Thanks to all for jumping in on this one. I've used rsync in a kind of offhand manner for years, only now was it necessary to "get serious" with it....
So then, using -a **includes** -r? Goodness me, I was using -ra so who knows what gnarliness I was actually causing!! If I can briefly say what is going on, a 9.4GB dataset changes by about +50 MB per day, and is rsync'd once a day. If I deliberately run rsync again right after it finished a run with the combo "-rahvz" it ambles through the tree, obligingly lists everything, then - concluding there's nothing to be done, emits a human readable summary and exits. Unfortunately this takes a rather long time, and accomplishes (of course) nothing, since there's nothing to sync, but while essentially doing nothing, nevertheless chews up some significant resources. What is a more intelligent approach? -C On Mar 1, 2012, at 20:40, Kevin Korb <k...@sanitarium.net> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Yes, -a includes -r and a bunch of other things. > > - --no-i-r disables the incremental recursion and forces rsync to hold > the entire tree in memory in addition to fully scanning the tree on > both ends before copying anything. > > On 03/01/12 14:39, Elliot Wilen wrote: >> On Mar 1, 2012, at 11:34 AM, Kevin Korb wrote: >> >>> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 >>> >>> Without -r rsync will ignore all directories even if the path >>> you specified is a directory.
