Backing up my MacBook Pro and my desktop... I have ideas

[alfa147x]

I need some way to back up my laptop and desktop. Here is my plan:

MacBook Pro: will have a 500GB Seagate Momentus XT and later a 5400 rpm 500GB HDD to do a 1:1 back-up on to every night kinda like a delayed RAID 1

Could I do a RAID 1 with no / very little performance decrease? Also why is the cost of a 250 GB almost the same as a 500GB Momentus Hybrid? I only need about 250 GB of storage on my MacBook Pro :\ I only use it to editing photos on the go and class... Or should I go with 2x 250 gb 7200 HDDs in a RAID 1? That would be about a $100 cheaper.


Desktop (Hackintosh): has a 500 GB HDD right now I'm thinking about dropping another 500 GB HDD in it and run it in a RAID 1

For both I plan on getting a 1 TB G-Drive to back up just my picture library on to.

Anyone see any flaws with this plan? Any places that things can be done better?

Also eventually I will need to get a copy of the 1 TB G-Drive off-site any recommendations on how to?

Thanks folks,

For my backups, I do both Time Machine and SuperDuper. Time Machine runs hourly. SuperDuper runs every night. I do it this way because Time Machine is non-intrusive and automatic, while updating a system clone with SuperDuper can take more time, and isn't something I want to have happening while I'm in the middle of using my computer.

For your laptop, getting a drive bay in place of the optical bay is the best route to go for convenience - then your backup is always *in* the laptop and you never have to remember to plug anything in when you get home, or leave your laptop on at home on WIFI so that it backs up to a Time Capsule.

RAID 1 is a good thing, but it doesn't replace a backup system - your data is twice as protected, but if you delete a file, you still can't get it back with a RAID 1 system - still gone forever!
