"bru /"

This chugs along, then asks to insert a second 4mm DAT which I did, and
then gives:

c    746k of 1111542k [2] /lib32/rld
c   2330k of 1113872k [2] /lib32/libc.so.1
c      4k of 1113876k [2] /.login

c      2k of 1113886k [2] /._mmod
/usr/sbin/Backup failed (exit status 1), /etc/lastbackup not updated

Backup complete.
Backup interrupted

So why?

What I really want to know is what is the best way to do a complete
system backup?   Which program should I use (In case the disk gets
trashed I'd like to be able to as trivially as possible just load
everything it back - os, programs, user files, etc. -  from a 4mm tape).

Also, which programs can be used from the command monitor?

Herc

    xfsdump -o -f /dev/tape -l 0 /

The -l 0 is dump level zero.  Incrementals
would required -l 1, -l 2 etc...

xfsdump -I will produce a history report
from data stored in /var/xfsdump/inventory
when each dump is completed. xfsdumps can
be interrupted and resumed.

man xfsdump

Warning: if the system crashes, some older 6.2
CDs if I recall do not have the xfsdump/xfsrestore
combination in mini-root but an SGI tech would
know for sure.

        I have an irix 6.2 system with an xfs disk.  I wanted to do a full
        system backup.  According to the insight guide one should use the Backup
        program (which is a front-end for the bru program).  So I ran

        "bru /"

        This chugs along, then asks to insert a second 4mm DAT which I did, and
        then gives:

        .

        c      2k of 1110796k [2] /lib32
        c    746k of 1111542k [2] /lib32/rld
        c   2330k of 1113872k [2] /lib32/libc.so.1
        c      4k of 1113876k [2] /.login
        c      2k of 1113878k [2] /floppy
        c      2k of 1113880k [2] /.swap.virtual
        c      4k of 1113884k [2] /.profile
        c      2k of 1113886k [2] /._mmod
        /usr/sbin/Backup failed (exit status 1), /etc/lastbackup not updated

        Backup complete.
        Backup interrupted

If this happens, the first line reflects not
exactly what has been done and the second line
is wrong.

This may happen if some files were not backed
up like swap files or directories/files with
path names too long. Use the -v option of bru
to see which directories/files were not backed
up.

Interpret 'Backup complete' as 'Backup complete
as far as possible'.

Ignore the second line or change line 140 in
/usr/sbin/Backup from:
  trap 'cd /; echo Backup interrupted; rm -rf $tabfiles; exit 1' 0 2
to:
  trap 'cd /; echo Backup interrupted; rm -rf $tabfiles; exit 1' 2

        What I really want to know is what is the best way to do a complete
        system backup?   Which program should I use (In case the disk gets
        trashed I'd like to be able to as trivially as possible just load
        everything it back - os, programs, user files, etc. -  from a 4mm tape).

        Also, which programs can be used from the command monitor?

Why do you not use 'Backup' from the Toolchest
or /usr/sbin/Backup from the command moonitor
and in case of a crash SGI's Crash Recovery
procedure ?
