Hello:

I want to back up several dir s located on different slices on a tape. I
read Solaris doc, but I don't find a right solution. Examples are how-to
backup A dir from A slice on a tape, and I would like to know...

How-to backup from /var & /etc from a slice and /export from another one
on the same tape...

How-to read tape after back-up to know if it's the right one (before to
recover).

How-to restore A selective dir from multiple dump tape.

Thanks on advance

To put multiple things (dumps, tars, etc.) on the tape, use the
no-rewind device names and use the mt command to position the tape.

#
# Multi volume backup to single tape (such as 8MM Sun X6212A) using ufsdump.

if [ $# -ne 3 ]
then
  exit 0
else

   level=$1
   tapepos=$2  # Suggest you should always start with 1
   logfile=$3

  df -F ufs | grep dsk | awk '{print $1}' | while read fsparms
   do
    mountpoint=`echo $fsparms | cut -d" " -f1`
    device=`echo $fsparms | cut -d" " -f2`
    echo "Backing up $mountpoint ($device)" >> $logfile
    /usr/sbin/ufsdump "$level"unbdsf 126 54000 13000 /dev/rmt/0hn $device  2>> $logfile
   if [ "$?" -gt 0 ]
   then
    echo "Level $level dump of $mountpoint on $device was NOT successful at tape position $tapepos" >> $logfile
   else
     echo "Level $level dump of $mountpoint on $device was successful at tape position $tapepos" >> $logfile
     tapepos=`expr $tapepos + 1`
     echo $tapepos > /etc/last_tape_position
   fi

The above script will backup all "ufs" file systems.  Run it like:

do_backup 0 1 backup.log

If you had partitions /, /usr, /var, and /home. / would be position 1, /usr
position 2, and so on. To restore from the /home sequences (4) use the command:

ufsrestore ivfs /dev/rmt/0 4

If you only wanted to do a selected list, it can be done from the command line
or place them in a file and execute it, like:

/usr/sbin/ufsdump 0unbdsf 126 54000 13000 /dev/rmt/0hn / ; \
/usr/sbin/ufsdump 0unbdsf 126 54000 13000 /dev/rmt/0hn /usr ; \
/usr/sbin/ufsdump 0unbdsf 126 54000 13000 /dev/rmt/0h /var ; \

to restore from /usr you would:

ufsrestore ivfs /dev/rmt/0 2

See:

man ufsdump
man ufsrestore
man mt

for further detail.
