Use the Backup Agent bbtrace.txt log files to understand and resolve any errors that may occur with the Backup Agent such as an initialization error. Each time the Backup Agent Service is restarted, a number is appended to the current bbtrace.txt file, and a new file is generated.
To review the log file:
- Log in to the data source that is failing to back up data, and go to the Backup Agent log files. By default, the log files are located in:
C:\Program Files\Barracuda\Barracuda Backup Agent\log
Locate the file bbtrace.txt; this is the most recent log file.
- Open bbtrace.txt in Notepad. This file contains data that is helpful in determining the specific error. Each log entry is time stamped, so you will first want to identify when the failed backup occurred based on the Report details page; note that there may be multiple days of log details so it is recommended that you use the search function to find the error.
Search the log file for terms such as Failed or Critical. Once you locate the term, review the associated content to determine the specific error message:
In this example, a VSS snapshot failed due to an unexpected operating system error on the targeted server.
With most errors located in bbtrace.txt there are generally errors or warnings located within Application/System Event logs. Barracuda recommends taking the timestamp within bbtrace.txt, for example, 05/22/13 02:09:55, and looking at the event logs based on that timestamp.
