Question on PBS setup and hardware

[marar]

I have ran PBS in the past on bare metal and had no issues, but my setup has since change and looking for some help on which direction I should go if not running bare metal anymore.

Would it be better to ...

1. Install PBS as VM on Proxmox and backup to a NFS share on Synolgoy.
2. Install PBS as VM on Synology.

1. Install PBS as VM on Proxmox and backup to a NFS share on Synolgoy.
2. Install PBS as VM on Synology.

Both (!) is suboptimal. (You know that, right?)

But if I am forced to choose: the PBS (or any backup system) should be independent from the source it will backup. You'll probably want the backup to be available and usable when (not: if!) the source dies, right?

I suggest that option 2 is preferable, except it won't protect you in the case of fire or flood in the home, but I'm sure that you are aware of that.

Technically both options the backup is still available if the host dies, though one is a little harder to recover. I know it's not optimal and is why i have ran bare metal up until now. Just looking at best option short term and know many people run it in a vm on pve.

Thank you, yeah fire and flood would not be good. I do have cold storage off site for more important things to try and help with that.

You can try to use the NFS as a removable storage in PBS, if the PBS host dies, you can create a new one, and add the storage again as a removable existent media.
If you use this trick you can access again to your backups.

Please test you selected proxmox bs setup and compare it with a single proxmox bs server with zfs on enterprise ssd.
You need read 10^5 - 10^7 4M Blocks every time the proxmox bs run.
You need IOPs every time.
And a ZFS Pool with 2x VDEV[0,1] zfs mirror of 2x HDDs and VDEV2 zfs special device of N x SSDs N >1 can/ will work too.
I give my proxmox bs with zfs, 32 gbyte ram and up to 24 gbyte ram arc cache.

I understand that those are best practices, but those specs are difficult or too costly for most who are building a homelab, remember that for most it's just a hobby or a learning tool, so the costs matter.
