vm copy form remote site to dc via ipsec vpn

[TDG]

Hi this job often fails on some VM's

Product: Veeam Backup & Replication
Additional Details: 18/06/2024 05:01:58 :: Processing dc01 Error: NFC server [dc-esx1] is busy.
Delivery of a FILE_PUT message has failed. Processed file: [[net app ds] __MKS-VM-COPY/dc01_vm-80_/dc05-flat.vmdk]. Size of the processed data: [51196698624]. Size of the file: [53687091200].
Unable to receive file.
Shared memory connection was closed.

B/W at source is 1gbps
B/W at destination is 1gbps
The route is: source >> HQ vis ipsec vpn >> then to DC via 1gbps p2p line
At destination we have 2 ESX hosts dc-esx1 and dc-esx2 (With a 16gbps FC NetApp SAN for VMFS) but 1gbps networking

Any idea pls

I'm on the latest Veeam but my licences doesn't support replication to remote ESX that's why I' using Veeam VM copy
Just to keep a copy of important VM in DC for BR/DC purposes
(I'm already backing up to Wasabi and to local which works fine)

I do have replication licences in our HQ Veeam and it replicates to the same DC ESX hosts without any issues but it uses a direct p2p line this indicates the IPsec issues from remote site to HQ ? Maybe ?

Or maybe I should do a direct IPsec to DC from remote site and see ?

Or do differently ? Say Veeam ZIP and copy to DC ? Or a backup copy ?

Hi TDG,

The error is indicating that the host was too busy with other tasks -- the copy will use NFC from Vmware to move the data, but depending on your environment, sometimes the NFC server is busy with priority tasks that need NFC and the other sessions get interrupted.

I think Support has some registry values that can adjust the retries and timeouts, so please open a Support Case and include logs from the Veeam Server after reproducing the issue. Please note the date/time of the test and the name of the VM that had the failed copy, as this will help Support narrow down on the issue and confirm the behavior. Please share the case number once created.

Similarly, would Quick Migration or just an Instant Recovery/Entire VM restore to the new host work instead of VM Copy?

Thanks David yes I have already opened a case but your reply is far much better answer

Also I can deploy more NFC servers if nodded ?

Could you explain a bit more re; this ?
Similarly, would Quick Migration or just an Instant Recovery/Entire VM restore to the new host work instead of VM Copy

All I need is to get a copy of the remote site VM to our DC say 2 jobs one runs every 4 hour (Working hours) and another daily in the night simple as that & We are planning to upgrade the VMW estate in our DC and get a 10gbps connectivity

You're welcome for the answer so far; can you share your case number for us here please as is requested when creating a topic?

As for the suggestions, I'm not quite sure on your needs (if it's a repeating copy that must be done or just a one-off migration), but we have the Quick Migration feature:

https://helpcenter.veeam.com/docs/backu ... ml?ver=120

Similarly, if you have backups of the machine, you can simply do an Instant Recovery or Entire VM Restore to the target host instead of the VM copy. This would read the data from the backups of the machine instead of putting workload on the source host, but maybe you can elaborate on your plan a bit more.

Ah ok Case #07306738

I don't have replication licences so I can't do this
Like I said form the source Veeam I do have Wasabi & local backup which is already setup and running nicely
So I have all the VM's in a local reposits and all the VM to Wasabi S3 so 2 backups

Need a 3rd so we keep a copy of some important VM's (5 in total) form our remote location to our DC on a regular basis i.e. a regular job (Not one off)

[david.domask]

Thanks for sharing the case number.

As for your strategy here, just to confirm, we talk about a copy of the production VM correct? Not a copy of the backups of the VM?

Quick Migration doesn't require any VMware licensing, but since you're wanting additional copies, I guess that's not the right answer here.

Why not a Veeam Replica job? That's exactly what it's built for, can be scheduled like any other job, and should help here.

Yes copy of some not all production VM
(I can go with backup copy as well if it works better)

Re: Veeam Replica to remote hosts good question - I don't have the licences in the Veeam version I'm running on the remote site
Veeam Data Platform Essentials 25 Instances
Smaller remote site

(I'm already using Veeam replicas in our HQ to DC because I have licences - Veeam Data Platform Foundation Enterprise Plus with xx Sockets) Bigger site

[david.domask]

Got it, let's see what Support turns up then from the case. I see there was a remote session it looks today and indeed they advised some registry values that may help.

As for Replicas, understood on the licensing, I would still consider periodic restores of the machine but VM Copy works too, it's largely a matter of preference and restore option would naturally be a bit out of date compared to the production VM, but this will be true for all available options right now.

Thanks we did 2 regedit changes and I have rebooted the box & will try VM copy

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
NfcWritingRetryCount - 20
NfcWritingRetryTimeoutMs -1000

It's looks like VM copy is not very popular

Also I'm in the middle of routing ipsec vpn direct so this may also help

Will see how it goes & if not I will have convince my boss to upgrade the licences so I can have replica to a remote site

Cheers for your help & Keep up the good work

[TDG]

Hi just an update

Just noticed on the remote site we have Veeam Data Platform Essentials 25 Instances which supports remote relocation and it works better than legacy VM copy so issue sorted

Happy Days

[david.domask]

Glad to hear that it worked out and you had licensing after all Indeed, I think you'll be happier with replicas and it will be a lot less to manage, plus you get a lot of flexibility and features from Replicas as well (consider SureReplica in your future as well as all the features that opens up, File Level Restores from replica, failover and failback, failover plans, there's a bit that the replica path opens up for you )
