Hello,
Check this:
You have several choices for exporting the data in your logs. You can export the data in some logs to a comma-delimited text file. You can export other logs' data to a tab-delimited text file that is called a dump file or to a Syslog server. Log data export is useful if you want to accumulate all logs from your entire network in a centralized location. Log data export is also useful if you want to use a third-party program such as a spreadsheet to organize or manipulate the data. You also might want to export the data in your logs before you delete log records.
When you export log data to a Syslog server, you must configure the Syslog server to receive those logs. To forward logs to third-party programs, you need to have the third-party program installed and on the network. For example, you can use Microsoft Excel to open the exported log files. Each field appears in a separate column, a separate log record in each line.
Note:
You cannot restore the database by using exported log data.
