There are only a few days left until the German VMUG UserCon opens its doors.
Following an old tradition, the event will take place again at Kap Europa near the main train station.
An extensive agenda with sessions from VMware and community speakers as well as interesting practical examples from partners on VMware integrations are on the agenda. In between, there will be enough coffee breaks to network with other visitors.

Call for community sessions
Calling all tech enthusiasts and subject matter experts! Are you passionate about a specific VMware-related topic within the realm of advanced technology? At TechX 300, we’re excited to offer the opportunity to showcase your expertise through our Level 300 Community Sessions.
We believe in the power of community-driven knowledge sharing, and that’s why we’re opening the doors for you to contribute to the event. To apply for a Level 300 Community Session, simply submit your session proposal highlighting the key takeaways, the target audience, and the VMware-specific expertise required.
VMware will be sunsetting the NSX native load balancers. Customers should be migrating to the currently supported NSX Advanced Load Balancer (Avi) which simplifies operations today while getting you ready for your multi-cloud and container strategies tomorrow. Avi works across all environments beyond the NSX framework, expanding use cases to public cloud, containers and app security while adding capabilities for GSLB, WAF and analytics. A migration tool will be available to make the migration of your existing configuration to the current technology easy and painless.
The cosmetical “1970” bug mentioned in the blog post above has already been fixed in an interims release. With V1.2.0 now we get full CDP support. CDP in this context does not relate to Veeam’s functionality of the same name. DataCore maintains a feature with this acronym for at least 10 years already.
I also explained a workaround to leverage CDP rollback points with the old version of the plugin already. We will not need the workaround any more, as the plugin now detects CDP rollback points just like it detects snapshots on your SanSymphony volumes!
The first installation of the plugin is pretty straightforward and was also discussed already. To update your installation, the new version of the plugin can be installed on top of the old one. Just disable all jobs beforehand and wait for VBR to become idle. The installer will replace the plugin files within the path.
C:\Program Files\Veeam\Backup and Replication\Plugins\Storage\DataCore Software Corporation
Once installed and configured, VBR will detect all CDP rollback points you create from the DataCore console right away and will let you do all recoveries as with common snapshots. The difference is, that you do not need to have any snapshot schedules. Just enable CDP for your volumes. Only when necessary, create your rollback to the exact moment in time needed. Could e.g. be just a few seconds BEFORE the ransomware started to encrypt your fileserver. This allows to lower your RPO for all VMs to a few seconds.
In contrast to snapshots you are currently not able to generate rollback points from within your Veeam console. You have to jump to DataCores console. This is because some extra decisions have to be made to generate a rollback point:
Exact point in time to spawn the rollback point to
Type of the rollback point: either “Expire Rollback” or “Persistant Rollback”
The amount of time you can rewind depends on your license within DataCore on one hand and the size of the history buffer you reserved on the other. I would strive for at least 8h here, to allow for rolling back a regular working day. But more is even better of course. For a 24h buffer you would have to reserve your daily change rate as a history buffer at least. So have some extra disk space ready.
An “Expire Rollback” will automatically be disposed, once the rollback point in time moves out of this history buffer. This could of course be dangerous in a recovery scenario, as you would all of a sudden loose the valuable restore point. Maybe right in the middle of a recovery. This is why in the default settings only a “Persistant Rollback” will be detected by Veeam. But this can be changed of course. Read about the details in this whitepaper.
I would though recommend to stick with only detecting “Persistant Rollbacks”. Those rollbacks should preferably only be used with mirrored volumes. Here a rollback will still be secured once it reaches the end of the history buffer. Now the productive volume on the side of the history buffer will be disconnected. With a mirrored volume this will result in a volume running from only one side of your cluster. But your VMs will be available and so will the rollback point.
One should plan for CDP accordingly. Have an independent disk pool for your history buffer to minimize performance penalties. This buffer should offer the same performance rate as the productive pool does. I would recommend 32MB as a SAU (Storage Allocation Unit) size for the buffer pool. For the productive pool I usually stick to 128MB, though 1024MB is the default now. This enhances granularity for AST
