Veeam B&R 7 a list of issues and solutions

Now  I’ve been working with Veeam for a while now, and I’ve seen thatt mostly the case that when a backup job fails (or a surebackup job fails) or something fails, its most often not Veeam’s fault.

Veeam is a powerful product but it is dependant on alot of external features to function properly in order to do its job right. For instance in order to backup from a Vmware host, you need a vmware license in place in order to allow Veeam to access the Vmware VADP API’s.
If not Veeam can’t backup your virtual machines running on Vmware.

Also in order to do incremental backups properly Veeam is also dependant on CBT working properly on the hypervisor. So the real purpose of this blog post is mostly for my own part, but having a list of problems/errors that I come across in Veeam and what the fix is for it.

Now in most cases, when running jobs the job indicator will give a good pinpoint what the problem is. If not look into the Veeam logs which are located under C:\Programdata\Veeam\Logs (Programdata is a hidden folder) there is also possible to generate support logs directly from the Veeam console –> http://www.veeam.com/kb1832

Issue nr 1# Cannot use CBT when running backup jobs
Cannot use CBT: Soap fault. A specified parameter was not correct. . deviceKeyDetail: ‘<InvalidArgumentFault xmlns=»urn:internalvim25″ xsi:type=»InvalidArgument»><invalidProperty>deviceKey</invalidProperty></InvalidArgumentFault>’, endpoint: »

If CBT is for some reason not available and it not being used, Veeam has its own filter which it uses in these cases. Veeam will then process the entire VM and then on its own compare the block of the VM and the backup and see which blocks have changed, and the copy only the changed blocks to the repository. This makes processing time alooooot longer. Now in order to fix this you need to reset CBT on the guest VM. This can be done by following the instructions here –> http://www.veeam.com/kb1113 and one for Hyper-V CBT http://www.veeam.com/kb1881

Issue nr 2# Sure backup jobs fail with error code 10061 when running applications tests. This is most likey when a firewall is configured on the guest VM which only allows specific VMs. I have also seen this when a guestVM is a restarting state. If you do not have a guestVM firewall active, doing a restart of the guestVM and then do a new backup should allow the surebackup job to run successfully.

Issue nr 3# WAN accelerator failes to install. This might happen if a previous Veeam install has failed on a server. When you try to install the WAN accelerator the setup just stops without no parent reason. Something makes the installpath of the WAN cache folder to the wrong drive. You need to go into the registry of the VM and change the default paths as seen here –> http://www.veeam.com/kb1828

Issue nr 4# Backup of GuestVMs running on a hyper-v server with Windows Server 2012 R2 update 1, this is a known issue from Microsoft which requires an update from Microsoft –> http://www.veeam.com/kb1863

Issue nr 5# Application-aware image processing skipped on Microsoft Hyper-V server, this is of course related to many possible features. In most cases it is integration services, a list of the different causes and solutions are listed here –> http://www.veeam.com/kb1855

Issue nr 6# Logs not getting truncated on Exchange/SQL guest VMs, this requires application aware image processing and define that the backup job should truncate logs –> http://www.veeam.com/kb1878

Issue nr 7# Backup of vCenter servers –> http://www.veeam.com/kb1051

Issue nr 8# Backup using Hyper-V and Dell Equallogic VSS –> http://www.veeam.com/kb1844

Issue nr 9# Incredible slow backup over the network and no load on the servers, make sure that all network switches are full-duplex.

Issue nr 10# Win32 error: the network path was not found. When doing application aware image processing veeam needs to access the VM using the admin share with the credentials that are defined in the backup job. (For Vmware if the VM does not have network access Vmware VIX is used) It is possible to change the priority of these protocols –> http://www.veeam.com/kb1230
