shwouchk Posted January 8, 2017 Report Share Posted January 8, 2017 Hello, If I set up the sync to en external HDD on one of the computers, and then disconnect it at some point, will the app detect it as though I "deleted" the files and erase them on the other end, or will it see that the device is missing and act as though it is "not connected"? Thanks in advance for the answers! Quote Link to comment Share on other sites More sharing options...
Moe Posted January 8, 2017 Report Share Posted January 8, 2017 It won't delete your files on other peers connected to that share. Sync will show that the folder is not available and will continue syncing once you have re-attached the external HDD to your computer.

dylan Posted January 13, 2017 Report Share Posted January 13, 2017 I have a follow up question to this as a friend has a bit of a weird workflow that I want to help him with: He has a macbook he carries around with him and two usb hdds that he doesn't carry around with him - one he has at home and one he has at the studio. He wants both these USB hdds synchronized via Sync with a Synology NAS server switched on permanently to help do the relaying (it has the latest Sync package installed and is all set up). So the problem is does sync store its state information in the .sync folder relative to the tree it is sharing or is it stored in some central location on the macbook. If it is some central location then how can I get the above set up to work? (the problem being that if it's central, rather than synching when he plugs in his home HDD it will think files have been deleted and reflect that to the NAS).

Helen Posted January 13, 2017 Report Share Posted January 13, 2017 the answer is: Sync stores the folder tree in 'the central location on mac'. In it's storage - ~/Library/Application Support/Resilio Sync. See details about storage here. So yes, feeding two HDDs with two different sets of files (but same root folder path that for Sync appears as the same sync share) to same Sync instance is not a good idea: Sync will just think that files have change and propagate these changes to other peers. 10 hours ago, dylan said: it has the latest Sync package installed and is all set up) I'd rather double check that. If your friend looks at Package Center, he doesn't have the latest. Take the latest from here Quote Link to comment Share on other sites More sharing options...
dylan Posted January 13, 2017 Report Share Posted January 13, 2017 yes, we grabbed it from that page and installed manually (cedarview was the version we needed). So what's the solution in the above situation? How can he have a HDD at home and a HDD in his studio and use the same mac, and have both hdds sync'd up via the man-in-the-middle NAS?

Well, a standard Sync flow: add a folder from HDD1 to Sync on NAS, share it with the other Sync, on Mac, and pick the folder from HDD2 as destination on Mac Quote Link to comment Share on other sites More sharing options...
shwouchk Posted January 14, 2017 Author Report Share Posted January 14, 2017 I think that the crucial part is to give a unique name to the HDDs so that they don't get mounted onto the same directory (i.e. /Volumes/<name>). I would suggest to use something semi-random so that there won't be a chance that an HDD you attach will have the same name. Quote Link to comment Share on other sites More sharing options...
dylan Posted January 16, 2017 Report Share Posted January 16, 2017 Sync won't let me add two shares with the same key. ie. within the same Sync setting we need to sync HDD1 when it is connected and HDD2 when it is connected but I can't add both into the list, it gives me an error "folder already exists".

Helen Posted January 16, 2017 Report Share Posted January 16, 2017 That is why I suggested connect HDD1 to Sync on Syno and HDD2 - to Sync on Mac. You cannot sync two folders located (attached) to same computer with same Sync instance. Sync sync files across devices. Quote Link to comment Share on other sites More sharing options...
dylan Posted January 17, 2017 Report Share Posted January 17, 2017 yes, that unfortunately means he has to lug around the HDD as he needs the storage to be fast. However it seems that this is the only solution right now so what we'll do is simply set him up to access the Syno sync'd folder as a shared folder on a LAN. The thing is with USB HDDs nowadays they tend to be powered or bigger RAID style setups like a DROBO and the PC/Mac itself is the portable element moving between them. It feels like Sync could address this pattern/workflow well with a few tweaks. Quote Link to comment Share on other sites More sharing options...
dylan Posted January 19, 2017 Report Share Posted January 19, 2017 I'm hitting problems with the synology version of sync locking/tying up my synology (412) performance-wise, it seems to just hog the thing when it is synching a large directory and everything gets very unresponsive.
