Hello

I have a question regarding the backup. I have seen in the docs that there r 3 types of states while making a backup:

Stop/suspend/snapshot

Stop - will take too much to kill and exchange server till the image is dumped

Suspend - it actually shutdowns the image at some point ? - i see alot the startup menu on the windows servers asking me for a reason why i shutdown the server when i am trying to login

Snapshot - does it work online without a shutdown?

Which 1 is the safest? And trusted the most?
