Status Is a defect

Backup of subdirectories within Windows CIFS SHARES recursively processed despite of deactivation with dsmc incr subdir=no

In spite of setting the option subdir=no for incremental file backup, mounted CIFS Shares on Windows File Server will be processed recursively.

The reason for this behaviour is caused by an unsuccessful execution of the NetShareGetInfo function with the following error information:

NetShareGetInfo failed with RC=5

GetShareGetInfo() rc = 5
ERROR_ACCESS_DENIED
The user does not have access to the requested information.

Hence, permission problems at File and Share-level are responsible for ignoring the option subdir=no with the unwanted backup of subdirectories as a consequence. Not only that backup time takes twice as long as normal but it also turned out that backup time window is not sufficient. As a consequence, tape drives are reserved and not modified data is backed up in vain at the expense of versioning.

We ask for an option in the backup command that ensures that subdirectories are not backed up and ignored in the described context.

    This appears to be defect. IBM will reopen the support case.

    Hi,
    just to be clear I'm in no way associated with SW support, but I wonder if you have tried to open SW call for this behavior? It kind of seems like this could be bug for fixing, rather than feature request.
