I was backing up some user directories the other day on a cartridge
drive, and came upon a problem. First, I did
wbak -dev ct -f 1 //blah/blah/blah
then I did
wbak -dev ct -f cur //blah/blah2
The tape rewound itself politely, and proceeded to write right
over the first file. It seems that -f cur always means -f 1
on the cartridge drive, or in wbak.
If you've got an automated archive system that writes a backup
and then deletes the directory, -f cur was a nice option
with our 1/2" tape drive. Luckily, I didn't just change the
mt to a ct, or I would have automatically deleted many user directories.
Is this a bug or a 'new feature'? Has anyone else noticed this?
Should I send in a UCR?
Thanks,

I use -f cur when making cartridge tapes all the time, but I also use a -no_eot switch for all but the last file. Maybe this is your problem? -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter@eddie.mit.edu krowitz%richter@athena.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)

This option suppresses double end-of-tape marks for cartridge tapes. The first wbak should be wbak -dev ct -f 1 -no_eot //blah/blah/blah and the second one should be wbak -dev ct -f cur //blah/blah2 -- Roger E.
