If KBACKUPcannot find a valid header on your backup medium, although
you have written an archive to it using KBACKUP, than there are
two possible reason for this:
-
you are using a tape
device that rewinds after closing a file. KBACKUPrequires you to
specify a device that does not rewind on close. These devices
often carry an ``n'' in their name. If you try using a device with
rewind-on-close feature, KBACKUPwill overwrite its header with the
directory and afterwards overwrite the directory with the actual
archive, instead of writing the files one after another.
-
You might not have started your backup at the beginning of the tape.
The automatic verify after a doing a backup will rewind the tape
before verifying the backup, it will not automatically rewind
the tape before writing the backup (for reasons of security). So try
to manually rewind the tape before writing the backup.
In version 1.2.3, I have introduced an option to check a tape device for
compatibility with KBACKUPand also autodetect the proper device file.
