I've had a Mercury 1.1beta setup at Amazon using an AMI for a few months now. Since this box has been a development box, I hadn't bother to setup automatic snapshots. I was doing them manually from time to time.
Now that we are getting closer to something that will become production, I would like to enable automatic snapshots.
At the time I setup my first instance, which happens to be Instance Store - I followed the document "Set up EBS for Mercury" which describes how to attach an EBS volume and copy www-data and MySQL data to the attached EBS volume.
Note steps 6 and 7 are incomplete which seem to be the bits of information that I need.
I also found "Consistent EBS Snapshots for RAID arrays or single volume with Mercury"
I also found "Mercury EBS Boot Instance" which tries to tie in all of the documentation regarding EBS volumes and backups/snapshots.
However, it says "Not sure if this is needed since an EBS Boot Instance is already on EBS" when referring to "Set up EBS for Mercury" and "Move Pressflow to the EBS Volume" pages.
This page is also mentioned several times on g.d.o
There seems to be a lot of information spread in several locations, and I'm not sure which is the best way to go with this. If someone could put the commands together, I would gladly update Steps 6 and 7 in the Set up EBS for Mercury" wiki.
