Get the documentation. It describes several different methods of backing up a
VM. Shutting down the VM, pausing the VM and using a
functioin "ADDREDO" which leaves the VM running and changed blocks are
written/saved to the redo file. At the end of the backup you
issue a COMMIT of the redo log into the VM. Here's some links.

Then there's this Tivoli Field Guide - Using IBM Tivoli Storage Manager for
Backup and Restore on the VMware ESX Console

Uhm, our esx work in real production environment, so we cant suspend machine.
And, to be more critical, we haven't dedicated backup window ...
