Job Queue Log Files Consume a Large Amount of Disk Space

Valid on Windows platforms.

Symptom

The Job Queue log files are consuming a large amount of disk space on the Arcserve Backup server.

Solution

Arcserve Backup stores debugging information about the Job Queue in one or more log files named JobQueue.log. The log files are stored in the following directory on the Arcserve Backup server:

%HOME%\LOG

Example:

C:\Program Files\CA\ARCserve Backup\LOG\JobQueue.log

As the log files reach a specified size (for example, 300 MB), Arcserve Backup renames the log file and creates a new Job Queue log file.

Based on the following conditions, the Job Queue log files can consume a large amount of free disk space on the backup server:

• Quantity of agents and nodes you are protecting
• Quantity of scheduled jobs

Arcserve Backup lets you control the size and quantity of the Job Queue log files by doing the following:

1. From the Arcserve Backup server, open Windows Registry Editor.
2. To limit the size of the log files that Arcserve Backup generates, open the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\Base\QueueSystem\DebugFileSize

3. Modify the value as required:
   • Default: 100000000 bytes (approximately 100 MB)
   • Range: 10000000 bytes (approximately 10 MB) to 1000000000 bytes (approximately 1 GB)
   • Recommended value: 100000000 bytes (approximately 100 MB)
3. To limit the quantity of log files that Arcserve Backup retains, open the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\Base\Task\Common\JobQueueMaxFiles

4. Modify the value as required:
   • Default: 10
   • Range: 5 to 30
   • Recommended value: 10
4. (Optional) To decrease the level of debugging detail, create the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\Base\QueueSystem\DebugLevel

5. The values for this key are as follows:
   • Range: 1 to 5
   • Recommended value: 3

   Note: A higher value increases the level of debugging detail.

6. Specify a value of 1 or 2.

Be aware of the following:

• Values too low--Arcserve Backup may not be able to provide you with a sufficient level of information to debug problems.
• Values too high--The log files may consume too much free disk space on the backup server.
