In the previous posts of this short series, we announced the availability of Veeam Agent for Linux Beta and gave everyone a few quick tips on how to start using it. We showed how easy it is to work with the graphical user interface (GUI) in order to back up and restore files and volumes, but no program would be a true Linux solution without complete support for the command line.

Today, we’ll see how to operate Veeam Agent for Linux from the shell!

Introduction

Once the software is installed, a service is installed and configured in the Linux machine. On a Systemd Linux distribution (e.g., CentOS 7), you can check the service and its status with the command:

systemctl status veeamservice

Veeam Agent for Linux Beta

You can see that the service is active and running. Any command we run via the shell is not executed by the command itself, but instead is passed to the service that will execute the command. This means, for example, that a backup can be completed even if the user logs out after running the backup as the commands are passed to this service.

Backup

In order to create our backups, we must create at least one repository.

But what if we do not remember the exact command? veeamconfig is the command line tool, and it has an online menu that can be invoked by using veeamconfig help (or --help or -h), or we can also run the command without options and see the available sub commands:

Another way to quickly select any sub-command is to hit tab after the main command; if you have bash completion installed in your system, you will immediately see the available sub-commands:

In our case, we see there is a repository sub command, and if we now run veeamconfig repository without additional options, we can learn how to use this option.

Thanks to this functionality, we quickly learned all the available options and we are now ready to create our repository using:

veeamconfig repository create --name STORE --location /mnt/store/

The command returns the result “Repository was created successfully.”, and we can see it now listed among the available repositories:

Note that to create a remote repository like an NFS share, you need to do it from the graphical interface. You can only create a local repository via the command line.

Now we can create a backup job. The command is going to look like this:

veeamconfig job create --name Backup_root --repoName Repository_1 --maxPoints 7 --objects root

We instructed Veeam Agent for Linux to create a new backup job, whose name is “Backup_root”, the repository to be used is “Repository_!” (the remote NFS share), that we want to keep seven restore points and the content of the backup will be “root”. Root is the name of the LVM logical volume /dev/centos/root, mounted as / in the file system.

Veeam Agent for Linux returns the result “Job was created successfully.”, and we are now ready to run it. To do so, the next command we need is:

veeamconfig job start --name Backup_root

Veeam Agent for Linux returns the status of the operation:

Backup job is started.

Session ID: [{64bbf9db-c83c-4ca4-b60a-e93301db8de3}].

Logs stored in: [/var/log/veeam/Backup/Backup_root/Session_{64bbf9db-c83c-4ca4-b60a-e93301db8de3}].

The job is now running in unattended mode, but we can check its progress:

Veeam Agent for Linux Beta

We can see the last session is in state “Running”, and our backup is progressing. We can eventually run veeamconfig session ui to see the progress using the GUI, but this blog is all about the shell, so we are only refreshing the session list until this last backup is listed as Success. For example, we can run:

watch veeamconfig session info --id 64bbf9db-c83c-4ca4-b60a-e93301db8de3

Veeam Agent for Linux Beta
The backup is completed successfully.

Restore

A file restore can be invoked by the command line too by using a few simple commands.

First, let’s recap the backups we have available:

veeamconfig backup list

Job name     Backup UUID                             Repository    Created at

BackupJob1   {1dde4e0d-b90e-4a7a-9e3e-65a182ada70f}  Repository_1  2016-06-14 21:00

Backup_root  {eaf8c7fa-3048-4b41-a917-9418f876662b}  Repository_1  2016-06-14 22:51

We can immediately mount the backup using:

veeamconfig backup mount --id eaf8c7fa-3048-4b41-a917-9418f876662b --mountdir /mnt/backup/

The result of the operation is returned from the software:

Backup is mounted.

Session ID: [{3aaadffb-2299-4d7f-a60c-4af4fac4afee}].

Logs stored in: [/var/log/veeam/Mount/Session_{3aaadffb-2299-4d7f-a60c-4af4fac4afee}].

Note that, compared to the simplified operations offered by the GUI, we can configure the mount point for the backup restore here.

Additional options

The command line has a complete set of features, not just for managing backups and restores.

For example, from the command line is possible to manage configurations. By running the command:

veeamconfig config export --file config.txt

We obtain this result:

Configuration file has been exported successfully.

The configuration of Veeam Agent for Linux has been exported in a text file, ready to be edited. The software uses a local database to store not only configurations, but also session history, backup jobs, repository and practically any information that is visible in the software itself. While the only method to interact with the database and its stored configurations is the Veeam command line, users may need to edit these information using different tools, like automation solutions. That’s why the config command is available.

The export command stores the configuration in a text file using XML format:

<?xml version="1.0" encoding="UTF-8"?>

<Config Version="1" />

<Repositories>

<Repository Name="Repository_1" Type="Share" RepositoryOptions='&lt;OnShareRepositoryOptions Version=&quot;1&quot; Address=&quot;10.2.50.56:/var/nfsshare&quot; FsType=&quot;nfs&quot; Login=&quot;&quot; Password=&quot;&quot; Domain=&quot;&quot; /&gt;' />

<Repository Name="STORE" Type="LocalDrive" RepositoryOptions='&lt;LocalRepoOptions Version=&quot;1&quot; Location=&quot;/mnt/store&quot; DeviceMountPoint=&quot;/&quot; /&gt;' />

</Repositories>

<Jobs>

<Job Name="BackupJob1" creation_time="2016-06-14 19:00:33" RepoName="Repository_1">

<JobOptions Compression="Lz4" BlockSize="KbBlockSize1024" PrefreezeCommand="" PostthawCommand="" MaxPoints="14" IsDedupEnabled="false" Schedule="false">

<Schedule Hours="0" Minutes="0">

<WeekMask Sunday="false" Monday="false" Tuesday="false" Wednesday="false" Thursday="false" Friday="false" Saturday="false" />

</Schedule>

</JobOptions>

<ObjectsForBackup>

<Object ObjectType="AllSystem" RecordType="Include" Value="" />

</ObjectsForBackup>

</Job>

<Job Name="Backup_root" creation_time="2016-06-14 20:50:51" RepoName="Repository_1">

<JobOptions Compression="Lz4" BlockSize="KbBlockSize1024" PrefreezeCommand="" PostthawCommand="" MaxPoints="7" IsDedupEnabled="false" Schedule="false">

<Schedule Hours="0" Minutes="0">

<WeekMask Sunday="false" Monday="false" Tuesday="false" Wednesday="false" Thursday="false" Friday="false" Saturday="false" />

</Schedule>

</JobOptions>

<ObjectsForBackup>

<Object ObjectType="SimpleDisk" RecordType="Include" Value="/" />

</ObjectsForBackup>

</Job>

</Jobs>

<VbrServers />

Admins can use their preferred text manipulation tool and modify any parameter in the XML file. The Veeam service only relies on its local database for any configuration, so in order to let Veeam Agent for Linux load the new configuration after the changes, we have to import the edited config file:

veeamconfig config import --file config.txt

Immediately, Veeam Agent for Linux will use the new settings.

    Hi,

    Some questions –

    1) If I want to restore by booting with Veeam ISO, can advanced networking be configured? For example our blades have bonded interfaces on a VLAN trunk with LACP enabled, and this would need to be configured prior to restore.

    2) Can I backup by booting from the ISO? This may help for restores when applications need quiescing prior to backup, and shutting down the server is the safest way to do this.

      Hi,
      1) there is no such functionality in the network manager right now. It may be an addition in the future, bases on the amount of requests. You can post the request on our forums (https://forums.veeam.com/veeam-agent-for-linux-f41/) so that other people may add their vote.
      2) Not at the moment, as veeam agent is not installed in the recovery media. Shutting down the server may be the safest way, but the uptime of the services would be not ideal. You can leverage pre and post backup scripts in the agent to quiesce the application even without stopping the entire server.

    Hi, on a 32 bit Ubuntu 14.04 I can’t seem to stop a running backup? The page just freezes and I can’t get to the previous screen. Only ctrl+c quits the veeam agent but it keeps running its job in the background..
