I want to reinstall Mac OS 9 on my power mac 8600/250. I have aquired a retail disk and I want to wipe it clean. However it has some really old software on it and I would hate to get rid of it permanently. Also I would like the ability to restore to the way it is now if I wanted. Is this possible, can I backup the whole system somehow? I have copied the contents of the Hard Disk to my G5 as a backup that way, but I am looking for something I could use as a system restore, just like time machine. Does OS 9 have any feature like this?
