Case 00936246 - Failing replica jobs

[ms77ao]

Hi,

I have consistently been having problems with VEEAM Replica jobs failing. I have had several tickets logged with VEEAM Technical Support over this long-standing issue and the latest case number is 00936246 and below is a brief history of the problem.

The set up is quite simple

Client Site (Source Proxy) - running a instance of VEEAM Backup & Replication 7.0 which backups a number of virtual machines sitting on vSphere Infrastructure. The VEEAM Server is Windows Server 2012.

Datacentre site - running an instance of VEEAM Backup & Replication 7.0 and this is the target proxy which is only carrying out replica jobs for specific virtual machines that are being backed up from the source proxy.

I have 3 replica jobs running on the target proxy and would randomly find that they would fail and not one specific one so I started logging tickets with VEEAM who initially put it down to corrupt replicas and proceeded to delete all the replicas and consolidate the VM before re-running the job which temporarily resolved the issue twice until it happened again. One of the reasons for this problem was the target proxy randomly BSOD whilst a replica job was taking place and this was rectified as soon as it was bought to my attention. The replica jobs were working fine for another 3 weeks until a failure of the same nature again at which point this ticket has been escalated to a tier 2 engineer who has made some recommendations having reviewed some logs that were uploaded.

1. The target proxy server is being backed up by another VEEAM Server which has caused a VSS freeze and that led to a loss of connectivity between the source & target proxies. I am looking at potentially only taking a configuration only backup of the target proxy to avoid this problem in the future.

2. Change the transport mode from virtual appliance to network on the target proxy - recommended by VEEAM Support.

Looking forward to hearing from anyone who has experienced this problem.

Regards,

Sunil

Sunil, have you already followed these latest recommendations? They look totally reasonable and I would appreciate if you could share whether they finally worked for you.
