To provide steps to resolve the snapshot failure
The failure is due to a larger VMX file size caused by guestInfo.appInfo information from the appInfo plugin. This is an application tool that is dumping alot of info into the VMX file. VCDR has a hard 55K limits on the VMX file size due to the way they are stored on the underlying filesystem.
VM protection will be impacted as VCDR cannot take snapshots.
Schedule a maintenance window for the VM and disable appinfo plugin via VMware tools configuration file at the VM level. To disable appInfo plugin, login to the guest with admin credentialsLinux Guest vmware-toolbox-cmd config set appInfo disabled true ORvmware-toolbox-cmd config set appinfo poll-interval 0Windows Guest VMwareToolboxCmd.exe config set appInfo disabled true ORVMwareToolboxCmd.exe config set appInfo poll-interval 0For additional information about appInfo plugin refer VMware tools documentation
