storage solutions & backups

I'm getting into video (via new Panasonic HD camcorder) and am starting to rack up the Gigs in terms of movie files.

Also, more generally, at work my office disk will soon outgrow its 250Gb size, which is a RAID1 setup.

I'm looking to create some sort of BACKUP and REDUNDANCY functionality for the home setup (and enhance what I have with the work setup).

I've read the basics of RAID on wikipedia, so now I know that RAID1 is mirrored, but with no error-correction, so redundancy is built in.

But if we start with the home/camcorder situation:

I see that you can buy 1TB external drives now for less than £100. I'm not sure if you can get these set up as RAID(n), but if so I'm assuming they will be very expensive.

Maybe for the home/camcorder PC its best to just get 2x 1TB externals and plug em both in, have one be the working disc, and one be the backup?
How long will it take to copy 1TB from external disc #1 to external disc #2 (both plugged into USB ports) ?
Also to delete 1TB from disc #2?

(or is there a software solution that would turn disc#2 into a backup, so you didn't have to manually delete and copy - I guess so....?)
..and would there be a performance decrease by going thru' the software solution

ok guys, thanks a million, lots of great leads here.

Both of you mentioned enclosures and I found this on amazon, which looks like the best of both worlds. USB for connection to older systems and eSATA if I ever (probably will!) buy a new PC/server I can make sure it has an eSATA port. Do most new systems have them, or is it only high end ?

http://www.amazon.co.uk/StarTech-eSATA-External-Drive-Enclosure/dp/B001UEOG8M/ref=sr_1_26?ie=UTF8&s=electronics&qid=1238450965&sr=1-26

I then need 2x SATA drives to go inside. Will any spec do? or are there ones specifically made for going inside enclosures. The picture of the one SysExpert directed me to looks like it takes 2x cartridges of some sort, ie. don't look like your normal internal drives.

So if I get the enclosure + 2x drives, I then have a 1TB mirrored RAID 1 i can lug about with me.

But thinking, still like to do backups, so maybe another 1TB esata or USB to act as backup.

But I like backup where one can remove the media, and have a plan like days, weeks, months etc. Would a tape device be much slower than 1TB to disc ?
Can one get 1TB tapes (probably not i guess...) ?
