Hello,
I would like to replace one of the disks in a raid 1 array (software raid) in centos 4.4 for the purpose of saving the removed drive as a backup of the system. Replace it with a new disk and have the raod resync. That way the removed disk can be used to restore the system to that point in time if something dramatic occured.
I have a number of questions, I can’t find the answers to and I don't have a system I can play with to see how the software behaves:
1) Do I need to partition the replacement drive or will the system do it after reboot? 2) Should I break the raid before replacement or just shutdown, replace and reboot? 3) I have also read that acronis 10 rescue CD can be booted and take a system image that way but I have not tried that yet..
In general, are these approaches a good idea for generating an offsite image backup??
Any help or input would be appreciated.
Thank you,
