Veeam Backup & Replication 12.2 (build 12.2.0.334) has been recently released and it’s already available for download.
But before upgrade to this version, it’s better read carefully the related release notes (and the upgrade notes included!).
Features no more available or changed from previous versions
Are you using installations of Veeam Backup & Replication and Veeam Backup for Microsoft 365 on the
same machine? First upgrade Veeam Backup for Microsoft 365, second upgrade Veeam Backup &
Replication.
Are you using File to Tape jobs? Consider the following: They have been re-engineered for scalability and are no longer free with Veeam Backup & Replication 12.2. You will have a grace period of 3 months following the upgrade to Veeam Backup & Replication 12.2, during which your existing jobs will not consume a license. For more information, see Instance Consumption for Object Storage Backup, File Backup, and File to Tape Jobs.
Do you have any jobs using the Transform previous backup chains into rollbacks option? This option has
been removed from the product, and such jobs are no longer supported. For more information, see
Veeam KB 4390 (https://www.veeam.com/kb4390).
Are you using Veeam Backup Starter? This edition has been discontinued, so Veeam Backup &
Replication 12.2 will not accept such a license file. Please download a replacement license file from
the Customer Portal before upgrading.
Requirements
Veeam Backup & Replication 12.2 uses the same license file format introduced with version 10, so you
can use your existing version 10/11 license file to install version 12.2.
If you start from Veeam Backup & Replication 12.1, the resource requirements remain the same:
- CPU: x86-64 processor (minimum 4 cores recommended).
- Memory: 4 GB RAM plus 500 MB RAM for each concurrent job.
- Disk Space: 5 GB for product installation and 4.5 GB for Microsoft .NET Framework 4.7.2 installation. 10 GB per 100 VM for guest file system catalog folder (persistent data). Additional free disk space for Instant VM Recovery cache folder (non-persistent data, at least 100 GB recommended).
- Network: 1 Gbps or faster for on-site backup and replication, 1 Mbps or faster for off-site backup and replication.
- High latency and reasonably unstable WAN links are supported.
Same for the OS requirements that remain the same from v 12.1.
For the network ports, please note that starting with Veeam Backup Enterprise Manager 12, a new port (port 9405) is used for certificate communication between Enterprise Manager and Veeam Backup & Replication. Ensure that your firewalls are configured to take into account this new port to avoid communication issues between Enterprise Manager and Veeam Backup & Replication.
And you will need a lot of free space on you Veeam Server to perform the upgrade!
For the required space on disk, the minimum disk space is calculated on the flight after the system configuration check during the upgrade procedure. It is based on the list of required packages to be installed on the machine and usually is about 9 GB. We recommend providing 35 GB of disk space: 3 x ISO size (30 GB) in the selected installation path (for example, D:\VBR) plus 5 GB for the database operations on the system volume (for example, C:).
Perform a Veeam Configuration backup, as described in Running Configuration Backups Manually.
Ensure you have configuration backup encryption enabled. Otherwise, stored credentials will not be
included in it.
Upgrade steps
In order to upgrade properly to Veeam Backup & Replication version 12.2, you must run version at least version 11a (build 11.0.1.1261) or later. To upgrade from previous versions, contact Veeam Technical Support to found a proper upgrade path.
The main steps of the upgrade procedure are:
- Download the latest ISO version since it will have the latest available cumulative patch built in.
- Apply all Windows updates.
- If you have Enterprise Manager, remember to update it before VBR!
- If you use remote backup consoles, upgrade them manually using the product ISO file. Unfortunately, if you upgrade from versions earlier than 12 (build 12.1.0.2131), the automatic upgrade is not supported due to the major version number change.
- Ensure there are no active processes, such as any running jobs, restore sessions, CDP policies, … Is better to do not stop running jobs and let them complete successfully instead. Disable any periodic and Backup Copy jobs so that they do not start during the upgrade.
- If you are using an external database, perform a backup of the corresponding SQL Server configuration databases used by the backup server so that you can easily go back to the previous version in case of issues with the upgrade.
- If Veeam Server is running on a VM consider to take a cold clone. Using VM snapshots could slow down the upgrade process (and will take a lot of time for the consolidation after the upgrade).
- Mount the product ISO and use autorun or run the Setup.exe file. Click Upgrade in the Veeam Backup & Replication 12.2 splash screen.
- Plan your downtime properly… it takes time… a reboot to install some dependencies and a lot of time (and free space on C: because some components are there) for the upgrade. In a production environment with 1000 VMs it requires around of 40GB of free space and more than 30 minutes!
- I suggest a final reboot to be sure that everything start correctly.
- Check if all componets are updated.
- Re-enable the jobs.
Post upgrade
Are you using a customized AntivirusInfos.xml file? During the upgrade, Veeam Backup & Replication
will replace it with the default file. Make sure that you save your customized file at another path and
make necessary changes to the default file after the upgrade.
Note the the new version include PostgreSQL 15.8.1 (previous Veeam v12.x versions use old PostresSQL versions). This will not be upgraded (if you have used the embedded database deployment). If you need to upgrade the database software, follow the Upgrade the embedded PostgreSQL in Veeam Backup 12 article.
And of course, the Windows Server operating system remain the same. If you plan to upgrade the OS, could be better build a new system and migrate the configuration (although an OS in-place upgrade is technically possible in several cases).
Are you using Veeam Disaster Recovery Orchestrator? If yes, note that Veeam Disaster Recovery Orchestrator 5.0 is compatible with Veeam Backup & Replication 11 and 11a, Veeam Disaster Recovery Orchestrator 6.0 — with Veeam Backup & Replication 11a and 12, Veeam Disaster Recovery Orchestrator 7.0 — with Veeam Backup & Replication 12, 12.1 and 12.2. If necessary, upgrade Veeam Disaster Recovery Orchestrator before upgrading to Veeam Backup & Replication 12.2.
