Break Mirror raid?

[rstgermain]

Hi there,

maybe this is a silly thing to do but my question is...I have a mac mini server with 2 500GB drives in a mirror set. If i break the mirror set and boot from one of them and install an update and an update breaks the system technically could i boot from the other drive and rebuild the raid?

Technically may be possible, but I don't recommend it. RAID is not a backup solution it is a redundancy/high-availability solution.

Things like ESD (Electro Static Discharge) could damage the disk you remove without you even realising it.

If you want a bootable backup, use SuperDuper or Carbon Copy Cloner to create a bootable clone.

Or if you simply want a backup use Time Machine.
