Option to save to and load from a savestate file about send

[wallacio]

This is interesting. I've been scratching my head trying to work out how this works, in practice.

I've deployed Send using the provided Docker image. All good, works well. The host has a running Redis instance so rather than pull down another Docker image with redis-server, I'm using the host's instance instead. All good there too.

Now, what I'm wondering is what happens when the host gets a reboot because in my mind, Redis isn't (by default) persistent so I would expect Send to lose any notion of 'state' for links when this happens. I could reconfigure Redis to use RDB but to me, that's kind of going against Redis's transient nature. It also doesn't look like this is how Redis is used with the docker-compose version either, anyway.

I suppose the question is, why not use something like SQLite (just an example) for storing state? Something that's by its nature is persistent on restart/reload?

I appreciate that I could be very wrong in my assumptions. I can't say I'm on board with Docker as a "thing" but for things like this, it is great - there are just a few holes in my understanding...!

Redis is used for this. Please make sure you are running a Redis instance and have it configured correctly.

If Send can't connect to Redis, its 'state' is lost on restart.
