Off-Host Backup proxy servers will retrieve VM data from the source datastore, process it and transfer it to the destination. The off-host backup proxy removes unwanted overhead on the production Hyper-V host.
Suppose you plan to use backup infrastructure components and servers that you plan to use for various types of restore operations. In that case, you must add the Linux servers to the backup infrastructure.
Suppose you plan to use as backup infrastructure components and servers that you plan to use for various types of restore operations. In that case, you must add the Microsoft Windows servers to the backup infrastructure.
Veeam Backup & Replication can perform backup, replication, and file copy operations on Microsoft Hyper-V VMs whose discs are located on Microsoft SMB3 file shares.
You must add the Microsoft Hyper-V clusters you plan to use as source and target for backup, replication and other activities.
You must add the Microsoft Hyper-V standalone hosts you plan to use as source and target for backup, replication and other activities.
To gain remote access to Veeam Backup & Replication v12, you must first upgrade the Veeam Backup & Replication console to v12 on a dedicated machine.
When you install Veeam Backup & Replication, the Veeam Backup & Replication console is automatically installed on the backup server. If you want to access Veeam Backup & Replication remotely, you can install the Veeam Backup & Replication console on a dedicated machine.
Microsoft SQL Server Express has a configuration data storage limit of 10 GB. The Express Edition is sufficient for the evaluation and small environments (500 VMs).
PostgreSQL is free and has no size limit or compute restrictions has improved performance over SQL Express.
Veeam Backup and Replication v12 launched on Feb 14, 2023. If you are still using an older version, it is time to upgrade it to v12. To upgrade Veeam Backup & Replication to version 12, you must have version 10a (build 10.0.1.4854) or later installed on the supported operating system.
You can choose Microsoft SQL as a Veeam Backup & Replication database. You were installing a Microsoft SQL Server (or Express), either locally on the backup manager server or remotely. If Microsoft SQL Server is not already installed. In that case, the Veeam Backup & Replication won’t install the Microsoft SQL Server Express Edition on the backup server automatically. You must install it before installing Veeam Backup and Replication v12 version.
When you install Veeam Backup & Replication, the Veeam Backup & Replication console is automatically installed on the backup server.
You can choose PostgreSQL as a Veeam Backup & Replication database. It has no size limit or computes restrictions and has improved performance over SQL Express.
This error is common if the Exchange Servers use Antivirus endpoint software or a backup agent. The antivirus software or backup agent will impact the stopping services process.
When I tried to prepare the AD schema for installing Exchange 2016 CU23, and it happened the error message is below.
“Setup can’t continue with the upgrade because the powershell has open files” error message.
Let’s fix it.
Today, I helped a client migrate Exchange from 2010 to 2019. As you know, Exchange 2010 can’t migrate to 2019 directly. You need to migrate Exchange from 2010 to 2016 and then 2019.
When I tried to prepare the AD schema for installing Exchange 2016 CU23, and it happened the error message is below.
“One or more servers in the existing organization are running Exchange 2000 Server or Exchange Server 2003”.
The error is because they were not uninstalled Exchange 2000 or 2003 completed. Let’s fix it.
Microsoft released Windows patches on the second Tuesday of every month. This procedure installs Microsoft Windows server patches for the production cluster servers without an outage.
There are many ways to rebuild the Hyper-V host, but I will show you how to rebuild a Microsoft Hyper-V host via Virtual Media. These screens captured were for Windows Server 2019, but not for Windows Server 2019 only. You can use Windows Server 2022 ISO image file too.
Vulnerability in this Veeam Backup & Replication component allows unauthorized users to obtain encrypted credentials stored in the configuration database. The vulnerability may lead to these unauthorized users gaining access to backup infrastructure hosts. The vulnerable process Veeam.Backup.Service.exe (TCP 9401 by default) allows unauthenticated users to request encrypted credentials.
Veeam released new patches to fix this vulnerability on March 7, 2023. No Hosts restart is required after installing this patch.
