bpend notify for DSU

This issue has been solved. See solution.

Hi All,


Master server : Netbackup 7.1 + Solaris 10, Media server Netbackup 7.1 + Solaris 10

Media server has DSU which backs up all windows client (Disk size is 3.5 TB) ,

Our backup window is 6 Pm to 8 Am next day

We have a DSSU job which duplicates images from Disk to tape (Morning 10 AM)

i have created a script which checks all Disk images , where ever it finds number of copies = 2 , it will delete Primary copy in disk .

I have few of questions

1) Can we have Different retention levels on disk and tape(Can it be done through DSU)?

2) There is a cron that runs from master server at 10 AM , it runs duplication jobs , I want to create bpend.notify script which calls delete script right after Duplication job is over, i want to know if that is possible

Using Disk staging with Basic Disk(DSSU), you can not set different retention level for disk and tape.

bpend_notify is only called at the end of backup jobs - not duplication jobs. Why don't you add the call of your delete script at the end of your duplication script called by cron?

Just wondering why not to use SLP ?

There is no such duplication script set through cron , basically i am just using bpbackup command in cron everyday at 10 Am

00 10 * * * /usr/openv/netbackup/bin/bpbackup -i -p __DSSU_POLICY_disk_stu

I was wondering if i can configure bpend.notify script like where i will call delete script

 The reason i am not using SLP is .,This is basic disk and i believe if you dont have enterprise client license you cannot move images from disk to tape

Why not try Yasuhisas suggestion:

change your cron such that it's not calling the backup/duplication directly, but calling a script that runs the backup/duplication - your delete script can then be added to that same script to run once the backup completes.

A couple of things here ....

1. You cannot have a different retention on disk than on tape using DSSU. This can only be done using SLPs which require that you use Advanced / Enterprise Disk (licensed option) - this does have an expire after duplication option built in.

2. Can I ask why on earth you are doing what you are doing? DSSU is self capacity managed and will not run out of space .. it the disk has filled up then it will clear down space automatically as long as the images have been duplicated to tape so it is self managing.

The beauty of using disk as the primary backup target is that it is both fast and it is "always there" so that when someone needs a restore you don't have to go recalling tapes.

What you are doing takes this advantage away so I was curious to know why this was the case.

Hope this helps

Agreed.  It sounds like you are trying to perform functionality that is better done by NetBackup.  SLP would be much better way to go.

Yes, Mark I guess Point 2 you have made has very much cleared issues, i did not want to fill up DSU more than 80% so i have changed my water mark values accordingly

SLP is defineatly ideal option but We do not have Enterprise disk option license available with us
