Exchange - how to download all backed files ?

Hi everyone,

I’m in need to download all the pst files from our exchange server.
Is there a way to connect azure to cloudberry exchange and have the backup on the server synchronized to azure ?

I was thinking to do an export from exchange(on site) to a one drive folder, but this would mean downloading/uploading at the same time and I’m afraid of corruption in the process as the size is 600-700GB.

Any solutions for this ?
