Thanks for your feedbacks, I appreciate your sfx2000Īt the moment I doubt I'll get a type C to ethernet adapter but I'll keep you posted as soon as I do.Before connecting to your Synology NAS over SSH you'll have to allow SSH connections via NAS' WebUI. CPU usage is pretty intense for a while and even simple actions happens after severals minutes. It is somewhat slow, I am guessing it calculates files' hash comparing both directions. The best compromise I found is in the app Resilio, which can be downloaded for free on various OSes, including Qnap's. On the other hand, one way sync seems to be real time but I haven't done much testing just because I do need it to be two ways. In fact, the new Hybrid Backup Station app doesn't state anything being real time when selecting 2-way sync, something which they were saying on the previous backup app. Oh well, it is real time while being scheduled to happen, so to speak: this 2-ways sync can be done only on a schedule, be it every now and X minutes/hours/days, on a specified time, etc. Gents, I have been able to do some testing: what a disappointment.īasically, RTRR (real time remote replication, as they like to call it) is not really real time. However, it would be amazing if someone, who has experience in RTRR, could answer these questions. I'll need to do my own tests once I get back home. Does the remote NAS replicate the action or does it require transferring files all over uploading them as a 'new' through internet connection? I think the latter happens. A (sync'ed) folder is being moved from SSD to HDD. Scenario: local and remote NAS configured identically with two drives: SSDs in the slots #1 and mechanical HDDs in the slots #2 each drive has a shared folder synced remotely on the other twin NAS.Question number one leads directly to question number two - if only the name of a file (or more files) has changed, is the change reflected in the remote NAS as file name change or does the system consider the file(s) as new file(s) thus requiring transferring over the whole file(s)?.Are the changes being applied 'instantly' to the remote NAS or does it take a while before the system realises which files have changed because of some sort of calculation? In the local NAS, all of the files are renamed in a batch (in Windows, select all files and then hit F2 to rename progressively). How efficient is QTS handling changes to files? Let's suppose both NASes sync'ed a folder with 1000 files.Have you ever heard anything about it? Not necessary at the moment, just curious for had a look at this Qnap page which talks about RTRR sync.Ĭan anybody answer these questions please? I think I found one in Italy so I might just get it while I am here.Īlso, it looks like I can virtually pair two ethernet interfaces aggregating them. Sorry I have been missing for a while but I got super busy with work and unable to put my hands on for some proper far, it's been impossible to get a hold of an Apple USB-C to ethernet adapter: out of stock in London. Whichever solution I use, it shall be as straight forward as possible. The latter can be installed on a NAS as well, but I am not sure how well they work. Reading in online forums, I found these two tiny softwares: Syncthing and Resilio Sync. Synology offers a feature called Cloud Station which could work but I am afraid will be too slow. A workaround could be two folders on the two QNAPs syncing mono-directionally but that isn't really practical. Unfortunately, as I wrote above, it seems there is no way to have a bi-directional syncing between the two. Originally, I thought to buy two QNAPs, one to install in the location A and one to install in the location B. In the location B, there is a computer (MAC or PC), maybe with a local NAS, which needs to access the same data located on the workstation (or on the NAS), either by having a local copy or by opening the files as if it were on a local hard disk (as opposite to the location A, both these features will be used on different times). The data must be accessible through the local network as if it were stored on a DAS, nothing to be copied to the computer themselves (no local sync). By process, I mean open, rename and/or delete pictures, mostly. Data could be stored on a NAS locally as well. These computers will access & process data on one of them, let's call it the main workstation. In the location A, there is a network of PCs connected through a router and a 4G internet connection. So here is the scenario, maybe someone has some ideas. I was thinking to buy a NAS or two, until I found out that there is no such a feature because of the impossibility to track changes to files which could be potentially changed in two different locations at the same exact time: conflicts. I need to find a solution capable of bi-directional syncing.
