if you read the man pages for your particular backup command they offer a common backup stratigy.
Personaly. I find it much easier to do a level 0 dump every night.
We are a 24/7 shop.
Code:
solaris backup script
$ cat /var/adm/scripts/backup.ksh
for i in / /home0 /home1 /home2 /home3 /home4; do
/usr/sbin/ufsdump 0uf /dev/rmt/0n $i
done
mt rewoffl
Code:
AIX backup script
$ cat /var/adm/scripts/backup.ksh
#! /bin/ksh
#
# This script is intended to be used on AIX 4.3.3 and 4.3.2 ONLY.
# This will use the backup utility doing a level 0 dump on any filesystem defined for $filesys and update /etc/dumpdates.
# Arguments:
# DEVICE = <backup device> rmt0 = rewinding rmt0.1 = non-rewinding
# DUMPINFO = <file that will collect info to be emailed out>
# MARK = <possition on the tape>
#
DEVICE="/dev/rmt0.1"
DUMPINFO=/tmp/dumpinfo
FILESYSTEMS="/ /usr /var /home"
MARK=1
echo > $DUMPINFO
for filesys in $FILESYSTEMS; do
echo "Date: `date`
Filesystem: $filesys
Position: $MARK
Device: $DEVICE
" >> $DUMPINFO
/usr/sbin/backup -f $DEVICE -0 -u $filesys
MARK=`expr ${MARK} + 1`
done
cat $DUMPINFO|mailx -s "Dumpinfo `hostname`" root
sleep 20
mt -f $DEVICE rewoffl
some files systems have been omited. but you get the gist.
1) well if you have more data then what can fit on 1 tape. you can also do a multivolume dump.
so you will use 2 or more tapes for your backup and i would highly suggest that you mark the tapes as to which volume and place your specific data is on.
you can also do backups w/ the tar and cpio commands. instead of taring to a tar file you tar to a device.
Well.. let's say i need to write a pretty simple script.
In my script i have 2 variables which can have value of 0 or 1.
$VERBOSE
$LOG
I need to implement these cases:
($VERBOSE = 0 && $LOG = 0) => ONLY ERROR output (STDERR to console && STDOUT to /dev/null)
($VERBOSE = 1... (5 Replies)
