</div>


<div>
if you can mount the partition it is formatted.<br />
&nbsp;mount<br />
if it is listed it is formated.<br />
<br />
<br />
As an advice, you are missing swap in your partitioning.<br />
<br />
Consider using LVM as the overlay<br />
<br />
provides for dynamic partitioning.
</div>


<div>
Is the flavor of filesystem on /dev/sda3 something that Veeam understands? &nbsp;(is it ext4, zfs, btrfs, etc etc)
</div>


<div>
Check your veeam settings and whether it reflects how.mich of the actual data in use it backed up.<br />
I.e.our of the 1.7T available space, currently only 15.6FB are ised.<br />
Veeam does not backup the empty space to reflect the entire partition's size.
</div>


<div>
are you sure you did not format 15 GB ? &nbsp;it's only a matter of comma

try mount /dev/sda3 /mnt<br />
and see if it can be mounted.<br />
<br />
Was this just an initial install? 1.8TB 99% of your capacity is part of this /dev/sda3 partition.<br />
<br />
It might be easier if you specify what it is you are trying to do, and whether it should be reinstalled with better partitioning

arnold - This was an initial install. &nbsp;Total hdd space is 1.8TB on bare metal. &nbsp;We are using Veeam as our backup/replication tool. &nbsp;We are attempting to setup Immutable backups through Veeam. &nbsp;We have 0% experience in Linux and are trying to work through this. &nbsp;I have taken two online course on Linux. &nbsp;So very limited (dangerous) knowledge about Linux or it's infrastructure. &nbsp;But you have to start somewhere. &nbsp;So I have an initial install of ubuntu 20.4.2. &nbsp;I have successfully installed VNC to provide remote control capability while in the lab. &nbsp;I have presented the Host (Linux) to Veeam. &nbsp;I am attempting to set up a Veeam backup repository using excess capacity on the Linux server. &nbsp;That capacity seems to be associated with sda3 (1.7TB). &nbsp;Once I have access to this storage space, I would create a backup job in Veeam pointing to this storage and set the backup to be immutable.<br><br>mount: /mnt: /dev/sda3 already mounted or mount point busy

Have installed 1.8TB of space on Ubuntu 20.4.2 server.  I show 1 logical drive sda with three partitions; sda1, sda2 and sda3.  I would like to store immutable backups on sda3, however, when I point our backup software (Veeam) to the server partition /dev/sda3/ it populates a value of 15.6GB.  I don't understand where it is getting this and thought maybe the partition isn't formatted and returning bad data.

New to Linux - how to tell if a partition is formated?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things.

Ubuntu

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.

Linux OS Dev

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
