Backup/Restore process is actually better than a disk clone as it allows for one to remove the older cruft, upgrade the OS, switch hardware, etc.. yet all the Apps and Cloudron instance settings work as originally backed up.
Very handy and a seriously difficult thing to do, hence the many disk imaging and other schemes to try and replicate a nicely configured system, which quickly become out of date, being so static.
Cloudron FTW! 😄
