I have a question about backups. I recently tried to move my calendars from an Ubuntu based server to one based on Debian (Lenny). I had assumed that I could simply install DCS on the Debian machine, copy over my data and configuration files, restart the server, and be done with it. On a client machine, I deleted the old accounts (before first sync), then input the account data info again. My expectation was that the client would suck the data off the server and repopulate the calendar, except that when I would do this, I ended up with no group calendars. In Apple's iCal, I would have an entry in the left pane for the group name as I set it in Account-Preferences, but no calendars at all, not even empty ones. On the server, I copied the files with the "preserve" flag from the HD of the Ubuntu system, and did a chmod/chgrp to "caldavd". After much fooling around, I figured out I could create a new calendar, then import all the *.ics files from a user's ~/Library/ Calendars/CRYPTIC_STRING.caldav/2nd_CRYPTIC_STRING.calendar/Events into the newly made calendar. This would then transfer the calendar data back to the server. Once this was done, I could sync with DCS from a different computer (accounts newly setup) and the data would transfer from the server to the client. I have a backup script that runs every night on the server, but the client machines are a mix of laptops and desktops and I don't really want to hassle with backing up the calendars from each of those. I'm concerned however, that I may face serious problems with restoring the calendars if I ever have to make use of the backups because of my experience in copying from one HD to another. So my question, what should I be saving in my backups? I'm saving the config files in /etc/caldavd and the data from /var/spool/caldavd.
