[CalendarServer-users] moving calendars

[John McAdams]

I was able to move my calendar to a new host.

I used "tar cvf" to archive the old calendar. The archive was moved  
using the Mac OS Finder to a USB drive. Then a Remote Access copy to  
the new computer on a different network. I unpacked the archive on the  
new host.

My calendar had already been established on the new host. I put the  
old .ics files into my calendar/username folder. I ran "ls -l@" and  
all the old xattrs were present. The username and group had changed  
however, so I set them back to _calendar:_calendar. I refreshed the  
calendar on the client and the appointments appeared.

This is great. Moving and restoring files is simple if all the  
attributes are intact.

Next I'd like to set up some rsync scripts for backup. If anybody has  
some sample scripts please post.

Best regards,
