I'm setting up a small editing system for an important job. I am super afraid of having a breakdown of a Hard disk. I want to use Lacie firewire 800 disk for media files, and maybe the internal ATA for sound and program files. My question is:
Since I can have 2 internal Hard disks in my G5, can I then clone the startup drive which also could contain all program files, documents and so on? So that every time I save something to my internal HD it gets automatically saved on the clone disk.
Can I do the same with my external firewire HD? So that it automatically send a copy onto another disk.
Is it possible, because then I will have a fail safe system with everything backed up all the time? Will the system get slower?
You didn't mention which system, but using Carbon Copy Cloner to copy, file by file to an external Firewire drive, should be able to boot off the Firewire drive in case of emergencies. If you need to run DiskWarrior without booting to the CD, you can boot the Firewire copy and run DW on the original disk drive.
You want to use RAID Mirroring. This will maintain the exactly the same thing on two matching drives. Not slower but you only have one half the storage. I think the drives need to be the same size. You can do this with Disk Utility or third party software. You will need to back everything on the drives before setting up the Raid Array.
