"Find the needle in the haystack" does not work for me:

1.  It takes an unpredictable amount of time.

2.  Meanwhile, operations are stopped.

3.  Only one needle?  Really?

4.  How do I validate that the haystack is "correct"?


I keep my operating system images small enough to fit onto a single "16 
GB" device (USB flash drive, SD card, SSD, HDD, etc.) using BIOS, MBR, 
and no hardware or software RAID (lowest common denominator).  I take 
raw binary images of my operating system devices periodically and as 
needed.  I keep my operating system configuration files in a version 
control system.  I keep the vast majority of my data on RAID in a file 
server.  I snapshot, replicate, back up, archive, etc., everything and 
rotate backup media on-, near-, and off-site.  I have redundant and 
spare hardware.


When a system image is damaged or doubtful, I restore the last raw 
binary image onto a blank device, check out the configuration files, and 
restore local data.  The computer is back in operation in a predictable 
amount of time with a high level of confidence that everything is correct.
