs should cache the metadata. Official recommendation is to run it bare metal with only enterprise SSDs as a local storage.
