Sounds like the mount bind option + exclude might be the most elegant option for this case. Just make sure to add the bind mount into your fstab so it comes back after a reboot. :)</div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 8, 2015 at 1:18 PM, Michael Johnson - MJ <span dir="ltr"><<a href="mailto:mj@revmj.com" target="_blank">mj@revmj.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Thought I would chime in here. To the best of my knowledge what you are trying to do cannot be done in a single run. I supposed --fuzzy might work for you but I've never used that option and it sounds scary to me. Perhaps if I spent some time and learned the methodology it uses I would be less concerned. If a feature like this were to be added, it seems like it would make sense to add it as a new "filter" type.<div><br></div><div>But mainly you've piqued my curiosity. The requirement that it be able to happen in a single rsync run seems very odd. Is this just a desire, or is there really something that bad that would happen if you did one pass syncing A to B excluding FolderA and FolderB and then a second pass syncing FolderA to FolderB?</div><div><br></div><div>The most likely scenario I imagine is that you are running this by hand and manually enter the SSH password. Given the process take a long time, you don't want to enter the password again mid stream. If this is the case, you could set up SSH keys to allow this to happen without a manually typed password. You can find how to set that up here:</div><div><a href="http://www.chainsawonatireswing.com/2012/01/15/ssh-into-your-synology-diskstation-with-ssh-keys/" target="_blank">http://www.chainsawonatireswing.com/2012/01/15/ssh-into-your-synology-diskstation-with-ssh-keys/</a><br></div><div><br></div><div>If you don't want to do ssh keys w/o a password, you could use ssh agent with keys.</div><div><br></div><div>Finally you could also utilize ssh multiplexing (it looks like that should work with the synology nass). You can find information about this option here:</div><div><a href="http://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing" target="_blank">http://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing</a><br></div><div><br></div><div>The other (very unlikely) scenario I can imagine is that there is something that prevents you from logging in more than once every X hours/days like a time lock safe. multiplexing would help here as well. But this scenario seems unlikely, it was probably silly to even mention it.</div><div><br></div><div>If there is another case I have not considered I would be very interested to know where this requirement comes from.<br></div><div><br></div><div>Thanks!
