I've used my Synology NAS for some time now - about two years and counting, and it's been a great tool to backup information locally (e.g. from my phones or shared computers). Then, I got to thinking - it's pretty much a mini-computer. It has a quad-core 1.4Ghz CPU, a whopping 2GB RAM, and _plenty_ of storage. I can do more with it than just use it for occasional data dumps. That is - I could use it for frequent data dumps.
I was working on some data analysis recently, that involved me dealing with data snapshots. These are effectively point-in-time representations of specific data. For example, if you’d be dealing with the amount of items at a warehouse, you could imagine that you’d be taking a snapshot through the day of how many items you have available during each hour. That will give you a pretty good idea of the in-flow and out-flow of materials.
