There's not much documentation out there on what it is or does -- try disabling it to see if there are any untoward effects.  There probably won't be -- most of the pre-loaded services are more trouble than they're worth.

Did that and nothing bad has happened yet. Actually stopped 7 different Dell services and everything seems okay. Just like what happens on your phone, except I know how to disable them on my laptop. Being honest, if no one knows what it does it can't be very useful. Thanks

Dell PowerProtect Data Manager builds on top of project Velero to provide a data protection solution that enables application-consistent backups and restores and that is always available for Kubernetes in on-premises and in-cloud workloads, VMware hybrid cloud environments and Tanzu modern applications

I don't think the software in question on an Inspiron notebook has anything to do with an enterprise backup software utility.

I use Norton 360 for system backup and actually don't know what "application-consistent backups and restores" are. So I really don't think I need it.

@Jack63SS Sorry, but I don't understand how this can be marked as the "Accepted Solution" when it doesn't really answer the question.

We're looking to cull unnecessary Services from our Vostro 5620, and are trying to research before going scorched-earth. Dell Data Manager is unfortunately only one example of many.

IMO, it's unacceptable that Dell throws RAM-consuming (often superfluous, buggy) Services on the device without even providing an explanation of what they are, how they're used, or implications of stopping the Service. "Just get rid of it and see what happens" can be problematic, as related issues may not surface for some time, and the connection to the stopped service may not be apparent.

I ABSOLUTELY AGREE with what you said about unnecessary Services. And they all do it; WINDOWS, Dell, Toshiba, Samsung, Amazon on PCs, tablets, phones, everything. When I got my new Dell laptop I spent 2 days trying to figure out what I needed and what I didn't. And 50% are NOT documented at all as to what they do. Problem is some of the Services are actually important and necessary for your system to run. So what these companies do is add in everything so they don't have to document Services for different cases, like home vs residential. It's all in the money.

I actually have some Services set to Manual or Disabled on my system and run a script to start them when I need them. Kind of extreme, but it works. 

And I marked my question Solved because what I really wanted to know was if I could safely remove it. Guess I should have asked it that way. 

IMO, Dell is out of control. Post OOBE, there were over 400 MB of RAM being consumed by these services around the clock. All this without decent documentation!

I've worn my fingers to nubs Googling, but haven't gleaned much definitively. If anyone has any insight, please chime in - it will be appreciated.

In the end, we plan to retain Dell Update, SmartByte, and if necessary, Waves. Not sure about anything else.

We already deleted apps & services related to:

• Dell Digital Delivery (no software purchased from Dell, so why is this installed / consuming RAM 24 x 7?!?)
• MyDell: This is just a wrapper for general device 'how-to' links, peripherals sales, Dell Cinema Color, Dell Power Manager / UEFI settings, Waves Maxx, SmartByte, and SupportAssist,. Waves and SmartByte also consume RAM, but we intend to keep them for now (we tried uninstalling Waves in a previous incarnation, and ran into issues).
• Dell Fusion: Not functional without MyDell, I think.
• Dell Customer Connect: If applicable, Dell will install a temporary exe to accomplish the same thing.

On deck is the uninstall of SupportAssist. This will hopefully (!?!) get rid of the following:

• DCFWinService
       Dell SupportAssist Remediation

• DDVDataCollector
       Dell Data Vault Collector

• Dell Data Manager

• Dell Data Vault Data Collector Service API
       Dell Data Vault Service API

• Dell Data Vault Rules Processor
       Dell Data Vault Processor

• Dell Diagnostics 

• Dell Instrumentation

• Dell User Session Agent (?)

• Dell.DCF.UA.Bradbury.API.SubAgent.exe

• Dell.TechHub
       Dell TechHub
  
  
• ServiceShell (?)
       Dell Client Management Service
• SupportAssistAgent.exe
       Dell SupportAssist

The other thing to note as that when going through Settings > Apps, Dell's uninstall routines are sloppy, leaving, residue behind. We've been using Revo Pro, which does a much better job of deleting remnant app folders and pruning the Registry. Copious restore points and system images in between, of course.

Update to my post above re SupportAssist: After months (!) of back and forth with ProSupport, I've learned: 

0. The ServiceShell Service is required for Dell Update, and therefore shouldn't be stopped if you want to use that app.

1.  Information shown on https://www.dell.com/support/ is wrong from Day 1!  Dell liberally swaps components (e.g., SSD) based upon availability and/or their cost, yet the portal - even when referencing a specific Service Tag - only reflects the "standard" build, and is NOT UPDATED to reflect actual components put into customer's devices. Never mind the packing slip isn't specific about what SSD is actually used in the device (you might glean some info by clicking on the "view product specs" link) so most customers will never know the portal is recommending inapplicable updates for their devices. IMO, this so easily addressed with a bit of process, not doing so is inexcusable, and shows Dell really doesn't have any regard for its customers.

2. Dell Update is in the process of being deprecated in favor of SupportAssist, and may not be kept (as) current. Dell Command Update is likewise not being updated to support many devices (e.g., XPS8950, Vostro5620) still being sold today, so this isn't a viable option.

In light of the above, rather than uninstall SupportAssist, I built a Powershell script, likely similar to what @Jack63SS mentioned above, which a) stops services, and sets those services to manual / disabled, so they won't re-start on every reboot, and b) kills several left-over processes. The same script can also restart those services and processes based upon an input, if desired.

My solution is to run the script monthly to enable SupportAssist, run SupportAssist, then run the script again to disable it. I'm looking into incorporating the script into Task Scheduler, but that's TBD.

@Jack63SS I'm far from being proficient with Powershell, but would love to compare notes if you're interested.

Come on Dell.  Why wont you tell what Dell Data Manager does. And why it eats up so many cycles on my Inspiron running Windows 10.  What are you hiding.  Or have you outsourced all the people who had any idea what this was?

@AdrianG001​ That sounds like it came right out of a sales brochure.  But what does it mean everyday?

@AdrianG001​ Is there an English translation of this message?

I also have Dell Data Manager and a lot of other Dell process running constantly (similar to the list 'And Ye Shall Find gave above) and using up a substantial part of my memory.  I can't really unpick the conversation above to work out whether I should disable these processes, how to do it safely and how to reverse it if everything goes wrong.  I am going to need to update my computer fairly soon but would be very nervous about buying Dell if the platform is going to contain a heap of undocumented and uncontrollable processes. 

For anyone still experiencing this, can you let me know the version of SupportAssist installed on the system?
