It sounds like the deferred job plugin will work as a mechanism to manage the jobs, once there is a tool that communicate to two different galaxy instances via the API and order them to start transferring/loading files. I think the tools '__EXPORT_HISTORY__' and '__IMPORT_HISTORY__' (under lib/galaxy/tools/imp_exp/), but with some options to select subsets of elements from a history, would be useful in the case. Then I just need to command them via the API.
But there still may be a problem with mapping IDs between the systems...

I'm trying to figure out if I can do this all through the API (so I can

I can scan one system, and initiate downloads on the destination system
(using upload1). So as far as moving files from one machine to another, it should be fine. I could push all the data, with correct names, annotations and tags.
But then it becomes a matter of the pushing the metadata onto the object
on the destination system. But there are two problems,
- No way to push tool info and input parameter data, everything would
be a product of 'upload1'.
- No global IDs. If I try to sync a second time, it may be difficult to
figure out which elements have been previously pushed. Comparing names could lead to problems...
Hi Kyle,
The transfer manager was designed as a very general method of downloading data to a temporary location in a Galaxy-independent-but-manageable fashion. To make it more useful, it's designed to be used with deferred jobs. The idea is that you write a deferred job plugin that can be told when to initiate a task (like adding things to the transfer manager), create deferred jobs that depend on those transfers, and then take certain actions that you specify once those transfers have completed. There's no documentation, but if you have a look at the existing plugins in lib/galaxy/jobs/deferred, that should give you an idea of how it works.

A good practise is to create a ftp server
http://wiki.galaxyproject.org/Admin/Config/Upload%20via%20FTP and use a tool to send / retrieve informations to this ftp server :
http://toolshed.g2.bx.psu.edu/ -> Data Source / data_nfs
Then export your ftp directory by NFS to your galaxy installations.
For databases, it is a little bit complex. If you have a database
server, you could share access to a single database, but your installation between your server should be the same, and all working directories must be shared with NFS on all galaxy servers...

2012/12/6 Kyle Ellrott kellrott@soe.ucsc.edu Is there any documentation on the transfer manager? Is this a mechanism that I could use to synchronize data libraries
between two different Galaxy installations?
