NetWorker Module for Lotus - Notes API, error = 525

[doctor]

Backup client:
Windows Server 2003 SP2
Lotus Notes/Domino 8.5
NetWorker User for Lotus version 3.0.1

Backup server:
NetWorker 7.4.3

No matter I try to do the backup from the client side or the server side I get the following error message for all the databases in Lotus:

Ignoring D:\Domino\Data\mail\tsk.nsf that failed with error (NSFDBOpen() failed for D:\Domino\Data\mail\tsk.nsf with error = 525 (This database is currently in use by another person or process, and cannot be accessed at this time. In order to share a Notes database, it must be accessed via a Domino Server by all users of the database.).).

My nml.cfg file look like this:
# These are the parameters for the NetWorker Module for Lotus
lotus {
Notes_ExecDirectory = "D:\Domino"
NSR_BACKUP_PATHS = "D:\Domino\data"
NSR_SKIPDBERRORS = TRUE
NSR_CATALOGFILE = C:\WIN32APP\NSR\APPLOGS\NML.LOG
}

NetWorker Module for Lotus - Notes API, error = 525 Solution

Apparently this error message isn't uncommon when you have a partioned Domino Server. The solution is to use the NSR_CROSS_MOUNT_POINTS option - whereby the nml.cfg (in my case) will be:

# These are the parameters for the NetWorker Module for Lotus
lotus {
Notes_ExecDirectory = "D:\Domino"
NSR_BACKUP_LOTUS_DIR = TRUE
NSR_CROSS_MOUNT_POINTS = TRUE
NSR_SKIPDBERRORS = TRUE
NSR_CATALOGFILE = C:\WIN32APP\NSR\APPLOGS\NML.LOG
}

Finally the services are restarted on my 2 Domino servers
