Hi all

I would like comments on this solution to run fortnight daily backup
using 10 tapes.
and on the last Friday of the month to run a Monthly backup for
archiving purposes and pull out of System until the following year.

I have hacked up two scripts from the this list.

First of all here is mt cronjob::
I need to know what tape is in the current tape drive be it the usual
daily tape
and of course if it happened to be the last friday in the month or say a
monday I will to put the next daily tape or on the thursday before the
last friday of the month backup to be ready to put the next monthly tape
in.

I am aware the amdump send a report on failures or successful backups
but
if a daily schedule is run and it's going to be a last friday and I put
in daily tape 
does the script ignore the daily tape and amdump monthly report So and
thus I can say on monday put in the monthly tape and run amflush.

Cheers


# Check which Amanda tape if Daily or Monthly.
0 14 * *  1-5 /usr/sbin/check_amanda_tape.sh

45 19 * * 1-5 /usr/sbin/last_friday_month.sh

Here is the Last Friday In Month script (last_friday_month.sh).
#!/bin/sh
# Script last_friday_month.sh
# chmod 755
# Amdump - Last friday of the month script to check prior to running
usual daily tape
# or the monthly tape backup.
# Ensure the in the amamda.conf file the within the dumptype
# paramter for root-tar that record is set to no 
# example - record no This is to stop Monthly ruining the Daily
Schedule.
# Summarisation of the script
# cal - prints month calendar
# awk - selects friday column date
# tail - last date
# -eq -  date compared last date with todays date.

if [ `cal | awk 'NF >= 6 {print $6}' | tail -1` -eq `date +%d` ]
then  su -c "/usr/sbin/amdump MonthlySet"
else  su -c "/usr/sbin/amdump DailySet1"

fi

Here is the Check which tape (check_amanda_tape.sh) is in the drive
prior to any amdumps running at 19:45

#!/bin/sh
# Script check_amanda_tape.sh
# chmod 755
# Amcheck - Last friday of the month script to check prior to running
usual daily tape
# or the monthly tape backup.
# Ensure the in the amamda.conf file the within the dumptype
# paramter for root-tar that record is set to no
# example - record no This is to stop Monthly ruining the Daily
Schedule.
# Summarisation of the script
# cal - prints month calendar
# awk - selects friday column date
# tail - last date
# -eq -  date compared last date with todays date.

if [ `cal | awk 'NF >= 6 {print $6}' | tail -1` -eq `date +%d` ]
then  su -c "/usr/sbin/amcheck MonthlySet"
else  su -c "/usr/sbin/amcheck DailySet1"

fi
