ZFS Replication to and from remote truenas

[mihaist]

Hello,

This might seem a bit weird but bear with me.
I have 2 TrueNAS instances installed on top of Dell servers. The 2 servers are in different locations that are connected via a site-to-site IPSec tunnel.
Each location has an app that scans 3d models and saves them on a single target, in this case a TrueNAS share. But because the apps can only save on one location, there are 2 sets of data ( folders with jpegs ), one in each location. So, for example, if I were to scan something in location A, when I move to location B I would have to connect to the app on location A to view the scan. The app is inflexible and already talked to the developers, they would not hear me.
I was asked to somehow unify these 2 sets of folders. I was thinking of setting up ZFS replications on both of them for those datasets.
So, let's say the app in location A writes data, and the app in location B writes data, a snapshot is made on A, the replication starts and B receives all new A files. Similarly, after this is completed the direction changes and A receives all new B files.
I am not interested in real time replication, but if I could aggregate the data every 30 minutes that would be a win.

Can something like this be possible and also be sort of reliable?
Pros and Cons for this implementation?

Any advice would be highly appreciated.

Thanks

Replication isn't your method here.

You will need to carefully think out a plan to have 2 rsync jobs which will take new files on either side and move them over A -> B and B -> A.

If you get the switches right with rsync and the app on both sides is set not to use the same file naming standard (to avoid file name collisions for different actual content), you can probably get to what you're describing.

Can the app view files in a different location to where it saves them?

Thank you, it seems that this approach is closer to what i need.

I don't think so, it is pretty inflexible. What did you have in mind?
