> 1. Is it possible to backup database using rsync?
In Windows I perform a series of NET STOP <service> commands prior to
issuing a Rsync command.
This stops the database and allows me to back up its files.
Then afterwards I simply reverse the stop commands with NET START
Works for me.
You can do a similar thing in any OS you may be using.

Rsync can't copy open files. So you need to temporary stop the service
that keeps the file open. Not difficult.

What do you mean by 'handle'? And why would it be special?
If you can't stop the services then you'll need to find a Copy program
that does 'shadow copy' of open files. Assuming you're running Windows.
I don't know what term Unix, Linux or Macs use.
But you're talking about having to spend money.
Look up 'Shadow copy' on Google.
