Instructions:
Log in as root@pam in Proxmox.

Download Debian 10 (Buster) template

Install a minimal Container (2 GB RAM, 8 GB HD) and then choose the container/Options/Features and then enable NFS.

Do:
#apt-get update
#apt-get dist-upgrade

Install the repo key
#wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg

Add PBS debian package repo to /etc/apt/sources.list
deb http://ftp.debian.org/debian buster main contrib
deb http://ftp.debian.org/debian buster-updates main contrib

# THIS IS THE NEW ADDITION
# PBS pbs-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pbs buster pbs-no-subscription

# security updates
deb http://security.debian.org/debian-security buster/updates main contrib


Install the PBS-server software
apt-get update

apt-get install proxmox-backup-server


After a reboot all is installed and started, don't forget to set the IP-address you want to use
and mounting the NFS-share you want to use as the storage for backups.
Put the NFS-share into /etc/fstab to automatically mount it at reboot.

If I'd run Docker, yes, but as I run Proxmox standard on most of my systems this is a very easy and fast way of getting a workable
backup-system.

Yeah I was thinking it could be useful on synology NAS since they don't support LXC .... At least not that I know

Absolutely, BUT, you can run the PBS LXC on you PVE-host/cluster and use the NFS mounted storage. So no need to run on the Synology as docker.

NFS performance is really poor for PBS, better use iSCSI (attached directly to PVE host).

NFS isn't the fastest way but with a low-end NAS (Netgear) as the other side in this case, and PBS saturating the 1Gbit/s network it is enough.
Going with a separate server for PBS with local storage and a minimum of 10Gbit/s network for your Proxmox cluster is always the better choice.

But that wasn't what this excercise was about, this was settings up PBS for the SOHO-market without a lot of investments. Using PBS instead of VZdump with just storage gives you a lot better performance and better usage of the storage than not using it.

It also helps us heavy users in helping Proxmox as more use-cases usually means faster development and debugging. :)

Just my 2 cents...

why directly attached ? I was wondering how would be the performance vs a balanced 2x10G link on the nas using iscsi with a dedicated switch or vlan for it

Directly attached iSCSI drive to proxmox machine, I think it will not work in container. Don't use bonding for iSCSI, use multipath instead, bonding can be used with NFS.

yes i was thinking to use multipath. however with a dedicated switch or vlan it gives the flexibility to use the nas for other usages . I guess it depends on the usage . also it would be cool if PBS allows some caching or buffer usin a dedicated disk before writing to a a remote location.

I can understand local storage is faster but for a long term backup solution it doesn't make sense. using SAS or when you're constraint in tetm of budget or physical space iSCSI would give more flexibility. I hope it will be supported soon by PBS.

Followed your guide but get an "mount.nfs: Operation not permitted" Error when trying to mount the nfs share. Any ideas how to fix this?

Ahh, I forgot to mention that you need to enable NFS in the options of the container.

You have to log in as root@pam and then choose the container/Options/Features and then enable NFS.

Hi Azatot,

did you set no_root_sqaush on the NFS-server?

Best regards,
Rickard
 
Hi Azatot,

the only real setting you need on any NFS-server including FreeNAS/TrueNAS is:

root/wheel permissions on the dataset and no_root_sqaush in the NFS share settings.

Best regards,

Rickard
