Change Repository IP Address

[augsysad]

Hi,

I am having some trouble changing the IP Address of a Windows Server Repository. The box in question only hosts the Repository role and is moving to a different subnet, but there doesn't seem to be an option to change the IP address of it. I have a decent amount of data I want to avoid recopying across. Before I mess things up by trying to add a new repository with an existing backup chain on it, is there a 'proper' way of doing this. I have seen a KB article for repositories that are created using SMB/Shared Folder but not for Windows Server repositories created using IP address.

Thanks
Alex

Hi Alex,

Just to be sure:
1. You have a VBR server, and an additional server which is your repository. You added this by IP-address and not by hostname. Is that correct?
2. You will change the IP of that repository server to another subnet (and I assume the networking part is all ready)

If this is the case:
Personally I have never done this type of operation but: One of the great things about B&R is that you won't need to recopy. If you are going to re-ip it, then chances are big that you will need to re-add it to the infrastructure and do a rescan. Most probably you will need to change the jobs also to point to the "new" repository (so that they continue to use the correct chain. See here for more information: https://www.veeam.com/kb1729

Hi!

I've moved our test storage server to production and to another site.
I've changed the ip settings on our dns servers correspondingly.

The backup storage has been set in Veeam by it's name.
When I try to rescan the storage, it still tries connecting old IP address?
How can I change this?

Hi,

Please review this topic with a couple useful links containing solutions. Thanks!

[hyvokar]

cant add repository ; failed to connect installer service

cant add the new windows server ; the server by the same name already exists

cannot remove the server ; since it's used by the current repository

cannot remove the repository; since it's used by the offsite copy job.

So ended up deleting the whole job.
Server deleted with warnings, (could not connect to server, since it's still trying to use old ip address)

Added new server, added new backup repository, rescanned repository, decrypted the backups, created new backup copy job, mapped old backup...

This process should be simplified a bit.

Just out of curiosity - have tried the PS script mentioned in the KB article? Thanks.

[hyvokar]

Nope. Dont really see why I should change vcenter ip address if my backup repository changes IP.

[foggy]

You can change repository IP in the database using the same script.

[BLWL]

Can confirm that IP address change of repository (and vCenter) works with the Powershell command described in KB1905. VBR 9.5 Update 4a.

https://www.veeam.com/kb1905

[veremin]

Basically the script works for every managed server added to backup server. In the KB we've just taken vCenter as an example. Thanks!

[ND40oz]

Does anyone have a new link to kb1905, the current one just takes me to the kb results search page.

[veremin]

Try the following example and see whether it helps:

Code: Select all

Asnp VeeamPSSnapin
$server = Get-VBRServer | ?{$_.name -eq "IpOfVC"}
$server.SetName("NewIP")

Before executing the script back up backup server configuration.

Thanks!

[ND40oz]

Thanks! Did we lose access to the older KBs though, be kind of nice to see the full write up on it?

[foggy]

The KB was pulled out due to the issues the described method might cause, so it needs to be updated. Please restart the Veeam Backup Service after applying the script, should help to avoid undesirable consequences.

Just to tag onto this one. I'm trying to change the IP of a SMB repository. When I run "get-vbrserver", it doesn't list my SMB repository at all so I can't change it. It lists things like my vCentre server, my ESXi servers, etc but not my SMB storage. Any ideas?

@lightsout

foggy has already posted the procedure. I don‘t think, it has changed since then. A SMB Repo is not a managed server. Because of that, you cannot use the mentioned powershell method

veeam-backup-replication-f2/change-nas- ... 54873.html

[lightsout]

Thanks, that is a shame. So:

1. My SMB repo is in a scale out backup repository.
2. It responds on the old & new IP addresses.

So what happens if I add the new IP address to the SOBR, and the remove the old one, and then re-scan? Should that work fairly seamlessly?

[Mildur]

do you have a support contract with veeam? I think, they have a solution for that. Changing the ip in the database or something like that. There must be some solution.

Do not change the ip by yourself in the database, it‘s not supported

Another options is veeam v10. There will be a evacuate feature for SOBR.
You can evacuate all backups from the old ip extend and they will get copied to the new ip adress extend. If you can add both the sametime and have enough storage for the copy process.

[foggy]

So what happens if I add the new IP address to the SOBR, and the remove the old one, and then re-scan? Should that work fairly seamlessly?

Yes, should work even without evacuation. Thanks!

[lightsout]

So what I did:

1. Add the new SMB server (by DNS this time too to avoid this biting me again!).
2. Edited the SOBR, removed the existing SMB server and added the new SMB server, at the same time.

It worked!

Hello,

Currently using B&R 9.5 u4 backing up to Exagrids.

I am in the process of creating SOBR repositories, 3 have gone really well. On the final one, the Exagrid has a 1GB and a 10GB interface configured and Veeam is using the 1GB interfaces of the extents rather than the 10GB interfaces which i would like them to use. I didn't realize this until this morning after about a week of jobs running. I'm wondering if there is a process to edit the ip addresses of the extents in the SOBR, other than starting from the beginning.

Thanks for any assistance.

Stay safe!

Jeff

You should be able to change IP address of particular SOBR extent, using the approached mentioned in the KB above. Thanks!

[Technogod]

I had the same problem. I wasn't able to get the PS script to work. I had to perform the same operation as hyvokar, Painful! I'm now using the hostname to hopefully alleviate this problem in the future.

[veremin]

Do you remember any specific issues you got with the script? Thanks!

[Technogod]

I'm not familiar with PS. I received an error no matter what variables I tried to use.

[veremin]

OK, next time you try to change IP address of repository automatically and come across the same issue, let us know, we will assist you with fixing the script. Thanks!

[Technogod]

KB1905 worked for me. I installed a Unifi Dream Machine to replace my pfSense box. So my IP changed due to the MAC address change. DR Host could no longer see Main Host. This saved me a ton of time.

Hey Guys,

I've opened a case below #05068350... (i removed sensitive information)

"We recently added a remote Windows Repository, actually we don't know how it's been working in the first place since we forgot a letter in the domain name part of the FQDN:

Hostname (Wrong)
XXXXITTBKP01.xxbicomxxxxxxx.local

Hostname (Correct)
XXXXITTBKP01.xxbiOcomxxxxxx.local (we forgot the "o")

Today we tried a FLR and an error regarding DNS ("Host not known") came up, so we managed to insert in the Windows Host File an alias to the wrong hostname, and worked.

So, is there any way to change the Windows Hostname without having to remove it from Veeam Infrastructure? It is part of a SOBR Performance Tier and S3 Capacity Tier enabled, we'd like to avoid any configurations changes, maybe an database update...
"

We are not familiar with PowerShell commands so I'd like to ask if anyone here has ever gone through this situation?



Thanks.

Hello,
did you try KB1905 already?

Thanks,
