==Introduction== <!--T:1-->

Nous allons voir dans cet article comment corriger le warning "Failed to perform backup. Neither [blksnap] nor [veeamsnap] module was found." sur la VSPC. 

[[Fichier:01_veeamsnap_error_not_found.png]]

==Cause==

L'installation du module Veeam permettant de faire un snapshot des volumes ne s'est pas installé correctement.

Ces modules s'appellent '''veeamsnap''' ou '''blksnap''' selon l'OS. 

Dans la plupart des cas, la cause est la non présence des headers Kernel nécessaires à l'installation du module. 

==Correction==

Il suffit d'installer les headers Kernel dans un premier temps: 

<pre>
apt-get update
apt-get install linux-headers-$(uname -r)-amd64
</pre>

<div style="background-color: #FFCC99;"> '''Note''': Si les headers kernel n'existent plus dans les repos pour la version du kernel sur lequel votre OS est démarré, il faut redémarrer votre serveur la dernière version du kernel disponible dans les repos.</div>

Reconfigurez ensuite '''veeamsnap''' ou '''blksnap''':

<pre>
$ dpkg-reconfigure veeamsnap

-------- Uninstall Beginning --------
Module:  veeamsnap
Version: 6.0.3.1221
Kernel:  3.16.0-9-amd64 (x86_64)
-------------------------------------

Status: Before uninstall, this module version was ACTIVE on this kernel.

veeamsnap.ko:
 - Uninstallation
   - Deleting from: /lib/modules/3.16.0-9-amd64/updates/dkms/
 - Original module
   - No original module was found for this module on this kernel.
   - Use the dkms install command to reinstall any previous module version.

depmod....

DKMS: uninstall completed.

------------------------------
Deleting module version: 6.0.3.1221
completely from the DKMS tree.
------------------------------
Done.
Loading new veeamsnap-6.0.3.1221 DKMS files...
Building only for 3.16.0-9-amd64
Building initial module for 3.16.0-9-amd64
Done.

veeamsnap:
Running module version sanity check.
 - Original module
   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/3.16.0-9-amd64/updates/dkms/

depmod....

</pre>


Redémarrez ensuite le service veeam:

<pre>
$ systemctl restart veeamservice
</pre>
