Purpose

This article documents the procedure for implementing database partitioning to improve the performance of Veeam ONE deployments where the database in use was first created using Veeam ONE 9.x or older.

Starting with Veeam ONE version 10, all newly deployed Veeam ONE databases are already configured with partitioning. However, Veeam ONE deployments that were upgraded from the older versions (8.x, 9.x) do not have database partitioning automatically applied. For such databases, database partitioning must be applied manually.

Solution

Check Database Partitioning State

Use the following SQL query to check the current database partitioning implementation state. The output message will advise you on what actions need to be taken.

IF EXISTS (SELECT * FROM information_schema.views WHERE table_schema = 'monitor' AND table_name = 'PerfSampleDay')
    PRINT 'Modern database partitioning is already implemented. No actions are required.';
ELSE
    IF EXISTS (SELECT * FROM sys.partition_schemes WHERE name IN ('Low_ps_dt', 'Med_ps_dt'))
        PRINT 'Legacy database partitioning detected. Contact Veeam Support for assistance upgrading to modern database partitioning.';
    ELSE PRINT 'No database partitioning detected. Use the script on veeam.com/KB4175 to apply modern database partitioning.';
GO
                
            

Implementing Modern Database Partitioning

Stop the Veeam ONE services.
Back up the Veeam ONE database.
Download the Veeam ONE Partitioning SQL script.
Execute the script against the Veeam ONE database to deploy the necessary procedures.
Activate the partitioning process by executing the following SQL commands:
^{Depending on the size of the database, this process may take some time. You can check the progress of applying the partitioning in the SQL Studio "Messages" panel.}

EXEC monitor.sp_convert_perf_table 'PerfSampleMed', 604800, 86400
DECLARE @RetentionPolicyPeriod_Sec bigint = (select top 1 coalesce(RetentionPolicyPeriod,12) from common.ServerSettings)*2629746
EXEC monitor.sp_convert_perf_table 'PerfSampleDay', @RetentionPolicyPeriod_Sec, 2678400
EXEC monitor.sp_convert_perf_table 'PerfSampleLow', @RetentionPolicyPeriod_Sec, 2678400
                
            

When the process is complete, all three tables will be partitioned and ready to use.

Start the Veeam ONE services.

More Information

Historical note: This article uses the qualifier "Modern" in reference to the Veeam ONE 10 and newer implementation of database partitioning to differentiate from the optional database partitioning scheme that was available for Veeam ONE versions 8.x and 9.x. The optional database partitioning method that was created for Veeam ONE 8.x and 9.x, was functionally quite different than the method used by Veeam ONE version 10 and newer, and is now referred to as the Legacy Database Partitioning to differentiate it from the method used by Veeam ONE version 10 and newer, which this article refers to as Modern Database Partitioning.
