Sure, raid 5 protects if a drive fails.. but is that all you're worried about? what if the rebuild fails, or if you needed something you accidently deleted (don't go all high and might saying you never delete something by accident either, it's just a senario)?
Really just curious. I think RAID5 would be probably enough in all likelihood, but it's much too expensive to get a hardware raid 5 controller.. the one my friend had.. was slow as balls in writing.. something like 10MB/s 🙁
I don't backup the array. For the price of the backup hardware, I could triple the capacity of my array. I do take some precautions to protect the data. Any user can write files to the array, but every morning at 3am, a cron job sets security so only the root user can modify the files. This prevents a virus or whatever from doing too much damage. This sounds restrictive, and it is, but considering the array holds video files and backups, not files that are often changed, its not a problem.
As far as deleting something accidentally, on this array, it probably wouldn't happen. Generally, a file is copied to the array, renamed, security applied, and then its just read. On my Windows servers, I use Volume Shadow Copy for that situation, plus those servers get backed up to the big server weekly.
Speed isn't an issue, really. I ran some bonnie++ benchmarks when I first assembled the arrays and got about 50mb/sec writes and over 100mb/sec reads. Hardware RAID controllers can be fast... the 7506/8506 and better 3ware cards are good, as are the Areca line of SATA raid cards.
the speed comment was merely something my buddy did.. but he was using some hardware scsi raid controller w/ IDE convertors or some weird sh!t. I just tend to be overly paranoid w/ my data.. heh
