When SQL Transaction Log Backup is enabled, Veeam Agent for Microsoft Windows copies transaction log files from the log archive destination (set by the Microsoft SQL Server administrator) to a temporary folder on the server. By default the path is: C:\ProgramData\Veeam\Endpoint\SqlLogBackup.

To change the location where the SQL Transaction Logs are temporarily stored, create the following registry entry on the server.

Note: This registry change is to be made on the machine where Veeam Agent for Microsoft Windows is installed and is running the backup with SQL Transaction Log backup enabled.

Key: HKLM\SOFTWARE\Veeam\Veeam Endpoint Backup
Type: REG_SZ (String Value)
Name: SqlTempLogPath
Value: Path to desired location (without trailing backslash)

Example

• For managed by VBR Failover Cluster type logs, the path should be HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication. The key should be created manually in the Agent machine registry if it does not exist.
• Starting with Veeam Backup and Replication 9.5 Update 4 (Veeam agent for Windows 3.0.1.1039), if the entered path is not valid, Veeam Agent will select an NTFS/ReFS volume having the most free space.
