Yes on both counts. Snapshots do cost money, and /mnt/galaxyTools is the right place to install new lib and programs. -Dannon On Jan 9, 2012, at 10:16 AM, mailing list wrote:

Thanks. It seems to me that http://aws.amazon.com/ebs/ says snapshots do carry a small charge. I might be reading it wrong though.

Also if I'm installing new libraries and programs, would those go in /mnt/galaxyTools?

Thanks again,

Greg

Greg-

When you make changes to the EBS volumes of a galaxy cloudman instance and choose 'persist' from the admin panel, an EBS snapshot is taken. The next time you start an instance up, instead of creating the EBS volume from the base snapshot that we distribute, it is created from your own customized snapshot.

The share string is actually a handle to a cloudman s3 bucket. That bucket contains all of the configuration information for your cluster and customizations. You can look at your own buckets to see the information saved, if you'd like. When the share-an-instance configuration steps happen and snapshots are taken, privileges are set to allow others to access those snapshots.

Since the customizations you make to galaxy are stored as an EBS snapshot, this does carry an extra cost. See more information about EBS snapshots at http://aws.amazon.com/ebs/.

And, lastly, if you're *really* interested in the nuts and bolts of how it happens, see the source here: https://bitbucket.org/galaxy/cloudman/src/tip/cm/util/master.py#cl-859

I was wondering how the sharestring feature works?

Enis mention it a little bit here: http://biostar.stackexchange.com/questions/15467/galaxy-cloudman-best-way-to...

So as I understand it, I do my customizations and persist them, and then I get a sharestring so others can load my customizations.

How does this work behind the scenes?

Also where are my customizations stored? Am I charged by Amazon for storing them? How do others have permissions to pull them from my Amazon account?

(I'm new to all of this, sorry if my questions are obvious)
