Invalid arguments: Virtual machine has no snapshots
I ran into an very interesting issue today with a client who is using Veeam Backup and Replication to keep their virtual machines replicated to a remote ESX server for disaster recovery. Veeam starts a replication job and will take a snapshot of the virtual machine and then replicate the main VMDK disk file to the remote site. When the backup job finishes Veeam will tell VMware to remove the snapshot until the next replication schedule runs. Since we are replicating our VM’s across a slow WAN connection (600Kbps optimized with Citrix WANScalers) the replication can often timeout, or hang. Today I noticed that the replication had not updated since last night. So I needed to stop the replication and re-start it. Since the Citrix WANScalers can cache as well as compress, restarting a failed replication job is usually pretty quick, as most of the data was previously cached on the Citrix boxes.
Here are the details of what I found, and how I fixed it…
