EMC NetWorker Review
Backup software solution which supports majority of IT platforms (Windows, UNIX, Oracle, SQL, Lotus, VMware etc.)


Valuable Features

Backup jobs can be scheduled and automated

Monitoring of backups and configuration tasks are centralized

Compatibility of the solution covers large OS/DataBases/Applications

Improvements to My Organization

In a large enterprise DataCenter there is traditionally a lot of applications/databases which are owned by different administrators.

Without a centralized backup solution, each application/DB owner has to ensure its backup separately and if a problem occurs, he has to execute recovery tasks. In these conditions, the application rower has to make some extra jobs : backup scripting, verifying backups have finished successfully, recovery jobs... This does impact his efficiency and the global enterprise efficiency.

If a centralized backup solution like Networker is deployed, the backup/recovery tasks will be on the responsibility of only one resource which is the backup administrator. This does directly involve that each application/DB owner can spend more time on his real job: optimizing the platform that he owns.

Room for Improvement

With Networker 8.0 I had an issue related to VMware VADP backups.
An Image level backup of a RHEL VM finished successfully, but when I tried to restore it the transfer speed was very low, and the restore operation took 20 hours to restore 17 GB which represents 50% of total VM size. I was then obliged to abort the restore operation because there was backup jobs planned and Networker was deployed with only one tape drive in this case (the tape drive can't write backups and perform restores simultaneously).

I contacted the support team to analyze this performance issue. They said that this happened because it was a Linux machine backed up with Windows Vcenter Proxy. For me this is not acceptable... I hope this will be resolved in the 8.2 version of Networker, because restore speed is important (RTO)

Use of Solution

Deployment Issues

Deployment tasks are not really hard. Networker is well documented.

Customer Service and Technical Support

7/10

Initial Setup

Initial setup was complex because I had to integrate Exchange Server and I had no knowledge on how it works.

I asked to the Exchange administrator to assist me on the deployment and together we setup up the Exchange backup job.

Other Solutions Considered

IBM TSM; HP data protector; Symantec Netbackup/Backupexec are main competitor to Networker.

I remember a customer asked me to advise him between deploying Networker or TSM. The customer wanted to integrate a Data Domain device to his backup solution. I advised him to use Networker because TSM is not compatible with DDBoost protocol which improves DataDomain performance: Deploying TSM in this case was a limitation!

Disclosure: My company has a business relationship with this vendor other than being a customer: We are an EMC partner
