I run a virtual NAS using BTRFS at home, because of snapshot capabilities and  SAMBA integration.
Today I red something very nice about a VEEAM update : they now supports the BTR filesystem !

I really love VEEAM because of the effective backup system ; and they provide lot of free stuff for typical homelab usage.

So let's take a look at the installation process !

Install the linux-headers

First, you'll need the linux-headers, so, just check your kernel version :

uname -r
4.9.0-8-amd64

And install the right linux-headers

apt-get install linux-headers-4.9.0-8-amd64

If you ask, this is why you'll need the linux-headers : https://blog.lbdg.me/veeam-agent-linux-failed-snapshot/

VEEAM installation

Surf on : https://www.veeam.com/en/linux-backup-free.html

You'll need a VEEAM account, which is free to create.
Once logged in, select the distribution you're using, and download the deb file

Install the deb package previously downloaded

wget "https://download2.veeam.com/veeam-release-deb_1.0.5_amd64.deb"
dpkg -i veeam-release-deb_1.0.5_amd64.deb

Like all "modern" application / service, this will just add a new depot in /etc/apt/source.list.d

New depot = apt update

apt-get update
apt-get install veeam

veeam is now installed

VEEAM configuration

To run the veeam configuration, just type

veeam

This will launch the agreements / licence wizard

Create, or not a MEDIA recover ISO (the ISO file can be downloaded from the VEEAM website)

Don't select any file if you're planning to use the free version

Ok, we've accepted all the agreements / licence, now, configuration time :

Press c to create a new job
And give a name to your new job

if you're using BTRFS, you need to select volume level backup and not the file level backup

Now add a BTRFS volume

Bellow, my BTRFS data set. I want to save what's inside the MEDIA subvolume, including the Test-VEEAM subvolume

So, I chose the /MEDIA AND /MEDIA/Test-VEEAM, because VEEAM will not recursively backup a subvolume level set

And after that, a classic VEEAM configuration
I chose a local destination for testing purpose

Encryption is really recommended and didn't cost that much CPU horsepower

And VEEAM will backup automatically everyday at 6 am your precious /MEDIA & /MEDIA/Test-VEEAM
