Hello:
I am pondering the following -- would it be possible to use duplicity as
a way to sync changes between a number of systems in a more efficient
manner than rsync proper.
Example:
I have host0:/srv/bajillionfiles and host[1-9]:/srv/bajillionfiles
The contents of "bajillionfiles" change frequently, but not by a lot.
Running rsync between host0 and host[1-9] is extremely inefficient,
because for each 9 hosts it has to chew throw a bajillion files and
compare them with host0.
It would seem to me that using duplicity I can just do it once, on host0
and create "difftars" that I can distribute to host[1-9] that would only
contain the changes. Is there a way to take these difftars and "replay"
them on host[1-9] using duplicity?
And if not, whom do I bribe to make this possible? :)
Best,
