Blessed be thy backups

The Holy Church of DWD compels you!

On the first day: thy operating system was installed
On the second day: thy configurations were applied
On the third day: thou bestoweth packages upon your system
On the fourth day: thy system become unbootable
On the fifth day: frustration set in, not knowing the root of the problem
On the sixth day: despair set in, the error message cryptic
On the seventh day: thy realization came to be that creating backups would have avoided three days of issues

Blessed be thy backups.
