I have two TS-216G (QTS 5.2.9.3410 Build 20260214)
and two shared folders synchronised from NAS A to NAS B
NAS A is at the office. NAS B is at home.
I’d like to be able to work from home on NAS B, with the data updating instantly on NAS A while still maintaining the once-daily synchronization from NAS A to NAS B.
I’m wondering if the instant synchronization from NAS B to NAS A might cause a problem with the evening synchronization from NAS A to NAS B (a sort of loop…).
If this solution were to work, what would be the best configuration to set up on NAS B for instant data synchronization with NAS A?
1.) You set up a Two-Way sync in HBS. Just let that run and keep things synchronized between the two NAS units (preferably over a VPN as exposing a NAS to the internet is a bad idea).
2.) Use Hybrid Mount to Mount NAS A on NAS B. This will allow NAS A to show up as a volume on NAS B with commonly used files cached on NAS B.
The other thing to think about is do you really want a sync each day from NAS A to NAS B or do you want a Backup of NAS A to NAS B?
I have mine going to a WebDav drive. But you could set one up between your NAS units. But let me repeat myself from before: NEVER EVER NEVER EVER NEVER EVER expose either of your units to the Internet. So please use a VPN when doing this.
The most efficient, and generally the most secure, is when a VPN is setup directly between the routers, not “inside” your network. There are other
next best" options, running a VPN on a standalone device, but if the routers can handle it, this is likely the best option.
I’m not sure about the app called “SyncThing.” I also am not clear on your ability/knowledge of networks.
QuWan, as I understand it is not a VPN per set but a way to tie in multiple NAS units over the internet. Maybe I am incorrect in this as I don’t use it.
I would set up a real VPN between your two networks. Wireguard and OpenVPN are two of the main VPN protocols. Wireguard has caught on a lot in the past few years as it’s fast and very secure. If your router supports it, great. If not, then you can use an app like Tailscale on the NAS to create the Wireguard connection.
We’ve tested setting up two-way sync between the two NAS units you mentioned, and it should work in principle. However, you’ll need to be careful with the scheduling — make sure the two units aren’t running the sync at the same time, to avoid any unexpected issues.
As for the VPN you mentioned, you might want to consider QHora. Thanks!
Continuous 2-way synchronizing is fine. But you only do it on ONE side. There’s no need to have a second sync job on the second NAS. Set up a SINGLE 2-Way sync job and off you go.
