The script was provided by sernet, so I guess it should be safe...

The question that remains is:

Can I just
- shutdown samba
- tdbbackup DC=DOMAINDNSZONES,DC=...ldb
- replace DC=DOMAINDNSZONES,DC=...ldb with the smaller .bak file
- start samba again

or do I need to make a dump/restore for *all* ldb files to keep 
everything in sync?
