Backing up dilemma

[SaltandSauce]

When first setting up my microserver server, I had full intentions of setting up a RAID array to ensure my data would always be recoverable if anything was ever to go wrong. Well.. things got a little out of hand and I no longer have any space with all four bays being used by hard drives that are completely full. The question is, what's my best option for backing up my data now?

As it stands, I have four hard disks weighing in at a total of 12TB. I really don't want to lose any of this data so if it means having to shell out cash then by all means, please recommend the best option possible.

Thanks

Apologies for bumping an old thread but I was wondering if anyone could provide me with some advice here. I'm still at at a loose end as to what to do. Can anyone please point me in the right direction?

My hard drives are all fairly new but I've had too many bad experiences where I've not bothered to backup and I've lost everything. This time round I'd much rather do things right. Even if it means having to spend the cash to replicate everything!

One other option if on-site backup is acceptable is to add an external SATA drive case to the microserver and add more drives in that.

This seems to be the road that I intend on going down. With so much data to backup, I don't think cloud storage is the way to go. Especially considering I'm only on a 3MB line. I haven't a clue what my upload speed is but I know it's slow enough that it's just not justifiable.

I've been considering spending the cash on one of the following: ICY BOX IB-3640SU3 4x 3.5 inch External 4-Bay JBOD Enclosure for SATA l/ll/lll HDD

Features
• Silent operation by thermal controlled fan
• Energy saving by supporting sleep modus
• Easy assembling by trayless design
• HDD capacity unlimited
• Supports: Windows XP/Vista/Win7, MAC OS X
• Plug&Play and Hot Swap
• Please note that a port multiplier is required for correct E-SATA functionality

What do you guys (and girls) think? It seem a sensible option if cost isn't an issue?
