When utilizing multiple users against the same Agent to run deployments, or other actions that utilize the 'backup' functionality, all users after the first user within a day will fail displaying a permissions denied error.
The creation of the filesystem for resources does not provide a 777 permission, so when:
Is created, the /Date is owned by the first user that creates a deployment and that does not properly pass permissions to all other users.
Release : 12.3
Component: Automation Engine
This will be fixed in a future release.
To workaround this behavior, after a date folder is created, modify the permissions to 777.
