I guess it worked, because during the rsync, nothing was changed in the
tdb/ldb files, because it's a small test network. If you have a bigger
network, where the databases often changes, it could happen that this appears
during your rsync. Then you have a corrupt/inconsistent "backup".
I think for the tdb/ldb files tdbdump is a must.
In my backup script I run tdbbackup for all that files to generate the *.bak
of them and then tar the whole to a save place (with ext. ACLs). So I can copy
it back and have a hopefully save backup of the databases if neccessary.
On Rowlands initial question, how to to restore tdbbackup files:
I haven't tried it yet. But let me know if tdbrestore is the working way.
