Was on mobile and made a mistake, my bad. Sorry.
Aw, shucks!

Peasant and MadeInGermany - thank you again, your solution worked.

Code:
umount /mnt/backup

cd /mnt/backup/
du -h
39G     ./servers-unix-hq/sugar.gnsa.local
39G     ./servers-unix-hq
4.5G    ./db-mysql-hq/sugar.gnsa.local
4.5G    ./db-mysql-hq
44G

Just like Peasant said, /mnt/backup was mounted on top of local directory with the same name. Once unmounted, the directory showed its true size.

nisrestore(1M)						  System Administration Commands					    nisrestore(1M)

NAME
nisrestore - restore NIS+ directory backup SYNOPSIS
nisrestore [-fv] backup-dir directory... nisrestore [-fv] -a backup-dir nisrestore -t backup-dir DESCRIPTION
nisrestore restores an existing backup of a NIS+ directory object that was created using nisbackup(1M). The backup-dir is the UNIX direc- tory that contains the NIS+ backup on the server being restored. The nisrestore command can be used to restore a NIS+ directory object or a complete NIS+ database. It also can be used as an "out of band" fast replication for a new replica server being initialized. The rpc.nisd(1M) daemon must be stopped before running nisrestore. The first synopsis is used to restore a single directory object or a specified list of directory objects. The directory can be partially qualified or fully qualified. The server being restored will be verified against the list of servers serving the directory. If this server is not configured to serve this object, nisrestore will exit with an error. The -f option will override this check and force the operation. The second synopsis will restore all of the directory objects contained in the backup-dir. Again, the server will be validated against the serving list for each of the directory objects in the backup-dir. If one of the objects in the backup-dir are not served by this server, nisrestore will exit with an error. The -f option will override this check and force the operation. The -a option will attempt to restore all NIS+ objects contained in the backup-dir. If any of these objects are not served by the server, nisrestore will exit with an error. If the backup-dir contains objects that are not served by the server, nisrestore must be executed with- out the -a option and the specific directory objects listed. The -f option will disable verification of the server being configured to serve the objects being restored. This option should be used with care, as data could be inadvertently restored to a server that doesn't serve the restored data. This option is required in the case of restoring a single server domain (master server only) or if the other NIS+ servers are unavailable for NIS+ lookups. The combination of options -f and -a should be used with caution, as no validation of the server serving the restored objects will be done. New replicas can be quickly added to a namespace with the nisrestore command. The steps are as follows. Configure the new replica on the master server (see nisserver(1M)): master# nisserver -R -h replica Temporarily stop the rpc.nisd server process on the new replica server: replica# svcadm disable -t network/rpc/nisplus:default Create a backup of the NIS+ database on the master, which will include the new replica information. See nisbackup(1M). The /backup will need to be exported to the new replica. See share_nfs(1M). master# nisbackup -a /backup Restore the backup of the NIS+ database on the new replica. Use the -f option if nisrestore is unable to lookup the NIS+ objects being restored. The backup should be available through nfs or similar means. See share_nfs(1M). replica# nisrestore -f -a //nfs-mnt/backup Restart the rpc.nisd(1M) process on the new replica, and the server will immediately be available for service: replica# svcadm enable network/rpc/nisplus:default OPTIONS
The following options are supported: -a Restores all directory objects included in the backup-dir partition. -f Forces the restoration of a directory without the validation of the server in the directory object's serving list. -t Lists all directory objects contained in backup-dir. -v Verbose option. Additional output will be produced upon execution of the command. OPERANDS
The following options are supported: backup-dir The UNIX directory that contains the data files for the NIS+ directory objects to be restored. directory The NIS+ directory object(s) to be restored. This can be a fully or partially qualified name. EXAMPLES
Example 1 Restoring the Directory Object on a Replica Server from a Local UFS Partition To restore the org_dir directory object of the domain foo.com on a replica server from a local ufs partition named /var/backup: replica_server# nisrestore /var/backup org_dir.foo.com. Example 2 Forcing the Restore of a Backed up NIS+ Namespace to a Replica Server From the Backup Partition To force the restore of an entire backed up NIS+ namespace to a replica server from the backup partition named /var/backup: replica_server# nisrestore -f -a /var/backup Example 3 Restoring the Subdomain on a Master Server From a Backup that Includes Other Directory Objects To restore the subdomain sub.foo.com on a master server, from a backup that includes other directory objects: master_server# nisrestore /var/backup sub.foo.com. org_dir.sub.foo.com. groups_dir.sub.foo.com. EXIT STATUS
0 Successful completion. 1 An error occurred. FILES
/backup-dir/backup_list This ASCII file contains a list of all the objects contained in this backup-dir directory. This information can be displayed with the -t option. /backup-dir/directory-object A subdirectory that is created in the backup-dir which contains the directory-object backup. /backup-dir/directory-object/data A subdirectory that contains the data files that are part of the directory-object backup. /backup-dir/directory-object/last.upd This data file contains timestamp information about the directory-object. /backup-dir/directory-object/data.dict A NIS+ data dictionary for all of the objects contained in this directory-object backup.

NIS+ might not be supported in future releases of the Solaris Operating system. Tools to aid the migration from NIS+ to LDAP are available in the current Solaris release. For more information, visit http://www.sun.com/directory/nisplus/transition.html. The NIS+ service is managed by the service management facility, smf(5), under the service identifier: svc:/network/rpc/nisplus:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. SunOS 5.11 13 Aug 2004 nisrestore(1M)
