If you think that a RAID exempts you from the backup burden, you're wrong. I'm honestly sorry for your loss (having gone through that hell before, far many more times than I should), but discouraging the use of RAID because you didn't back up your data is misleading.
That being said, I
strongly discourage the use of any kind of RAID for home use. RAID in its simplest definition consists of sacrificing disk space for higher uptimes. Having a 99.99% uptime isn't important for most (all?) home uses I can think of.
RAID does not in any case dispense you from proper backups. All you're left with is a huge part of disk space wasted and that can amount to extremely costly systems.
@MohammedSF: Based on what I've written (and common sense), there's
absolutely no reason for you not to back up your data. Even if it's costly and it takes a long time, back your data up before you regret it.
And depending on your use:
- Either you're talking about your home system, and as mentioned I suggest you get rid of the RAID
- Or you're talking about enterprise systems, in which case you need the RAID, but you have even more reasons to do (incremental) backups.
