No, the patch isn't "meant" for anything. It's something a user provided. It may or may not apply for your version since it's a diff file. Again, if you don't know what this is you've got serious reading to do before looking to apply a patch. It's your own risk (or reward) when applying a patch and in short "if you don't know how to do it you shouldn't try". Being that this is for work you should *definitely* stick to running releases only or paying someone with far more knowledge to make it work. For work-related stuff you are always better off doing your own stuff in a jail than a plugin. Plugins may or may not ever have an update and you may or may not be able to update them later (read up on the 20+ threads on "Plex plugin won't update.. help!" stuff). So be warned you may find yourself in trouble later if Bacula suddenly requires some particular version or newer and you don't meet that requirement. Believe me, many people have had this problem with other plugins. Plugins are nice because they are push-button installs. But they have major limitations that can bite you in the booty later. This is particularly nasty if you are in a work environment because if you use a plugin you probably couldn't create the jail yourself, so when something goes wrong your boss is going to expect you to fix it and you may not know how except to delete the whole plugin and start over.
Yes, the only way to learn is to ask questions. But your question is outside the scope of this forum so I'm trying to push you in the right direction without leaving the thread unanswered. Not that you can't ask, but you probably won't get the answer you want. ;)
What phoenix said about patches is true, but that applies to the OS. Not to the jails or plugins themselves.
