Ix-applications permissions for rsync user

Hi!

I’m trying to set up an rsync task to back up a storage pool to an external NAS. The pool contains, among other things, the ix-applications folder. When I try to run the rsync task it eventually fails when it reaches the point to start sending some of the ix-applications contents because the rsync user I’ve set up does not have the permissions to read some directories there. Is there a way to do it?

Cheers,
Pau
