-3948 VCB API Exception - vSphere DR

i had a issue where my vSphere Data Recovery backups would not start, each time they displayed the error -3948 VCB API Exception. Not exactly a clear error message to go at.

I then noted that I had made changes to my internal DNS and the internal DNS server the appliance was using we no longer in service and this error is really a DNS server to say I cannot find any host names for the ESXi Servers.

I changed the DNS in the appliance via the console and then the update allowed the backups to start correctly.

This will give you a good overview report including the files using the most disk I/O and memory.

It is a good place to start when performance troubleshooting.
