data loss. For any serious computing task where data loss could occur, a regular backup
should be done.
For optimal security and safe work, you should make regular updates of all the operated
machines. If you have a mission critical server, you should probably run a second
identical machine where you can apply all changes for testing purposes before doing
so on the real system. This also gives you the possibility to switch machines in case of
hardware failure.
