I just thought of something. I can copy the program MAKEDEV from another system on to a flash drive, boot the FC6 rescue disk, mount the falash drive, make the make the device manually, and then do the restore.
It is amazing what you can think of if you are not in panic pissed off mode
I am worried now, 'cos a guru didn't know what /dev/st0 was and I did immediately, despite doing Linux for less than a year. I just read a post from a guy who put all his stuff on an external hard drive and had it die on him. I too have an old server with a SCSI tape drive (DDS3), and have it backed up (lucky, 'cos I trashed it by accident less than 3 hours after taking the back-up, and am left with a system which boots, but won't run the KDE GUI any more.) So I too want to know how to restore my system from the back-up tape, from the console. I have rebuilt it on another disk in the meantime, but have not got it back to where I was originally, with Samba working nicely, disks shared out and writeable by the Windows boxes on my network etc.
Its an HP ML350 with dual 600MHz processors, 1152MB RAM and 4 x 9GB disks running Mandriva 2006 Free.
Tape back-up is the way to go if you don't want to lose data. At work, I have responsibility for 75 servers in 6 locations round the UK and they are all backed up to tape 6 nights out of 7. Ask yourself why my employer (who is not a model of generosity) goes to the expense of doing that?
The flip side is that second-hand servers with working tape drives can be picked up on ebay for around £50. The ML350 was £45. I have just bought another for £50 (£20 for the server and £30 for the delivery!) so it is repeatable.
