What exactly is your problem?

2. Why RAID?
There can be many good reasons for using RAID. A few are; the ability to
combine several physical disks into one larger "virtual" device, performance
improvements, and redundancy.
It is, however, very important to understand that RAID is not a substitute for
good backups. Some RAID levels will make your systems immune to data loss
from single-disk failures, but RAID will not allow you to recover from an
accidental "rm -rf /". RAID will also not help you preserve your data if the
server holding the RAID itself is lost in one way or the other (theft,
flooding, earthquake, Martian invasion etc.)
RAID will generally allow you to keep systems up and running, in case of
common hardware problems (single disk failure). It is not in itself a
complete data safety solution. This is very important to realize.
