Agent Log Files

Arcserve Backup includes log files that provide you with details about backup operations executed using the Agent for Virtual Machines. Arcserve Backup stores the log files on the backup proxy system and the Hyper-V host system in the location that follows:

C:\Program Files\CA\ARCserve Backup Client Agent for Windows\Log

The log files that follow apply to VMware VM backups:

recovervm.log

Lets you view information about Recover VM recovery operations.

ca_vcbpopulatedb.log

Lets you view messages about VMware VM backup jobs.

The messages are prefixed by the Job ID number and the Session number, which lets you distinguish jobs that are running simultaneously.

Maximum log size--By default, the agent limits the size of ca_vcbpopulatedb.log to 250 kb. To change the limit (increase or decrease the limit), create the registry that follows:
```
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VMMaxLogSize
```
Value data: Specify the maximum log size that you require.

mount_jnl.log

Lets you view information about mount and unmount operations.

The log file contains the parameters specified for each mount and unmount operation.

ca_vcbmounteroutput_xxx.log

Lets you view information about mount and unmount operations that fail.

Maximum log count--By default, Arcserve Backup saves a maximum of 1000 log files. You can specify a different number of log files by modifying the Value data in the registry key that follows:
```
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VMMaxLogFiles
```
Note: When the number of ca_vcbmounteroutput_xxx.log logs reaches the maximum value, Arcserve Backup overwrites ca_vcbmounteroutput_000.log on the next mount operation and deletes ca_vcbmounteroutput_001.log.
Maximum mount log size--By default, the agent limits the size of ca_vcbmounteroutput_xxx.log to 250 kb. To change the limit (increase or decrease the limit), create the registry that follows:
```
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VMMaxMountLogSize
```
Value data: Specify the maximum log size that you require.

The log file that follows applies to Hyper-V VM backups:

Hyper.log

Lets you view messages about Hyper-V VM backups and restores.

The messages are prefixed by the Job ID number and the Session number, which lets you distinguish jobs that are running simultaneously.

The log file that follows applies to VMware and Hyper-V VM backups:

vmdbupd.log

Lets you view information about auto-populate executions.

The log file contains the parameters specified and the status of all automatic executions of Arcserve VMware Configuration Tool and Arcserve Hyper-V Configuration Tool.
