When I browsed https://VCSA_IP:5480 -> Backup, & clicked on “Backup Now”, received the error “Invalid vCenter Server Status: All required services are not up! Stopped Services: ‘statsmonitor’“
192.168.0.156 is the IP Address of the FTP Server hosted on Windows Server 2012 R2, where the VCSA Backup would be stored.
Took SSH connection to VCSA & ran the command service-control --status --all to list the status of VCSA services & got below output
vmcam vmware-imagebuilder vmware-mbcs vmware-netdumper vmware-rbd-watchdog vmware-statsmonitor vmware-vcha vsan-dps

This error comes up when vmware-statsmonitor service is not running, however, for Backup to get started, below 3 services should be running (if not, in those instances, the error would show up the service name accordingly)
Ran below command to start the service
service-control --start vmware-statsmonitor
Once the service was started, browsed the same location within VAMI Page and was able to initiate Backup this time.
