need shell script to backup HPUX SAS913 contents and metadata

[Jan Shu]

Hi All,

I have a production SAS9.1.3 DI server running on a HPUX 11.23 Itanium server. I am looking for a shell script to do the following steps automatically in a cron job at 10PM EDT daily. Can you please help?

1. stop 3 SAS processes
/sas/MetadataServer/MetadataServer.sh stop &
/sas/ObjectSpawner/ObjectSpawner.sh stop &
/sas/ConnectServer/ConnectServer.sh stop &

2. tar 5 sas file systems (only 10GB total) to /sasbackup/bak/ directory

3. start 3 SAS processes
/sas/MetadataServer/MetadataServer.sh start &
/sas/ObjectSpawner/ObjectSpawner.sh start &
/sas/ConnectServer/ConnectServer.sh start &

Thank you.

Best Regards,
Jan Shu

Hi Jan,

Lets say your script name is bakup_daily.ksh
in /usr/local/bin
This script has your steps 1 thru 3

Add this to Cron.
crontab -e
00 22 * * * /usr/local/bin/bakup_daily.sh >> /usr/local/bin/bakup_daily.log 2>&1

When you start processes in backgrond, it is a very good idea to issue a wait so that execution in the parent shell does not continue until all the background processes complete:

e.g.

/sas/MetadataServer/MetadataServer.sh stop &
/sas/ObjectSpawner/ObjectSpawner.sh stop &
/sas/ConnectServer/ConnectServer.sh stop &
wait
tar ...

While issueing all the stops in the background is a good idea so that the 3 can run simultaneously, you normally want the files stable when the tar begins --- that's what the wait does.
