[erlang-questions] Reliable file transfer?

[Lloyd R. Prentice]

Hello,

I’m evaluating https://www.rsync.net/ as a possible backup/archiving service for Erlang dets and Mnesia data.

rsync.net offers replicated data store on ZFS with frequent snapshots at an attractive price. Data can be transferred via rsync, SFTP, etc.

My thought is to create a data management app that would automate the backup/archive/restore functions. But I don’t understand the data transfer options available in Erlang well enough to implement. 

The options I see are:

— calling rsync via os:cmd/1 — seems simple enough but I’m breaking out of Erlang
— ssh-sftp — just don’t understand how to use this library
— File Transfer Service — docs are totally confusing????

One would think that this is an every day plain vanilla kind of problem. But there’s scant guidance on the web.

Can some kind soul point me in the right direction? 

Many thanks,

LRP
