Backup vs RAID 1

I'm expanding a home server that has software RAID 1 (data only), and was wondering if RAID is overkill.

I was thinking of using a backup strategy instead, since files don't change often and I'm constantly reading from the drives.   I have close to 1TB of data, so optical backups are not feasible.  I know that RAID 5 takes a hit in performance, but what about RAID 1?  I'm interested in what people are doing at home.

Thanks.

Re: Backup vs RAID 1

If performance is important, you better invest in IDE/SATA RAID controller, which is not expensive (when comparing to SCSI).
And if you got the $$$ to replicate 1T of data, software RAID1 is certainly not overkill for a server... my workstation's root partition is on RAID1 (rest is RAID0).
RAID5 will be faster than RAID1, but its all about $...
