Hi,
For learning purposes --> I am trying to install Proxmox Backup Server (PBS), and configure it to use a partition of the boot drive to store the backups.
I was able to install it, but it's not clear how to configure it to use the boot drive as the data store. The following screenshot contains the disk configuration as it was installed:

My intent was to use nvme0n1p3 as the data store for my backups, but I was unable to select it due to a "no unused disk" error.
My understanding is that I need to format that partition as an ext4, zfs, or zfs file system for it to store backups; however, the EFI and BIOS boot partitions are slightly over 1GB combined (implying that critical information is stored on partition 3), so I am concerned that formatting partition 1 would break the server.
What am I missing here that would allow me to use this drive to store backups?
Thanks!
