Log Directory Location
Determines where log files created by Veeam Backup & Replication will be stored.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: LogDirectory
Value Type: String Value
Value Data: <path_on_server>
Default: C:\ProgramData\Veeam\Backup
- The path provided must be to a folder on a drive of the Backup Server, without the trailing slash.
- The path cannot be a remote location or mapped drive.
Maximum Individual Log File Size
A new file is created when a log file becomes larger than the specified value.
Example: Svc.VeeamBackup.log -> Svc.VeeamBackup_1.log
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: MaxLogSize
Value Type: DWORD (32-Bit) Value
Value Data: <value in KiB>
Default: 10240 (Decimal)
Maximum Individual Log File Generations to Retain
As an individual log file grows larger than the maximum size a new generation of log files is created. This registry setting controls the maximum number of generations of log files to be retained.
Example: Svc.VeeamBackup_1.log, Svc.VeeamBackup_2.log, Svc.VeeamBackup_3.log, etc.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: MaxLogCount
Value Type: DWORD (32-Bit) Value
Value Data: <##>
Default: 10
Maximum Total Size of Uncompressed Logs per Job Folder
When the total size of all uncompressed log files within a folder is greater than this value, all logs in the folder are compressed into an archive.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: UncompressedLogsMaxTotalSize
Value Type: DWORD (32-Bit) Value
Value Data: <value in KiB>
Default: 512000
Maximum Log Archive Generations to Retain
An archive is created when the total size of uncompressed log files within a folder becomes larger than the maximum size. This setting controls how many generations of those archives are to be retained.
Example: Svc.VeeamBackup.1.gz Svc.VeeamBackup.2.gz
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: LogsArchivesMaxCount
Value Type: DWORD (32-Bit) Value
Value Data: <##>
Default: 10
Log Files Stored on Windows Component Servers
For example Proxies, Mount Servers, Gateway Servers, Repositories, WAN Accelerators, Tape Servers, etc.
The following registry values must be created on the Windows component server.
After changing any of the following settings the Windows component server itself must be rebooted.

Log Directory Location
Determines where log files created by Veeam Backup & Replication will be stored.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: LogDirectory
Value Type: String Value
Value Data: <path_on_server>
Default: C:\ProgramData\Veeam\Backup
- The path provided must be to a folder on a drive of the server, without the trailing slash.
- The path cannot be a remote location or mapped drive.
Maximum Individual Agent Log File Size
A new file is created when a log file becomes larger than the specified value.
Example: Agent.DC.Source.DC.log -> Agent.DC.Source.DC.1.log
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: AgentMaxLogSize
Value Type: DWORD (32-Bit) Value
Value Data: <value in Bytes>
Default: 15728640 (Decimal)
Note: The max agent log size is not precise. Sometimes, a log file may not rotate until a process thread is complete. There will be slight deviations from the maximum value set.
Maximum Individual Log Generations to Retain
As an individual log file grows larger than the maximum size a new generation of log files is created. This registry setting controls the maximum number of generations of agent log files to be retained.
Example: Agent.DC.Source.DC.1.log, Agent.DC.Source.DC.2.log,Agent.DC.Source.DC.3.log etc.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: AgentMaxLogCount
Value Type: DWORD (32-Bit) Value
Value Data: <##>
Default: 10
Log Files Stored on Linux Component Servers
For example Proxies, Mount Servers, Gateway Servers, Repositories
Agent Log Controls
The settings in this section control log files with filenames containing the word "Agent" that are written by the veeamagent process.
(Example: Agent.<jobname>.<vmname>.Target.log )
The following settings must be entered within the /etc/VeeamAgentConfig file on the Linux component server.

Maximum Individual Agent Log File Size
If the
/etc/VeeamAgentConfig file is not present on the Linux machine, you must first create it.
A new file is created when a log file becomes larger than the specified value.
Example: Agent.DC.Source.DC.log -> Agent.DC.Source.DC.1.log
Config File Location: /etc/VeeamAgentConfig
Entry Name: AgentMaxLogSize
Data: in BYTES
Default: 15728640
Example: AgentMaxLogSize=67108864
Note: The max agent log size is not precise. Sometimes, a log file may not rotate until a process thread is complete. There will be slight deviations from the maximum value set.
Maximum Individual Agent Log Generations to Retain
If the
/etc/VeeamAgentConfig file is not present on the Linux machine, you must first create it.
As an individual log file grows larger than the maximum size, a new generation of log files is created. This setting controls the maximum number of generations of agent log files to be retained.
Example: Agent.DC.Source.DC.1.log, Agent.DC.Source.DC.2.log,Agent.DC.Source.DC.3.log, etc.
Config File Location: /etc/VeeamAgentConfig
Entry Name: AgentMaxLogCount
Data: <numeric value>
Default: 10
Example: AgentMaxLogCount=32
Service Log Controls
The settings in this section control the log directory and the log files of the services deployed on the Linux server.
(Example: VeeamTransportSvc.log)
The following settings are located within the /opt/veeam/transport/VeeamTransportConfig file on the Linux component server.
Note: If the /opt/veeam/transport/VeeamTransportConfig file is not present, the Persistent Veeam Data Movers were not deployed on the Linux Machine.

Log Directory
This value controls the location where all log files will be written when the Linux machine is using persistent Veeam Data Movers.
Entry Name: BaseLogDirectory
Default: /var/log/VeeamBackup
Maximum Service Log File Size
A new file is created when a service log file becomes larger than the specified value.
Example: VeeamTransportSvc.log >> VeeamTransportSvc.1.log.gz
Entry Name: MaxLogSize
Default: 15728640
The value is defined in bytes and has a minimum value of 1048576.
Maximum Individual Service Log File Generations to Retain
As an individual service log file grows larger than the maximum size a new generation of log files is created. This registry setting controls the maximum number of those generations to be retained.
Example: VeeamTransportSvc.1.log.gz,VeeamTransportSvc.2.log.gz,VeeamTransportSvc.3.log.gz
Entry Name: MaxLogCount
Default: 10
