Backup and Restore of Samba4

[Ashok Kumar J]

Dear sir,

         I have configured the Samba4 Active Directory in Debian server.
Now i want to do the backup of this server and this backup need not to be
overwrite the existing settings in the another Samba4 AD. ie, I saw the
samba-bakup tool for backup. But while restoring the backup, i should not
override the existing setup(means appending to the existing setup). please
provide your valuable information.
