Good Morning Dannon this may not be a cost effective way of sharing data, cloud amazon charges $0.120 per GB data transfer, is there a work around ? also does that mean a worker node cannot communicate with master instance directly and use same below protocol to share history ?

To copy an entire history from one instance to another you will want to use the history export/import functionality. History context menu -> Export to file on the source instance, and Import from file on the destination. -Dannon On Tue, Nov 19, 2013 at 11:20 AM, Manisha Sapre <msapre@nmdp.org<mailto:msapre@nmdp.org>> wrote: Hello Team Galaxy trying to share/ forward dataset history from user 1 ( running on a local instance,Scrn.1) to user 2 (running on cloud amazon ec2 instance,Scrn.2) and vice-versa, error:- user is not a valid galaxy user. getting this error while both the users are logged into system and both the instance's are running normal. insights of team will be very helpful.
