- DON'T WORRY, SUNDANCE, I'LL BACK YOU UP
- by Harry Ingham, WLAKUG, August 1987
-
- (An almost realistic look at backup philosophy)
-
- Every judgement is also a judgement on yourself, and every piece
- of advice is also advice to yourself. So, this article is a
- message to me, and I hope I pay attention.
-
- Here is the normal, rational backup strategy. Well, actually,
- it's an obsessive, bizarre backup strategy, but never mind:
-
- First, if you have a problem with power interruptions, you need
- to save your work to disk with great regularity. People will
- forget to tell you that the electrician is here, and Zeus will
- forget to tell you that he is about to hit the city power system
- with a lightening bolt. Most people are pretty good about saving
- to disk.
-
- Second, what is on disk is not necessarily eternal. Zeus may
- have your house in mind, in which case, since you naturally want
- your work to survive your death, so as to benefit mankind after
- you are gone, you need to make a copy of your work, and stash it
- with a friend who lives farther from you than the usual radius of
- destruction from an atomic bomb. Most people are terrible about
- making backups.
-
- Third, if you should accidentally survive, you need some sort of
- filing system. Neither you nor anyone else is likely to read
- every text file and unpack every data file to find one item of
- lost info, so it might as well be erased as unfiled. MASTCAT,
- SD, NULU, etc., will provide the basis for a filing system, or
- you can try to build some sort of index on your own. You will
- NOT remember that RUJW4G.TXT means the recipe Uncle John's wife
- forgot. Most people are medium-good at filing systems.
-
- Fourth, just remember the sequence of actions in case your house
- catches fire. First, throw your disks out the window, THEN jump.
- After all, what good are you without your data?
