Backup and ISO on a RAIDZ

[.n3]

Hey,

I'm new to proxmox and I have a 80GB HDD for Proxmox, a 1TB SSD for VMs and a RAIDZ as storage for NexCloud and other stuff. In my first try I create a RAIDZ, but I can only store disk images and container. I found a solution where you create the RAIDZ but do not add it to the storage.



After that you use

zfs create tank/backups
zfs create tank/isos
zfs create tank/vm-drives

After that I can add the dataset as directory to proxmox and use my RAIDZ for Backups, Images and VMs.

Is this the correct solution? I read, that this is not recommend for production, but I use it for my homelab. As far as I know it is not recommend because of the backups. Is it right, or are there more disadvantages? I planed to make a local backup and move it then to a OpenMediaVault NAS.

One disk? How should that work with RAIDz, which needs at least 3 disks.

Is this the correct solution?

yes

Why don't you just create the backups on your NAS?

Sorry for the missunderstanding. I want the following setup:

• 2x 80GB SATA SSD as RADI1 for proxmox installation
• 1x 1TB M.2 SDD for vms and container
• 5x 4TB SATA HDD as RAIDZ1 for storage
  • data tank for NextCloud
  • data tank for Frigate (Videos from security cameras)
  • data tank for isos, backups and templates

If I understand it correct, I can add further directorys to the RAIDZ1 if needed.

The NAS ist not in my network and will be stored in my fathers home. I can use a direct backup, but I don't know if it is a good solution because of internet connection.

Generally, it does not matter which vdev redundancy (here RAIDz1) you have in order to do stuff in ZFS pool. You can create as many datasets as you like (and have the space for). I would however say that you should add another SSD for your VMs and containers, it looks like you have your SPOF there.
