There is a new technote entitled "Best Practices for using Storage Lifecycle Policies in NetBackup 6.5.3 and 6.5.4". This essential document, authored by engineering, support and product management, documents best practices, and is based on consolidated information obtained from real world experiences.

If you are planning to implements SLPs or already have, becoming familiar with the suggestions in the documents will allow you to both tune your systems for your workload and gain insight into the current state of your lifecycles.

If you aren't familiar with Storage Lifecycle Policies, also known as SLP's, they are one of the more innovative approaches I've seen in the last few years for to allow a user to describe a life cycle for a backup data, without creating complex nests of overlapping schedules. If you aren't familiar with SLPs you can read more in the white paper entitled,...

If the size of the heap data segment is limited then for large process we may have a core dump because of the way the memory management is implemented in AIX.

Following are the quick solution to try out :-

1. ulimit -d unlimited ------ should allow larger process.
2. Increase the LDR_CNTRL=MAXDATA setting at the AIX level prior to executing the command.
export LDR_CNTRL=MAXDATA=0x20000000 ( Default on AIX is 0x10000000)
To make the setting permanent, place the LDR_CNTRL=MAXDATA=0x20000000 to the end of the/etc/environment file.
All must be set in the environment of the netbackup processes at startup.
3. NBU since 6.0.MP7 takes care of such issues. Because later the way the binaries were built was changed to take into consideration such scenarios. Making the changes in the /etc/environment will make the changes for the entire system.

Technical Explaination:-

On AIX, the 32-bit address space (= 232 or 4 GB) is divided into...

Growth is a problem lots of companies would like to be dealing with right now. But it isn’t always easy to manage growth, especially growing your IT infrastructure to keep up with a fast-growing business.

This was a problem facing ENGlobal, an engineering firm that provides services to the energy sector. ENGlobal has experienced tremendous growth in recent years, both organically and through acquisitions.  As a result of this growth, the company ENGlobal had outsourced its backup operations to couldn’t keep up, causing backup costs to increase by 50 percent.

ENGlobal made the determination that could cut costs and be better off financially in the long run if they were to bring data protection back in house. The company turned to NetBackup to solve its backup needs. Over the life of the project,  ENGlobal expects...

How deduplication can contribute to the restore process….

A couple of days back, whilegiving a PureDisk lecture, I got into an interesting discussion about howdeduplication technologies pop up at different levels: deduplication at the source, at the target,at a gateway level, or built into the application. You name it; they are allavailable and focused on incredible numbers pushed by dedup enthusiasts.

In the case of the backupsolutions, the focus seems primarily on dedup savings during the backupprocess, where higher deduplication rates can deliver higher backupthroughputs, reduce backup time, and support much longer retention on disk. Allare correct and very efficient, don't get me wrong, as I'm one of thoseenthusiasts, but what about the restore process? That is where thediscussion touched an interesting subject...

Can deduplication be used toimprove the restore speed? The answer is Yes!

Take, for example, the remoteoffice...
