    comment Most Appropriate log-structured file system to use with Linux / SSD?
    Yes, modern SSDs targeted for server/desktop use spread writes quite fine. Just make sure that you reduce the amount of "unncessary" writes, if you're concerned about device wear. Disabling atime updates, as suggested above, is a good first start if you don't run applications which depend on it's presence.

    comment Naming Conventions
    Since we used either OpenVZ or VMware ESX on all of our physical servers, those had according names. The few machines without hypervisor we had, had very specific hardware catered for a single task. E.g. the backup machine had room for 16 3.5" disks and would be reinstalled if it were to be repurposed, and this would've included assigning a new hostname. And the virtual servers all had very specific hostnames and often served only a single service/task (which was reflected by the hostname).

    comment What's the most efficient way of taking backup snapshots of a mysql database over the internet?
    The more I think of it the more I'm convinced that your best bet is plain rsync with --compress. Both gzip and rsync can produce completely different output when the input is shifted (far enough into their respective blocksize).<br>I don't know how the pattern search algorithms in rsync exactly work, if you find anything on this, please do tell ;).
