Hi yet again, (1) sda sdb confusion:
Hadn't ever experienced sda and sdb changing assignments in my system -- except one period years ago when the pin contacts on my IDE/PATA caddies got a bit wonky. In my backing up system, I'm clear about the physical location of master and backup drives, and include a visual (LED-on) confirmation of drive assignment before the shell script starts the RSYNC command. First time using SATA. Hope it doesn't introduce any randomising factors. (2) LABEL a possible bullet-in-the-foot: As every single file and directory is copied in my backup system, it may COPY the master disk label on to the backup disk, creating a dual identity problem from then on. But if it does NOT copy the label across, then the backup disk would not boot (in a restore situation) due to an invalid identification problem, similar to the UUID that I'm working around. Thanks for thinking about it, though. Carl p.s. And =still= no one has actually commented on the adequacy and accuracy of the proposed editing in the boot-up configuration files in my original post. Sigh. On 22/04/14 13:03, Daniel Jitnah wrote: > > > On 22/04/14 12:14, Trent W.
