Well, feel free to sponsor such a feature or provide a patch.

Keep in mind that any solution would need to work through Horde's API  
and work with any of Horde's available storage backends, for all  
systems that would need to be backed up. This can include anything  
from SQL, IMAP, IMSP, LDAP, NoSQL, filebased storage and any  
interconnections between any "recovered" objects such as permissions  
etc... Also, as already indicated in some cases it won't be possible  
to recover properly due to things like autoincrement fields and such.

Again, feel free to sponsor this feature if it's a requirement for you.
