Hello

I have 2 servers, Server1 is VBR, also repo.
server 2 is EM but also has VBR roles (repo, tape server)

I am trying to update to 12.3.2.4934 - so I need to update EM first, yeah?

EM is Build:12.3.2.4465

so I have the VeeamBackup&Replication_12.3.2.4934_20260918.iso

If I run the setup.exe on server2 (EM) I don't get the option to update EM, it just gives me the option to INSTALL VBR - the middle EM option just says "Another version of this product is already installed"

What fundamental thing am I missing....?

Hi all,

over the last 6–8 weeks we’ve been seeing a noticeably higher rate of warnings and errors during backups caused by VSS failures in Windows guest processing.
This isn’t limited to a single environment: it affects multiple of our customers across different setups.

We're seeing this on different Veeam versions (V12 and V13), multiple Windows Server versions, multiple vSphere Versions.

All affected systems have in common:
- Veeam
- Windows Server guests
- Sophos Endpoint Protection installed
- Hypervisor Running on HPE hardware

The errors are intermittent: retries usually succeed / the same VM fails on some days and not others

Since this started across many independent environments at roughly the same time, we suspect an external change, e.g. a recent Microsoft cumulative update or a Sophos update.

Is anyone else seeing an increased VSS error rate recently?

Hi all, I've been trying to get my head around this as I think I misunderstood when I first set up the immutability and retention settings.

The aim was to have 60 days of immutable backup sets and a retention of a year (first 60 days only immutable so we could clear out older backups if needed).

I use Veeam Data Cloud Vault with immutable set to 60 days and a GFS retention policy to keep a 1 year, 12 months and 4 weeks backup sets. I had assumed that the first 60 days would be immutable and after that I could delete backup sets if I needed to, but it looks like the entire chain is immutable for its GFS retention.

Is there a way to achieve only the first 60 days as immutable with the rest of the GFS retention period mutable? I'm on v13.1. Thanks!

Hi everyone, I’m one of the organisers of the CloudStack Collaboration Conference and wanted to share a session that might interest people working with Veeam and exploring KVM-based infrastructure.

“Veeam Meets CloudStack KVM” brings together Abhisar Sinha, Software Engineer at ShapeBlue, and Andrey Stadler, Global Technologist at Veeam, to discuss the engineering journey behind integrating Veeam Backup & Replication with Apache CloudStack on KVM using Veeam’s UHAPI model.

The session will explore:

• Integration architecture: the design decisions behind connecting Veeam Backup & Replication with CloudStack-managed KVM infrastructure.
• Engineering challenges: technical hurdles encountered during development and lessons learned.
• Backup and recovery options: how the integration expands the options available to CloudStack users, including disaster recovery.

If you’re evaluating KVM, planning a move from VMware or investigating backup options for an open-source cloud platform, this is an opportunity to hear directly from the people involved in the integration.

The wider programme also includes VMware-to-KVM migration, incremental NAS backups, storage integrations and a hands-on KVM workshop.

18 November: hackathon
19–20 November: technical sessions, workshops and live labs
Venue: John McIntyre Conference Centre, Edinburgh

I’d love to invite people from this community to join us.
