Veeam is a popular choice for backup and data management in virtual environments. However, like any technology, it may encounter certain challenges that can hinder its optimal performance. Today, I’ll explore some common problems with Veeam and provide practical solutions to overcome them. By implementing these best practices, you can better protect your data and enjoy more efficient operations.
5 Common Problems You May Encounter with Veeam
While Veeam is a powerful and reliable solution, it’s essential to be aware of potential challenges that might come up during its usage. Here are five common problems that Veeam users may encounter and some practical insights on how to overcome them.
1. Backup Challenges
Snapshot Issues
One common problem with Veeam backups is dealing with snapshots in vSphere. These snapshots are essential for point-in-time copies of virtual machines, but if they are not managed properly, they can slow down your backups, causing delays and potential disruptions.
Guest Indexing
Guest indexing can also cause issues. Unless you have Veeam Backup Enterprise Manager, you should disable guest indexing during backups. Enabling guest indexing can significantly extend backup times. Opt for alternative indexing options or consider upgrading to Veeam Backup Enterprise Manager if necessary.
2. Licensing
Standalone Backup Agents
If you are using standalone backup agents, be aware that they consume license points against the Veeam Service Provider Console (VSPC) license. This is normal behavior, so plan your licensing requirements accordingly to avoid any unexpected limitations.
Revoking Licenses from Removed Workloads
Removing a workload from Veeam Backup & Replication (VBR) may lead to license-related issues. Make sure to follow proper procedures to revoke licenses from removed workloads and avoid any licensing conflicts.
3. VSPC
False RPO Alarms
Recovery Point Objective (RPO) defines the maximum acceptable data loss during a disaster or failure. False alarms occur when VSPC mistakenly triggers alerts, suggesting that the set RPOs are not being met, even though backups are running fine.
These alarms may happen due to temporary network issues or resource limitations during backups. They can also be caused by storage problems or performance bottlenecks. To handle false RPO alarms, check your network, optimize resources, and review backup reports to ensure genuine RPO breaches.

Disconnected Backup and Replication Servers
After configuring Veeam 12 with Multi-Factor Authentication (MFA), you may encounter issues with disconnected servers or management agents in VSPC. To resolve this:
- Set up a local service account with local administrative permissions
- Assign the Veeam administrator role in VBR
- Exempt the account from MFA
- Configure the Veeam management agent service to log in using this account.
Unmonitored Backup Agents
In a Veeam environment, agents play a crucial role in backing up physical machines or workloads that might not be virtualized. These agents provide an essential layer of protection for critical data residing outside the virtual infrastructure.
It’s important that all backup agents are managed and activated in the VSPC. Failure to monitor and alert on backup agents can lead to potential data loss or unprotected workloads.
4. Multi-Factor Authentication (MFA) issues
When setting up MFA, an error stating an incorrect code is common. To fix this, verify that the clocks on both devices are synchronized and correct.
5. Immutable backups
During installation, Ubuntu Server LTS 22.04 or LTS 20.04 might crash repeatedly. To resolve this, disconnect network cables and adapters, and ensure that hard drives do not have a broken or pre-existing RAID configuration. If necessary, wipe the drives completely or disconnect them for a successful installation.
Best Practices for Microsoft SQL Server in Veeam
A well-maintained and optimized VSPC environment ensures that your data protection services run smoothly. By sticking to these Veeam best practices, you can enhance the reliability, performance, and security of your deployment.
1. Configure a Separate Disk for SQL Server Database
For better performance and isolation, configure a separate disk or storage volume for the Microsoft SQL Server database used by VSPC. This separation helps avoid conflicts with other system processes and prevents database performance issues.
2. Create a Maintenance Plan for Regular Backups
Create a maintenance plan for regular backups of the VSPC database. Regular backups safeguard against data loss and provide a recovery point in case of any unforeseen issues with the database. Schedule these backups during periods of low system activity to minimize any impact on the VSPC’s performance.
3. Limit SQL Memory Usage for All-in-One VSPC Installation
If VSPC and SQL Server are on the same server, limit SQL’s memory usage to 8GB. This ensures enough resources for VSPC and avoids potential memory problems.
4. Encrypt Backups
Keep your data secure by enabling encryption for VSPC backups. This protects sensitive information and prevents unauthorized access.
5. Configure Immutability
To protect your backups from ransomware attacks and accidental deletions, implement immutability settings on your backup repositories. Immutability ensures that backup files cannot be modified or deleted for a specified period, adding an extra layer of protection to your data.
6. Run Regular Maintenance on Backup Files and Repositories
Perform regular maintenance on backup files and repositories. Clean up deleted data, defragment repositories, and check for any errors to optimize storage and backup performance.
7. Backup Over Storage
Consider using backup over storage instead of network-based backup, as it often gives you better and faster results. By backing up directly to storage, you reduce the time spent troubleshooting network-related issues and end up with a more efficient backup process.
