Thanks Lorenz,

That could work if the DB is already deployed.

How about initial deployment on multiple nodes? Or vice versa – copying it up 
from live nodes to some backup/archive storage?

    Probably I misunderstand the workflow, but isn't it more efficient to
    push the changeset to all nodes instead of copying the whole TDB? I.e.
    synchronizing the TDB instances on the triple level instead of files.

the hardware OS is throwing errors just because there are big files on it 
(without even copying them).

copying and maintaining TDB files-- is that for high availability? Are you 
writing updates to a master and replicating the resulting store, or some other
