28 Software Manual
-z[=<filename>] Reads an exclude list. None of the files/
subdirectories in this list will be treated. Note that the
full pathname of each file/directory is required.
Wildcards ('*','?') are accepted. If <filename> is
given, back will read the exclude list from
<filename>, otherwise it will be read from the
standard input path. Input from standard input path
can be terminated by <ESC>.
-o[=<filename>] Reads a select list. Only the files/subdirectories
included in this list will be treated. For more details,
see the '-z' option.
-f[=<filename>] Formats destination device. <Filename> is the name
of a command file, which is forked by back.
This file has to contain a command line like:
format /d0 -npnvnfr. The default command file is
/dd/SYS/format.back. Tapes should always be
erased prior writing first saveset.
-b=<num> Allocates <num> KB of memory for copying. Back
uses 100KB by default.
-p Asks before copying.
-q Doesn't ask before copying (default).
-x Debug mode
-l Lists names of the files in the saveset.
(Works only on saveset)
-v Verifies the files in the saveset.
(Works only on saveset)
-a Writes a saveset in block mode.
-c Fills last block to complete buffer size.
-k Doesn’t overwrite existing files (copy and rename
first).
The following options only make sense if destination is not a saveset.
-r Writes over existing destination file with same name
without asking.
