Although it is useful to have debug logs of all operations, it is necessary to control the size of the logs. In order to achieve this, SMS provides module specific debug logging:
For problems related to connecting to remote targets, debug logging for SMDR should be enabled. For example, if a backup application is unable to see a remote target SMDR, then enable debug logging for SMDR at the local and remote servers.
For problems that are related to backup or restore to a particular target service, debug logging should be enabled for that particular target service. For example, debug logging can be enabled for TSAFS to trace a problem where errors are received for a set of files.
As a general rule, if an issue is seen before connecting to a target service, enable debug logging for SMDR. If issue is seen after connecting to a target service, enable debug logging for the target service.
