Reviews (1-5 of 5)
- I don't think this product does anything well. It shines only because of the Data Domain integration.
- The support teams is excellent, which is good, because you'll need them. Frequently.
- The project implementation team is also competent and professional but their hands were often tied due to poor direction from the sales team.
- The GUI is horrible. Giant windows that don't size properly, confusing terminology, multiple clicks to get things done, it's just a disorganized mess. I can't put this in front of my junior techs because it requires some background in DR software to fully comprehend, and even then it's not easy. It feels very much like this was tacked on to a command-line based product as an afterthought.
- Better management features. It's difficult to integrate with Active Directory, for one. You'll need a Dell EMC tech to help you. Items can't be renamed and have to be recreated. Options are buried in multiple GUI tabs and often are just command line strings in a free-text field. Diagnosing failed jobs and workflows is cumbersome and the errors are often cryptic without some experience. Design it well and pray for uptime, because you need this to work when disaster requires it to.
- Poor reporting features for an enterprise class product. You can't schedule any type of simple summary (an audit requirement for us) in the base product. To do this requires the additional cost of Data Protection Advisor, which is also horribly designed and impossible to get working quickly.
- Post-sales contact is non-existent. We've been through a few reps and the project team dropped us at one point with a half-finished implementation when the original sales guy moved on. We only got the the promised product implementation by telling Dell that we weren't paying the bill until they delivered what they promised and were contractually obligated to.
- Networker has proven to be really reliable in restores. If it says it was backed up successfully we have never had a restore failure which is great. Some backup software fails at this most important task, but Networker has been reliable.
- Networker is efficient on system resources. It takes a lot of backing up in order to put our Networker (VM) under any meaningful load. We back up about 60 VMs at a time while backing up other resources (such as the NAS) and it is a breeze for the system.
- Networker is flexible. It takes a little bit to understand how everything is linked together in the interface, but you can customize just about anything about your backup jobs from speeds, threads, backend targets, schedules, and level all very easily.
- We backup to a data domain, which I think does most of the magic, but it is a very compressed/deduped/small backup size relative to the whole sum of the data which is great. Essentially it is very efficient on the storage side, at least when coupled with a data domain.
- Networker terminology is awful. My favorite example is that many required-to-function configuration changes need to occur with the advanced configuration enabled. To make this worse, the 'advanced configuration' I am speaking of is actually called 'Debug Mode'. That's right, you must use debug mode in order to have a functional administrator interface.
- Errors are common and to resolve you often must go to support. You really need to be an expert to fix many errors, the steps usually involve being really knowledgeable in the CLI tools, which I am getting good at, but the public documentation is seriously lacking for troubleshooting these issues. That said, support (through emc) is really good at handling the common issues, friendly, generally knowledgeable, and quick to respond.
- It runs on Java, and sometimes I need to clear java cache to fix interface bugs. Generally this isn't an issue, but it is additional software you must worry about.
- Networker has a UI and set that is relatively easy to use. It has a policy-based backup system that is straightforward as far as configuration.
- Networker has fairly robust reporting on current save sets and easily exportable pdfs and spreadsheets of statistics and metrics
- Networker has a monitoring dialogue which allows you to find out quickly what has succeeded or failed.
- Networker's customer service could use a bit of improvement. While some problems are handled quickly, complex issues sometimes have limited responses with difficulty to escalate up the chain.
- Networker prior to version 9 is using outdated policy configuration which tends to make some backup windows and obligations awkward.
- Networker needs a bit better method for accommodating plugin integration with other applications, and better documentation on implementation of those modules.
- When used with a Data Domain appliance, using either DDBOOST or a VTL, it is quick and does a wonderful job of deduplication. We have 2.3 PB stored on a 140 TB DD 4500. While this is expensive storage, the cost for 2+ PB would be even higher.
- It does a good job of brick-level backups of Exchange mailboxes, and does so in very good time. A few hours backs up our entire organizations mailbox stores in a way that provides object level restore.
- Used in combination with DPA (Data Protection Advisor), it has a very good reporting capability. DPA, however, requires more than just surface knowledge in order to get really good reports, and the DDOS changes can wreck havoc with customized reports.
- NetWorker has a number of glaring flaws. For starters, it does not have any built-in vaulting capability. I simply cannot believe that EMC thinks nobody takes tapes out of their libraries. Their response to our inquiry about it? "We can write a program for you that will cost x-thousands of dollars, or you can develop one yourself." We wrote our own customized program to vault tapes.
- NetWorker does not posses any Disaster Recovery reporting capability. Again, we had to custom code reporting for this so that tape librarians would know what tapes to recall from offsite storage for entire groups of servers. During a crisis there isn't time to be doing that on a one at a time basis for hundred or thousands of servers.
- NetWorker is extremely sensitive to DNS changes, and appears to cache DNS data in hidden locations. We have servers being reported by NetWorker as not connected when they were decommissioned years ago, removed from AD and DNS, yet we still cannot get NetWorker to stop complaining about them.
- NetWorker does not play well at all with multi-homed clients (more than one network interface). In environments where it is not conducive to backup servers of a production network, it becomes crucial to do so over a dedicated or secondary LAN. This causes huge issues with NetWorker.
- If a group contains a number of clients, and one of those gets hung up during a backup, the entire group fails. That is a very wasteful approach for both time and infrastructure resources. Instead, it should fail the one client and allow the remainder in the group to complete successfully. It should also allow the group run to be canceled and still keep the good clients backups rather than registering the entire group as failed.
- There is no way in NetWorker to identify specific file/directories that fail to backup successfully. It will report on savesets, but I need to know that file abc.dat or directory F:\Program Data\ failed and why. It does me no good to get a warning that the saveset for the F drive failed. What failed and why? It may have been a critical problem, or it may have been of no importance.
- We endured three years of NetWorker experiencing problems, enduring a grueling process of trying to get knowledgeable and rapid support -- sometimes taking days and weeks, and only after getting really pushy with support managers -- only to have the problems return over and over. For example, it has been a regular issue for the peer information to get clobbered for no apparent reason. The result is the backup fails for that client, and then I have to go in and remove the peer information on the NetWorker Server, all affected Storage Nodes, and the client. I can now run nsradmin -p nsrexec and then the print and delete statements for nsr peer information in my sleep.
It's a single application to manage all different backup datasets
- One application to do all
- Multiple device integration and support, like DD, Tape, AFTD etc
- Easy-to-manage portal (Networker Management Console)
- Set-it, forget-it setup
- Price sometimes tends to be higher for mid-size companies
- Support sometimes a little delayed
- DR recovery can be a little lengthy & time consuming
Not too good with Oracle DB backup
DR recovery process is not too straight forward, makes it tough to run DR recovery test
