As the title suggests. I have 2 unraid servers at 2 different locations. 
I'd like to backup from one server to the other. I use cloudflare application tunnels for remote access.
I have already paid for a 5 year subscription for Duplicacy, but I'm open to other options too.
How would one set this up?

I'm not sure if this will help or not but this is what I've done.

• Let's say that we have two servers and on each server there's a share/folder called "documents".  Use syncthing to synchronize the files in the "documents" folder.  Any changes on one server would be synchronized to the other.
• Then, using Duplicacy, set up an archive somewhere on one of the servers and tell Duplicacy to back up the "documents" folder to that archive.

I use Vorta/Borg and it runs each day taking a snapshot each day.  If there are no changes then the archive remains the same size.  If I move some files around in the folder that is being archived then the archive stays the same size because the file contents haven't changed but the archive records the change of location.  The daily snapshot gives me a history of file movements if I need to track that.  If a file was deleted or changed unexpectedly then I can recover it at any point.

 

This setup solves the following problems or provides these features:

• Off-site backup.
  • If any server goes down you can recover from the other server.
• Multiple synchronized file servers.
• Backup archive:
  • Incremental recovery.
  • File change history.
  • Efficiency from deduplication.
