There is a SO question on this. you could search sync-everything-from-google-drive-business-to-another-business-account in SO.
The question is mainly about
Does the command line support sync folder from the business drive to another business drive in a different domain?
let say the source folder in account A is Folder A. The target folder in account B is Folder B.
Without rclone. I will do it in this way, I grant account A access to a folder in the shared drive created by account B. Let this folder be Folder C.
Each time period (maybe 1 day) I use python to capture tree structure in Account A. I use the tree to copy Folder A to Folder B. And then copy Folder B to Folder C.
lol, it must be --magic
but seriously, not 100% sure about using it across two different domains, but gdrive allows for that, so rclone makes use of it.
a simple test using a debug log would give the answer.
as for the script, it is over 600 lines, runs only on windows and orchestrates
rclone
7zip
fastcopy
Microsoft VSS - Volume Shadow Copy Service, snapshot technology for backing up in-use/open files
complied as a portable .exe file
i have been thinking about writing a post about it here in the forum, and if there is interest, posting it at github.
tho i am not a professional programmer, i have been using it for approx. two years on a bunch of desktops and servers.
if you have a specific question about using python with rclone, please ask....
