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.

virecover

VIRECOVER(8)						    BSD System Manager's Manual 					      VIRECOVER(8)

NAME

     virecover -- report recovered vi edit sessions

SYNOPSIS

     /usr/libexec/virecover

DESCRIPTION

     The virecover utility sends emails to users who have vi(1) recovery files.

     This email gives the name of the file that was saved for recovery and instructions for recovering most, if not all, of the changes to the
     file.  This is done by using the -r option with vi(1).  See the -r option in vi(1) for details.

     If the backup files have the execute bit set or are zero length, then they have not been modified, so virecover deletes them to clean up.
     virecover also removes recovery files that are corrupted, zero length, or do not have a corresponding backup file.

     virecover is normally run automatically at boot time using /etc/rc.d/virecover.

FILES

     /var/tmp/vi.recover/recover.*  vi(1) recovery files
     /var/tmp/vi.recover/vi.*	    vi(1) editor backup files

SEE ALSO

     vi(1), rc.conf(5)

HISTORY

     This script, previously known as recover.script, is from nvi and was added to NetBSD in 1996.  It was renamed in 2001.
