Planning to use a NFS share as PBS Datastore

Many PBS tutorials show how to use a local disk as a backup storage. I prefer not to use a local storage for keeping my backups since I have a reliable Synology NAS for my backup operations.

In the event of a rebuilding all VMs (including its PBS server) from bare metal, I plan to use a new fresh instance of a PBS to restore all VMs from all the backup files stored in my NFS storages.



Is it supported to use a NFS share as PBS backup server?



I tried this tutorial, but it seems to have important Synology permission settings missing. It is not accurate or not tested with PBS 3 +:

Is there any proven tutorial for integrating PBS with a Synology NAS ?
 
How many TBs of data do you plan to store? Local SSD-only storage is recommended because of the IOPS requirements. HDD-only storage over NFS will be so slow that I wouldn't want to use it for more than maybe 1-2 TB of backups.

The "backup" user (I think UID 43) needs access to that share. And you need atime or relatime enabled.

When it reaches to many TBs, I will scale to a dedicated hardware. At this point I like to evaluate PBS for 6 month on VMs smaller than TB.

I am new to PBS and I am battling with so many challenges - posted here.

Do you create the “backup” user on the PBS and on the Synology NAS.

I am not sure about atime and relatime. Is that configured on the NAS (the NFS server)? I need to look that up.

I tried creating a mount point /mnt/synology-nfs owned by “backupuser” and “backup” group with UID/GID of 1000 on the PBS. Then I created a user named “backupuser” with UID 1000 on the NAS. This “backupuser” has read/write access and owns the NFS directory /volume1/proxmox-backup on the NAS, which is what I use to mount to /mnt/synology-nfs. I was able to create the datastore on the PBS but I am getting errors about the chunks when trying to do a backup.
