Hi,
I recently set up a proxmox on an old PC. My proxmox and VMs are all on a 1 TB NVME right now.
I want to add a 256 GB SATA SSD as the proxmox system drive to system and use the 1 TB NVME exclusively for the VMs.
I was wondering how to achieve that. i.e. how to back up these VMs in a way so that they can be restored back after I install proxmox in another drive (SATA SSD). I read somewhere that these VMs can be backed up to a USB drive but I am not sure how.
Also, once I have proxmox installed on the SSD, which option to use for formatting the NVME drive for using it for the VMs.
Basically, I am looking for some guides/blogs/videos on how to do this migration and then once I setup my NVME which formatting should I use for that xfs, ext4, zfs?
Thanks!

The built-in backup function (VZDump): https://pve.proxmox.com/pve-docs/chapter-vzdump.html
Add some empty disk as a directory storage (PVE will wipe it!) or a NFS/SMB share, set "VZDump backups" as a content type for that storage and then that storage should have "backup" tab that allows you to backup/restore VMs.

Old PC sounds like you don't got proper hardware for ZFS (Enterprise/Datacenter grade SSD with PLP + ECC RAM). In that case I would use xfs/ext4 + LVM-Thin for better performance and less SSD wear.

Thanks, I will check it out.
I am not aware of the hardware requirements for ZFS, but the PC that I have is a HP desktop with 6th gen i7 processor and 48GB DDR4 RAM. The mobo has one NVME slot and 5 SATA ports.
