Hyper-V 2012 R2 setup
Veeam 220.127.116.111 installed on VM Server 2012 R2 Std
Cluster Hyper-V with CSV (dedicated iSCSI SAN)
Backup repository - Windows Server on LAN with lots of disk space
Create simple backup job, which never happens.
In the log I see:
VM host 'SP-SR1-VHOST02' is locked by creation of another snapshot by task 'e67c5401-e811-4237-be1e-b5b5d99f35f2' [12.01.2014 21:14:41] <10> Info [RTS] [Task '7a7470ab-a128-4332-b251-1d613d83be61'] Unable to allocate on-host proxy : One or more volumes is locked by creation of another snapshot (by task: e67c5401-e811-4237-be1e-b5b5d99f35f2)
Stopping the job takes over 5 hours

Can you confirm that there is no snapshot activity at that time of backup, as, according to the log, it is the root cause? Also, be aware that the team behind this community can help you with debug logs analyzing, so, you'd better contact our support team with this.
