3ware RAID 1 card as a part of backup configuration
I am planning to use 3ware RAID card (3ware_9650se-2lp)with RAID 1 configuration for my mail server and I would like to make daily backups of entire system. I was thinking to use 2 x500GB drives in RAID 1 configuration and additional drive connected to SATA controller for backup of system installed on RAID 1 configuration. OS which I want to use is CentOS5.5 32bit and will be installed on RAID array.
My question is followed:
Is it possible to disconnect via terminal one drive from RAID array and mount it to running OS and then use dd or partimage and backup to drive connected to SATA controller
or any other tool which will make clone of this drive in case when RAID drives will crush
