Virtual appliance in ESXi environment (Agent for VMWare)
You perform an agentless backup of a VMWare virtual machine using an ESXi appliance.
After you run the backup task, virtual machines show unexpected behavior, e.g. VM temporarily freezes or permanently freezes after logging into the VM.
If the freeze or other unexpected behavior happens after a successful backup of a VM, the issue may be caused by the specifics of virtual machine configuration.
If adjusting configuration to avoid errors during agentless backup is not possible, as a workaround, you can install Agent for Windows / Agent for Linux inside the virtual machine and perform agent-based backup.
