Re: ESXi 6.7 creating a snapshot taking a long tim...

DrorAmbar · ‎09-20-2022

Hello all,

I am having an issue with snapshots on one of my servers are taking a very long time to create.

The server is a PowerEdge R540, 10 CPUs x Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz, 64 GB RAM.

I am taking a snapshot of a Windows 2016 guest and it's taking about two hours to complete.

Same setup on three other hosts not as robust as this one took a few minutes with the "Snapshot the virtual machine's memory" option selected.

I read a post suggesting to remove to have that option removed. Is there any reason to be concerned performing the process that way?

So I'm not sure what are the possible reasons causing this to take place to begin with.

Any guidance will be appreciated in advance!

Hey @DrorAmbar ,

Do you have any other snapshots for that VM?

Hi ptarnawski,

No, that was the very first snapshot

As you mentioned, you can uncheck the memory state, the only difference is that without memory state your VM, once restored from the snapshot will be powered off and you need to power it on manually.

Worth to try.

Thank you @ptarnawski for the explanation

Making sure that I understand you correctly: If I take a snapshot unchecking the memory state, then perform "delete all" - will the VM be turned off when it's done or that is not even a concern in this case?

DrorAmbar · ‎09-23-2022

Hi @RajeevVCP4 no I haven't tried that.

I am not familiar with that option, can you please provide more information about it or any references to how it's done?

I am assuming that I will have to enable SSH for that.

@DrorAmbar

Try use PowerCLI command to take snapshot of the affected VM.

Try this out.

Get-VM -Name VMNameHere | New-Snapshot -Name SnapshotName -Description SnapshotDescription

You need connect to the vCenter to run the above command

Regards

Sam

Hey @DrorAmbar ,

If you delete a snapshot, nothing will happen, VM is ON. If you restore from snapshot, VM will be powered off.
