I need to manage a filesystem with a large number of files (hundreds of thousands).
This filesystem is
rsynced periodically. The vast majority of files don't change often, but since there's so many, rsync takes a long time, because it has to
stat all of them.
In an effort to reduce the time
rsync takes, I've been
taring big directories that aren't changed, but this leads to usability problems. Every time a user needs a file inside of the archives, they must open the archive and extract the file.
Is there a way to make
rsync faster on such a scenario, with the change being transparent (or at least not annoying) to the non-technical user?
