Michael, you have a really bad habit of starting new threads using
existing subject lines. Please start new threads with original posts
and pertinent subjects.
That said, here's a script I use for weekly backups to tape. On Monday,
it does a full backup to tape. Tuesday through Saturday, it does a
differential backup of any files changed in the last 24 hours. On
Sunday, it does another differential backup and rewinds/ejects the tape.
#!/bin/bash
YESTERDAY=`date +'%d %b %Y'`
DIRS="/etc /home /root /var"
START=`date +%s`
echo "*** Starting Backup - `date` ***"
if [ `mt -f /dev/nst0 status | grep -c ONLINE` == 0 ]; then
# Drive not ready
echo "Drive is OFFLINE, exiting!"
exit 1;
fi
find $DIRS -type s > /tmp/backup-sockets.list
if [ `date +%u` == 1 ]; then
# It's Monday, let's erase and do full backup!
mt -f /dev/st0 rewind
mt -f /dev/st0 retension
mt -f /dev/st0 erase
tar cpf /dev/nst0 $DIRS -P -W -X /tmp/backup-sockets.list
elif [ `date +%u` == 7 ]; then
# EOW, let's do an incremental and eject
# Let's do verbose on the incrementals
tar cpf /dev/nst0 --newer "$YESTERDAY" $DIRS -P -W -X
/tmp/backup-sockets.list
mt -f /dev/st0 rewoffl;
else
# Let's do an incremental backup
# Let's do verbose on the incrementals
tar cpf /dev/nst0 --newer "$YESTERDAY" $DIRS -P -W -X
/tmp/backup-sockets.list
fi
echo "*** Backup Complete - `date` ***"
END=`date +%s`
DIFF=$((END - START))

echo -n "***** Total Run Time: "
HRS=`expr $DIFF / 3600`
MIN=`expr $DIFF % 3600 / 60`
SEC=`expr $DIFF % 3600 % 60`
