As someone that just lost a OS build project last week, I remind myself the off-site physical copy and optical media do still have advantages.

1. kernel update on pre-release OS did something weird to the usb driver

2. heavily corrupted disk enters device hardware into lock-out

3. Pull ISO snapshot, and reinstall OS bare bone SSH install in Qemu session

4. verify OS working in VM

5. install new OS USB device in PC, boot once, and watch the kernel bug nuke the drive again

6. Boot from last weeks backup boot disk image, and watch the kernel bug nuke the drive again

7. install old kernel OS, and verify it was not a hardware failure

8. Remember to Backup, FOSS can byte hard when and not if things go sideways.
