b) Make backups on disks using a saveset:
$ back /h0/SOURCES -s=/d0/savesource >/h0/backout&
Back copies all files from /h0/SOURCES into one saveset named
savesource on disk. The saveset will be copied into the root
directory of /d0. In this case back will work in the background and
redirect standard output to /h0/backout.
$ back /h0/SOURCES -s=/d0/savesource -z=exclude
The file exclude may contain the following lines:
"/h0/oldprog"
"/h0/PROGS/*.c"
"*/CMDS/*"
Back copies all files from /h0/SOURCES into savesource, except
for /h0/oldprog, all C files in PROGS and the files in all CMDS
subdirectories.
c) Make backups on tapes:
$ back /h0 -wft
Back copies all files from device /h0 into the saveset save_1 on
streamer device mt0. Prior to writing to the tape, it will be erased.
That is the way to backup to a tape without data on it.
$ back /h0/SOURCES -t=/h3/savesource
Back copies all files from /h0/SOURCES into the saveset on tape.
The file is written to the end of data area.
$ back -t=/h3/savesource /h1/SOURCES -w
Back rewinds the tape ('-w') and restores the files on
/h1/SOURCES. The original file structure will be rebuilt.
$ back /dd -t=/mt0/harddisk -wv
Back rewinds the tape and compares all files stored in saveset
'harddisk' with files on device /dd.
