Address Book and iCal Server backups

Question

I'm working to implement a company-wide Address Book, iCal, and iChat server via Lion Server where I work, and I've gotten most of the setup figured out (I think), and am approaching the point where I can roll it out to a few users for further testing.  However, before I'm allowed to move forward any further w/ it I have to have two means of backing up in place and ready to be rolled out at the same time as the server—so I'm planning on using Time Machine as one so it does the entirety of the server and its data/settings, but they also want me to do one of the Address Book Server and iCal Server databases individually, like back up the folder the data is, so we can, if ever necessary, import the backup databases to another computer, so we at least have the content, if not the full server functionality.  And, for obvious reasons, it can't be backed up locally. 
So I'm looking for a means of doing this and would love any input anyone has.  Ease of use/setup is pretty important as this is my first time setting Server up and I've no programming knowledge.  I'm fairly sure I'll be able to find (or write my own, though that's unlikely) or modify and AppleScript that simply copies/duplicates a Finder item, and I know I can have iCal automatically run a script (so I'd just have it run every night at midnight or something), but I have yet to figure out how to get the script to copy the folder to a specified location on a different server (or, for that matter, if it's even possible, though I'm sure it is...right?).  But that's not what I'm trying to ask here...though I certainly wouldn't mind if someone had thoughts on it and wanted to share them !  I just really would like to know which folders to back up, since it's not simply making an archive of the local Address Book.app database.
And, since I'm already here writing a post, I'll ask one other question that's been nagging at me: in Server Admin.app, with the server (not the services) selected in the sidebar on the left, the Access pane selected in the primary Server Admin window, and Services selected, and trying to dictate which users/groups can access which services, the user can click the "+" in the lower-left corner of the window where added users would appear, and another window pops up next to the Server Admin window that shows a list of the users (and groups if you click the appropriate button).  My question is, why does it show me _krb_anonymous, _krb_changepw, and a total of 81 other items?  I understand more or less what they are (in a very general sense), but why are they shown as users?  More importantly, do they have to be listed there?  Technically I'm probably the only one that's going to be the administrator, and I'll know not to add them or modify them, but I don't want anything related to those items appearing in a directory search in Address Book when I get it set up (as they are showing up now; for instance, one user I created is Sandy, and I have it set to include directory contacts in searches, so on a client machine that is correctly communicating w/ the server (add a user, it appears in a minute on another client machine, and vice versa) if I go to search for that name as soon as I type "s" Sandy, the actual user shows up, but so do five or six other things, all of which are items from the aforementioned list in Server Admin (pretty much anything that has an "s" in it, which of course makes sense)—and that's what I don't want, I don't want the users to search for someone, see something like _krb_anonymous pop up, then think something is screwed up and call me and demand I come fix their computer!).
Any thoughts, suggestions, and such are more than welcome and much appreciated!
Thank you to all...
