Second attempt at posting this question.

In windows land I use Synology Drive Sync or Onedrive to upload files from my imaging PC as they are captured. This means they are immediately protected and available for analysis/consumption on my processing pc.

On my ASIAir I had to create a robocopy job to copy the files off, but this is somewhat unreliable as the wifi network fluctuates. I would therefore prefer resilient push-type file sync.

Is there any equivilent option available within Stellarmate?

I use SyncThing for stuff like this:

syncthing.net

StellarMate provides Samba share that you can map as a drive in Windows (e.g. Z:/). So perhaps Synology can monitor this network drive and sync it?

I have syncthing up and running, looks promising.
