Todays HDDs have a quite long life time. HDD manufactors usually denote the lifetime of their products by the MTBF value (mean time between failures). However, even if the model of your HDD is said to have an MTBF of, let's say, 50,000 hours, this may have nothing to do with your concrete instance of this HD model. It is just a stochastic value and never forget the meaning of the "M" in MTBF!
You must use at least three independent backup medias "round robin". Everything else is not worse to be called a "backup"! Think of a lightning bolt that crashes your machine just in the moment you are doing your backup. ZOOM! Everything is lost. Or the common virus infection, that is detected two weeks late...
And always keep at least one of the medias in a remote location!
Backup is a serious and important thing and really the wrong place to save money. You may say I am paranoid, but if the data is the base for your and your families likelihood one should really be a little bit paranoid about it. Everything else is just reckless.

One feature of VS is it prompts you to save your files before compiling.
I had just finished compiling, and lightning struck a major transformer for our province, triggering an overload, and shutting down half the province.
Except for our server room, which is UPS-run, city hall was down for 40 minutes.
On another note, I came back from a site with CDs in my jacket just as a bomb scare hit, and we evacuated to a nearby bar
It's been 4 years, and noone lets me forget how I "saved" the CDs.

I have all my source and documents stored in CVS on my linux box, which gets zipped up every night and secure copied to my office workstation and to a friends server, so I think it's pretty safe.
Even if Stockholm gets hit by EMP or something I will still be able to retrieve my backups from my friends server.

Sounds a bit like the Linus Torvald strategy
Once in an interview he told, that he never does backups of the Linux kernel. It is mirrored to hundreds of servers all over the world every 24 hours...

My test is if it can't fit on a floppy then i don't back it up. But this could be the reason for my receeding hair line. Me yanking my hair out everytime my system crashes and I can't retrieve the important docs

Do you remember the 8" floppies? That's what I call a real floppy

Is this a serious question?
Are there really developers out there who don't know what a floppy is?
Oh man I feel so old....

If disaster strikes the day before you backup, you would be a fool to _ever_ backup.

I find a good long soak in neat ethanol normally does the trick -- well at least then I can't remember what it was I couldn't remember.

My believe is that one need to backup at two levels. This is especially true when you work in small firm.
The first backup level should be performed daily (weakly) and the backups can be stored inside the firm (working enviroment).
The second backup level shall be done weekly (monthly) and the backups MUST be stored on a remote location -- another building.
If this sounds paranoic to you, image your office in a fire, which do not only destroy your HDD, but server, CDs and backup tapes as well
... or ...
a simple burglery that results in a loss of your computer and all backup CDs (nicely labeled and organized) that were stored on a shell above your computer.
We should not forget that in a true disaster you can lose several working years, either yours or your team's.

A friend of my is also a LAN administrator ad a company in the Netherlands. At one time their main server (PDS) completely crashed. Knowing they make a backup on a daily bases, no need to worry he thought.
The only problem was that he could not restore the tape (big progblem).
I think everybody has to check their backup tape on a frequent bases by restoring some files (I know, I do). I'm using Veritas Backup exec and never encountered any problems.

Daily...
In the little enterprise where I work the environment is hard, and there's a lot of iron particles floating in the air...
two of the four computers that are here have been completely destroyed: the hdd, the video card, and others have suffered and have been lost.
The first time the backups where made each month. And we lost only one month.
The second time we where making the backup daily, but then the HP COLORADO 5GB was not correctly handled by Win2k...
Imagine my life when I discovered (after calling to HP and Microsoft) that that streamer would not be holded any more. And that the internal program that comes with the OS save information to the tape, but is not capable to load information from it.
After all of this I have bought the Veritas Backup Exec program and now I'm running it... This seems to work properly.
Regards.

I would first get on the phone to Gateway then I would lament the loss of hundreds lines of code that didn't even compile anyway. My biggest loss would be my financial records but I backup that every time I update it(rare).

But all my documents, code, audio, video and other irreplaceable stuff lives on a 60GB mirrored partition so I would need to simultaneously lose two physical hard discs to lose the lot.

No you wouldn't - all you'd have to do is delete the wrong file, and POOF...
