tar
method do not contain the owner and
permission information of the stored directories.
If such an archive is restored, the directories created by tar will
get some default permissions. The permissions of the files in the
directories will be restored correctly. Thus bug makes the tar
method useless for creating real backups.
To circumvent this bug, install cpio and use the tarcpio
pack
method instead of tar
.

during a failing write will shorten this time, but it may
remain extremely long nevertheless.
In particular, be careful using floppy disks that were formatted by
the MS-DOS Central Point Backup
program. If these floppies were
formatted in the CPS floppy format
in stead of the normal `DOS
standard format', they are not suitable for direct use by tbackup
but need to reformatted first by switching on the `always format
inserted disks' option.
Tbackup has no way of detecting the CPS floppy format
if such a
disk is inserted: it will think that it is a correctly formatted
disk and start writing to it. Of course this write operation will
fail, but tbackup (the floppy drivers) will take an insane amount
of time (probably hours, I have not checked this) retrying the
write before reporting failure.Next Chapter, Previous Chapter
