I have a Ubuntu 16.04 as my webserver, now that i have everything ready and working is it possible to create some sort of image/backup/clone so that if i mess something up or want to test new versions that i can restore to this current state?
Example 1, i clean install Ubuntu 17.10 for testing, and after that i will go back to the system 16.04 with all settings/config i have now running.
Example 2, my VPS gets broken or crashes, i can reinstall Ubuntu again but then also need to configure all partitions settings etc again. Is it possible on a clean install to use some sort of iso/clone that sets back my current runnig system over the fresh install?
