Pre/Post script commands for backup

You could write a script on the client that is called via cron, freezes this and once actually frozen call a bpbackup to do a user directed backup.

Otherwise you have bpstart and bpend notify scripts to call the freeze.

https://www.veritas.com/support/en_US/article.TECH162973

Only downside would be that there is no gaurentee of it being frozen by the time the backup hits it which is why I would suggest a script that ensures it before calling bpbackup.

You could defnitely then use the end notify to unfreeze.

Thanks mnolan for your response,

I have not written a script before so not sure  how to call it. I will take a look at the tech note see if it helps.

The "how to use bpstart and bpend notify scripts"  tech note is okay. However I need to find more examples of how to call the freeze or a Data store.

Like parameters/statements more along the lines of

To freeze the Data Store file at start of backup:          

/usr/pareet/bin/ freeze +<number of seconds>

Example - to freeze for 1 hour:

/usr/pareete/bin/ freeze + 60 minutes

To unfreeze (immediately) the Data Store once backup is done - I guess the name should of the Data Store should be placed in a specific place.

I'm not sure freeze is the correct terminolgy for the script would stop be better?

Thanks

Hi, If I wanted to freeze a data base or file where would I put it in the script below?

1 = pheonix
%2 = pheonix1.my company.com
%3 = Pheonix1.schedule
%4 = one of the following: FULL, INCR, 
%5 = STATUS, always 0
%6 = RESULT_FILE\netbackup\bin\goodies\bpend_notify.bat

-thanks

Any 'notify' scripts need to be moved into the <install path>netbackup\bin (win) or /usr/openv/netbackup/bin (unix) for them to be found and executed.

Note: The return status from the script is checked. Any non-zero status returned from your script will result in a failed job.

Hi Mark thanks,

Freeze needs to be done prior to the backup to ensure it does not get corrupted (the  filesystem is thousands and thousands of little files that make up the larger files). 

content store (TSSTORE)

Apparently    bpstart and bpend notify scripts can call a  "freeze" not sure exactly how that would be written any suggestion, comments?  any examples or other links ?

Thanks

If you can set up ssh with key exchange for root on both systems so you don't need a password, You can execute remote commands via ssh.

Something like this in your bpstart script:

ssh root@pheonix '/path_to_exec/freeze -60 minutes'

And in the bpend script:

ssh root@pheonix '/path_to_exec/unfreeze'

Use single quotes.

Thanks Dave, That helps

I have never set up ssh with key exhange, I will try,

 bpstart script:

ssh root@pheonix '/path_to_exec/freeze -60 minutes'

The "/path_to_exec would be the path on pheonix of the tsstore or the /usr/openv/netbackup/bin?

 = pheonix
%2 = pheonix1.my company.com
%3 = Pheonix1.schedule
%4 = one of the following: FULL, INCR, 
%5 = STATUS, always 0
%6 = RESULT_FILE\netbackup\bin\goodies\bpend_notify.bat

Thanks

Hi nbustarter380,

Can I ask whether you need bpstart_notify and bpend_notify scripts for Solaris, as hinted/indicated by your opening post?  Or whether you need the two scripts for Windows, as hinted/indicted by your subsequent posts which refer to DOS/cmd/batch variables (and results file based) ?

Hi Sdo,

Sure you can ask I need all the help I can get. I need bpstart_notify and bpend_notify scripts (or something ssh with key exchange? as Dave suggested for a Solaris Client using 7.6.0.3 (sorry for any confusion). Its to freeze a Data Store at the start of a backup.

Similar to the one below that apparently was put in on a similar (solaris client) when we were using a different backup solution.

To freeze the Data Store at start of backup:          

/usr/iw-home/bin/ iwfreeze +<number of seconds>

Example - to freeze for 2 hours:

/usr/iw-home/bin/ iwfreeze +7200

To unfreeze (immediately) the Data Store once backup is done - if before the specified freeze time has been reached:

/usr/iw-home/bin/ iwfreeze --

The freeze needs to be prior to backup and unfreeze afterwards.

Again I have actually never done a script before so any help is appreciate.

Thanks again for your replies.
