Help me choose a backup solution

So heres the thing, I have a 500GB G-Drive Mini, which backs up my uMBP, but thats now full. On it are a 200GB Superduper clone (i have a 100GB Bootcamp partition so my Mac OSX is <200GB), which i copy every week.

The other 300GB is mostly .avi movies, music, pictures. I foresee this expanding to 1-1.5 TB over the next 18-24 months.

I also backup to Crashplan Central, iTunes, Documents, Pictures, Mail and some of my movies.


In terms of what is MOST CRITICAL to me; id say probably the music, docs, pics, mail and maybe 80GB of actual media. So not alot that i couldn't live without.

As im about to buy a new external drive(s) i need to decide whats best.

I want at least 1TB of storage space but possibly 2TB. This will be used mostly for .avi files and other media files. Thus this data is not CRITICAL, however i would feel very crappy if in 9 months I lose 700GB of media, when my single backup drive dies.

Thus i am considering some more robust external backup solutions.

RAID0 is out of the question, its suicide.

RAID 1 would at first seem a reasonable and convenient idea, but everyone says im mad to think of this as a backup solution.

Thus im not sure what to do. Someone suggested two completely separate HD enclosures, and use one to backup the other and take the backup off-site. I agree this is very good but:

a) i cant be bothered with off-site 'material' backups for now. CrashPlan has 100GB of my most precious data and if every computer in the UK blew up, i would be ok only having that 100GB left (and losing everything else).

b) it seems a real hassel to backup to a separate external from another external, im looking for ease of use.


Alternatively I could get a dual bay enclosure and use JBOD and setup some sort of automated backup software to auto copy files from drive A to B. But i hear problems with enclosures can cause both drives to fail.


I guess, the below options are things i would be willing to consider making the effort to do;

A)

-Dual-Bay Enclosure (2x2TB) in RAID1
-Use my G-Drive Mini 500GB, to make a redundant copy of the critical files on the RAID1 configuration
-Continue using Crashplan Central (for 100-200GB of the MOST critical files)


B)

-Dual-Bay Enclosure (2x2TB) in JBOD, store my data on drive A, and then back this up to drive B
-Not use my G-Drive for another redundancy, as it is just too much hassel to manually make 2 redundant backups
-Continue using CPC (for 100-200GB of the MOST critical files)


C) (More Risky)

-Dual-Bay Enclosure (2x1TB or 2x1.5TB) in JBOD*, using both drives for the storing of my files
-Use G-Drive for redundant backup of the most critical 500GBs.
-Continue using CPC (for 100-200GB of the MOST critical files)

*Im saying JBOD as i believe using a 'BIG' configuration will crash twice as often is this correct?

Any thoughts guys. Cheers

 

Very impressive stuff, but im wanting a FW800 connection, and i cant see any on their models costing less than £600.

I have a budget of around £300
