Re: Storage Pool Backup Issue

Joni,

For each of your primary disk storage pools you will need a script that:
- Backup stg disk -> copy maxproc=#drives wait=yes;
- Backup stg tape -> copy maxproc=X wait=yes;
- upd stg disk Hi=X lo=y. # start migration of that stg pool.

This way you don't have the rest of your stgpool maintenance waiting for
the most used stgpool job to finish.

At the end of the script you can define a admin schedule which fires off
a script that checks if the migration has ended and if so reset your
diskpools hi and lo parm. This admin schedule in turn can fire off a
admin schedule which runs a script to check of any of the storage pool
jobs is still running and if not do a db back-up en pre.



Regards,

Karel

True - so what Joni needs is a script that uses 6 "streams" to backup
the diskpools, then throttles back to 3 "streams" to do the tape to tape
backup.

With 6 scripts , you could end up with up to 6 processes each backing up
"onsite tape to offsite tape"..........requiring 12 drives!, you would
also end up with several offsite tapes.

Joni,

Sounds to me like you need 6 scripts that all use wait=yes, and you will
have to balance which pools get backed up in each script.

Hello Everyone!

I have an issue of drive shortage and I would like to cascade my backup
jobs of my storage pools.  I know that you first want to make the disk
to offsite tape copy and then the onsite tape to offsite tape copy for
each storage pool.  My question is, how do I combine all 14 jobs in a
cascading order so that they are only using a maximum of 6 drives at a
time?  I thought about putting them all within a script and running them
with wait=yes but I don't think that will give me exactly what I want to
do.  If anyone has any suggestions I would appreciate the input!
Thanks!
