Any drawbacks to this idea?

A real backup strategy needs at least three generations of data stored on independent media stored at different locations or (at least) in a fire resistant place. You are lost, if:
- Your data is corrupted by a virus, accidentaly, sabotation or similar things, and you notice this after doing the backup.
- Your house is burned
- A lightning strike or an electricity problem destroys both machines at the same time
- ...
It depends on the importance of the data if you can live with this.

Can't be said enough.
Assume your business will burn down.
Most people don't have a media quality fire safe. A normal fire safe will not work with media. A normal fire safe is rate for such things as 400F for 30 minutes where media quality fire safes are rated at 100-150F for 30 minutes. Media won't last long in a fire safe rated at 400F for 30 minutes.

At least 2 or 3 times a year it is a good idea to make sure you get some hard copy backups to locations outside of your current country. You never can tell when a serious war will break out. If all of your off site backups are in the same country or, even worse, the same city, you could be at serious risk from nuclear attacks, or even traditional fire bombing.
The idea is to play it safe. Once sufficient data storage is available elsewhere in the solar system, regular off-Earth backups will probably be prudent. You don't want your data to be caught off gaurd by armageddon. Lets make sure that our code outlasts humanity!

Our company is working on such a device.
We are working on lasers to write 137 bit encrypted data onto the moon's surface, much the same way as a CD Writer works. A similar technology is used for reading the data using lunar geostationary satellites.
Lunar backups will be a big thing in the future.

Wow! Finally a *good* use for that rock. But, why 137 bit? Won't the aliens living on the dark side find that rather easy to crack (what with their alien tech and all)?

Unsure about the aliens Shog9 ... but the 137 bit cipher block riddle has been around for a while, and I doubt anyone has any notion still of how it's to be cracked.
The thing is you can easily encrypt data, but decrypting it is still impossible AFAIK.
I think another name for is the T16++ bog.

Ah, thanks for the info Colin. I couldn't find any info on it searching Google for some reason, and that Buck was being all mysterious about it.

Not me, I will have my data safely stored on several servers in Mars orbit.

yup.
i do a full backup and take it to a safe deposit box once a month. weekly backups stay with me at home.
(don't forget to archive a copy of the backup software, too ! )

We in Germany (Saxonia) have yet a flood greater than the "Sächsische Sintflut" (Saxonian Flood*). *Flood in the bible
Its real desaster which no-one has ever expected. Many people lost everything. Imagine your house and everything in it is washed away!!!
So there is an outside backup essential!!!
CD may worked with this water desaster but a fire would destroy them quickly.

As stated in the title, didn't we do a "How often do you backup your data etc..." survey a while ago, so why another one so soon?

Maybe this is a backup poll

That was 'how often', this is 'how'.
Suffice to say that last one was due to me *almost* losing data, and this is because I was thinking about how best to actually backup my data now. Two sides of the same coin.
cheers,

I think that first two options (Copy to a spare drive/partition and Copy to a network share) are not actually a methods of backing up but just making a copy.
You can as well copy files to another folder - most likely in the event of data loss you will loose partition, and if you are attacked by virus you may loose network share contents as well.

Network shares are not the only way to copy from one computer to another.

I see there are a big portion of ppl use spare partitions/network share for backing up data, and like most of you, I used to backup my data in that fashion... but with recent attacks (or attemps) from the nasty Nimda virus, I only back up my files on either CDs or SCP to my *nix (FreeBSD) box now...
Call me paranoid, but I'm not taking any chances...

Of those who chose this option, what are your experiences like?
It is feasible for us to use this method for our hosting server as it is in a high-bandwidth location, but not for our actual offices as they have just ISDN or DSL connections, nowhere near fast enough for remote backups.
So just curious if remote online backup works for you and what kind of bandwidth you require to use it.

Source is developed on my laptop or desktop machine.
It's archived under source-safe.
Back-ups stored on a seperate machine. (In zip and uncompressed format)
Backed up onto CD/DVD (which is then kept at another location)

Source code is almost the only thing Ih ave on my machine worth backing up. Hence a source control system (currently PVCS.) Works well in two ways - if my machine goes down, the files are on the server. The server gets backed up to tape or something. But even if it did go down, and we lost all our backups, we could piece together the whole set of files from what's on our macines.
This is an occasional Word document that gets in there, though.
You are special and unique, just like everyone else.
