Quick format is a formatting option that creates a new file table on a hard disk but does not fully overwrite or erase the disk. A quick format is much faster than a normal format, which fully erases any existing data on the hard disk.
When you do a back up, you copy, then you remove the cable and store it somewhere else. It means it is more secure. If you make 2 copies in 2 separate HDD, it gets even more secure. If you take one of the backup drives and store it at your office, you are now super secure.
Having RAID is just high availability (just to make sure system is still running when a HDD fails), it has nothing to do with any backup strategy.
RAID is not data backup
A RAID system used as a main drive is not a replacement for backing up data. Data may become damaged or destroyed without harm to the drive(s) on which they are stored. For example, some of the data may be overwritten by a system malfunction; a file may be damaged or deleted by user error or malice and not noticed for days or weeks. RAID can also be overwhelmed by catastrophic failure that exceeds its recovery capacity and, of course, the entire array is at risk of physical damage by fire, natural disaster, or human forces. RAID is also vulnerable to controller failure since it is not always possible to migrate a RAID to a new controller without data loss .
RAID drives can make excellent backup drives, when employed as backup devices to main storage, and particularly when located offsite from the main systems. However, the use of RAID as the main storage solution cannot replace backups.

Anyway, I think all of us have gone OT enough. And I think TS has already solve his/her problem.
