Server Snapshots for maintenance
I have been looking at Owncloud last week and almost got it up and running except that when I sync from client to server it kills the server and apparently this is due to the version we are using. I can't update it as it is the latest stable version so I want to try an earlier version instead. I've been using snapshots on a Windows 7 machine to help test new software installs and then reverting back to a nice clean state when finished. It occured to me that if I had taken a snapshot of the server before installing Owncloud I could have reverted back to before the installation rather than having to uninstall it.
I have read that it is not a good idea to snapshot live servers as it affects the replica's but as I would only use a snapshot to test upgrades etc, does anyone use them before making updates to servers? Or would you just fail back to the replica if you found that any upgrades/new software caused problems?
