Hi, I have been using a Conner floppy tape for 4 years to do this... > When I run the command 'dump -f /dev/rft0 /usr', I get the message "DUMP: > bad sblock magic number" and dump quits. The floppy tape support is different from standard tapes, you need to use the program 'ft' to access the tapes. The standard 'ft' program is pretty limited (it only allows a single archive per tape) but some years ago an improved ft called lft was posted to the lists (search for it on the lists or mail me directly for a copy) that allows multiple archives on a tape. With the lft (or ft) program you can dump like this: dump /usr | lft -a OR dump /usr | ft > Does dump support floppy tape drives, or am I missing something? > Also, does the 'ft' command (ala, 'tar cvzf - /usr | ft "/usr save"') > support multiple-tape spanning? Yes, as does lft. > I'm a newbie looking for a quick, simple way to backup before I make world > and build a custom kernal. Any help would be greatly appreciated. Simple you get, but I have never called my floppy tape quick....
