In short, "yes".</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">There are two main elements to consider: the servers themselves and the data on the servers. Not sure how much of a standard this is, but it works for me:</div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">I have a script that snapshots my entire system volumes once a week. If config changes were happening at a rapid rate for some reason, I'd shorten the snapshot interval. The script deletes snapshots older than four weeks. I snapshot the entire machine rather than configs. In the event of total loss I just slap the entire system image into service. Kind of a sledgehammer I s'pose, but this way there's there's no risk of forgetting about that oddball script that for Some Good Reason never made it into /opt with the rest of them.</div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Another script snapshots data volumes. Those snapshots are typically stored for 30 days in my case.</div><div class="gmail_default" style="font-size:small">
<br></div><div class="gmail_default" style="font-size:small">For MySQL, I used to have a scripted snapshot arrangement on my own servers, but now I use Amazon's RDS service. If you're running MySQL, I believe you need a really, really good reason to roll your own vs using RDS. </div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default">I tried various hacks before finding this python script. It's simple and solid and all the work's been done: <a href="http://aws-musings.com/manage-ebs-snapshots-with-a-python-script/">http://aws-musings.com/manage-ebs-snapshots-with-a-python-script/</a> I love this script and never even knew that there was an AWS module for Python before.<br>
