I built my linux box out of left over junk in my closet, which includes;

1 big black Antec tower case & power supply (very quiet)
1 Gigabyte Nforce 250 mobo (very old)
1 AMD 3100+ CPU (also very old)
1 Gig of DDR RAM (I really have nothing to say here)
1 LiteOn DVD burner (same as above)
1 Nvidia 7600 GS 8x AGP card (w/512 meg)
1 gargantuan Nokia 445Xi monitor (which has seriously begun to lurk)

AND

2 Seagate SATA drives weighing in at 320 Gig a piece (they are indentical)

Maybe this sounds like more of a hardware question/post, but it won't turn out to be one once I actually start implementing your suggestions.

I accepted the default settings for the install on the first drive and now have a second drive called /dev/media which I can mount once I am logged in, no prob.

Can I, Should I, try to
1 mirror the first drive or,
2 load a bunch of distros on the second drive
3 create some sort of /srv test bed for web type stuf
4 create /pictures /video /Documents directories (or partitions)
5 use the whole 320 Gig to try my hand at messing around with Virtual Stuff in general?
6 use it for backups without mirroring anything
7 remove the drive and stick it in an equally lame Windows XP machine sitting next to it.
8 sell spare drive on ebay

What would you do if you had a spare 320 Gig drive just burning a hole in your pocket?

Fixed.

Drive that size, I might seriously work on learning open xchange myself. It's make a fairly decent backup space though for your other machines.

Well I just figured out that I cant mirror without getting a card and then re-installing everything so, no linux "dream machine" for me i guess.

I wonder if I should partition it or encrypt it for no apparent reason.

Here's a thought.

If I use it for backup, doesn't it make sense to be able to boot from it? to just swap sata cables and bring it up?

How close to mirroring can I get without actually mirroring anything?

I don't understand your first sentence cronjob, btw, AWESOME name!

You can always mirror with software..

You could use one as an encrypted drive to store your secure data. Although I would also want a STRONG back up of that. Because it is even harder to have a backup scheme for encrypted data.

You don't need to boot to a drive you use for back up. Unless you are trying to back up the entire system and have a "hot swap" system for getting back up with a cable swap after drive failure. Not really a big deal unless it is a production system.

I don't understand your mirroring question? You could use DD to make entire disk backups, but I have found that a more simple script is much easier to work with that copies or rsyncs data.

You can setup a live, hot backup machine, on the second drive. The setup is fairly complex but pays huge dividends in both redundancy and learning.

1. Setup two disks with identical partitions
2. install distro on disk #1
3. configure samba share and backup important files to this
4. mount partitions from disk #2
5. create boot files on /boot partition for disk #2
6. rsync complete system to mounted partitions on disk #2 (except /boot information, /proc, /sys, /tmp, etc. since these are virtual partitions)
7. when/if you lose the primary system you simply boot into the second system and have a mirror image
8. this can be done with any system setup, web server, database server, email server, etc.

If you do this on two drives the redundancy is reduced but does protect against drive failure. The real payoff is when this is setup between two live machines.

I edited my first sentence so, now your first sentence wont make sense but I meant to say that i can't mirror without a card.

I got my name at where I used to work because I had to keep running in the back ground just to stay alive. We played a lot of quake during lunch. Anyway, it's better than being called "Steph".
