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.

BACKUP_DELVOLSET(8)					       AFS Command Reference					       BACKUP_DELVOLSET(8)

NAME
       backup_delvolset - Deletes one or more volume sets from the Backup Database

SYNOPSIS
       backup delvolset -name <volume set name>+ [-localauth]
	   [-cell <cell name>] [-help]

       backup delvols -n <volume set name>+ [-l]
	   [-c <cell name>] [-h]

DESCRIPTION
       The backup delvolset command deletes each volume set named by the -name argument, and the volume entries each contains, from the Backup
       Database. The backup listvolsets command lists the volume sets (and their volume entries) currently defined in the Backup Database.

CAUTIONS
       Deleting a temporary volume set is possible only within the interactive session in which it was created. Exiting the interactive session
       also destroys the temporary volume set automatically.

OPTIONS
       -name <volume set name>+
	   Names each volume set to delete.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
	   the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
	   details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES
       The following command deletes the volume set called user and all volume entries in it:

	  % backup delvolset user

PRIVILEGE REQUIRED
       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
