Answer 1

As far as backing up your calendars, I use the A/S below (scheduled daily) to backup my calendars. It places a copy of (~/Library/Calendars) in your (~/Library) folder.
Can be modified to locate the backup to an external drive if desired.
--pick up directory path
set WhoAmI to ((path to library folder from user domain) as string)
set the_date to date string of (current date)
tell application "Finder"
     --make our backup folder if necessary
     if not (exists folder (WhoAmI & "CalBackup")) then
          make new folder with properties {name:"CalBackup"} at folder WhoAmI
     end if
     delete every folder of folder (WhoAmI & "CalBackup")
     delay 3
     make new folder with properties {name:the_date} at folder (WhoAmI & "CalBackup")
     duplicate files of folder (WhoAmI & "Calendars") to folder (WhoAmI & "CalBackup:" & the_date)
     --check file sizes
     set FileList to every file of folder (WhoAmI & "CalBackup:" & the_date)
     repeat with ThisFile in FileList
          set TheSize to (size of ThisFile) / 1024
          if TheSize < 0.2 then display dialog ((name of ThisFile) as string) & " may be empty" with icon caution
     end repeat
end tell
Copy the script and paste it into your Script Editor. I saved it as an app called "iCal Backup" which I schedule to run daily.
