The Little Snitch feature meant that we would have to be hands-on with the server any time we wanted to be able to boot from a clone. Unfortunately it also derailed our backup/recovery plan, which needed to work without physical access to the machine. This authorized the cloned rules file which allowed for the remote access and we needed. The short-term fix was simple – we simply had the onsite tech click the "Use Current Version" box). It makes perfect sense – Little Snitch was making every possible effort to secure the machine. When the machine booted from the clone Little Snitch was smart enough to see that it was looking at a different rules file and it went into a kind of safe mode that blocked all external connections. This is a security feature in Little Snitch. This required a call to the colocation facility where the tech on duty sent back this image: We could not get ARD, SSH or any other access to the server. Using Apple Remote Desktop (ARD) we accessed System Preferences, changed the Startup Disk to the clone, hit restart, and waited for the machine to come back online and be available in ARD. The plan was to start up from the selected clone, confirm that it was good and working as expected, then clone that back to the primary boot volume. Recently we had a serious problem on one of the servers and it looked like the best solution was to restore from a clone. So Little Snitch helps protect the machine and Carbon Copy Cloner makes sure we always have lots of backups to work with. #Carbon copy cloner mac macThis, just part of a bigger backup/recovery strategy, was inspired by a great post on backing up Mac servers from the people at. If faced with a server failure we can simply get a new server in place, connect the external drive, and then boot or restore from a clone. These clones are saved to partitions on an external hard drive. This allows us to restore files from these clones, boot from them to fully restore to a cloned backup, or (in the event of damage to the boot volume) clone a cloned backup back to the boot volume. It is scheduled so that we always have seven daily backups (one for each day) and four weekly backups. #Carbon copy cloner mac softwareMuch of our peace of mind when it comes to security and backups comes from the use of two great pieces of software:Ī fantastic utility with many applications that we use as primarily as a software firewall.Ī fantastic duolication utility that we use to create clones of the startup disk on a regular basis. We configure and work on those using Apple Remote Desktop (ARD) and SSH. #Carbon copy cloner mac mac os xWe run two Mac OS X Servers in a colocation facility. But, if you aren't careful, you can lose all remote (including HTTP/FTP/ARD/SSH) access when booting from a clone (created by Carbon Copy Cloner) of a startup volume (that runs Little Snitch). Mac OS X Server, Little Snitch & Carbon Copy Cloner May 03, 2015Ĭarbon Copy Cloner and Little Snitch are awesome tools for anyone running Mac OS X Server.
