For newer games (meaning, in this case, games that are still being actively developed and/or supported by the developer), the devs are usually the ones who implement cloud saving (though I have heard of at least one instance where GOG took care of it before they can!). Terraria has only received a handful of updates in the last year or two, and I honestly don't know if there's even much active development being done on it anymore, so I wouldn't look for full support for Galaxy features until/unless they wind pushing another major content update.

You probably don't need to worry too much about losing saves, though -- the game autosaves periodically by default, and it also creates its own backups in case the main save gets corrupted. Until cloud saving is implemented, if you're really worried, just periodically go to your Terraria folder (default location for the standalone version is C:\Users\[your username]\Documents\My Games\Terraria\, but I think Galaxy puts them somewhere else by default), zip up all the subfolders named after your characters and worlds, and back those archives up to an external drive, or upload them to some cloud service. Once every couple weeks should be sufficient, and even once a month would probably be fine.

For whatever it's worth, I've never experienced savegame corruption with this game. I think I occasionally lost a bit of progress due to the game crashing or hanging, but even that didn't happen a ton...and cloud saving wouldn't help you there, anyway. :)

BTW: You picked a good time to start playing. Enjoy all the cool Halloween costumes and stuff!

Thanks a lot for your reply, which is very helpful. I didn't know that Terraria autosaves by default during gameplay. So I probably don't have to worry too much about a corrupted save file.

I haven't played a sandbox game before and I am surprised how much stuff you can do in this little game. However, Terraria throws you right in at the deep end. I died a lot in the beginning when night fell and the zombies came. Until I realized that I have to build a house for shelter and should go mining at nighttime until I have a better weapon and stronger armour. :)

Thanks again for your help and have a nice day.

I've only experienced save file corruption due to a crash or trying to use a world editor that wasn't udated to handle the version of the game I was playing. In my 1300+ hours of playing (since 1.0) I have heard about a few experiencing frequent save corruption, but those were definitely the exceptions and I expect they were due to hardware failures.

Happy to help. :)

If you have any questions about gameplay, feel free to ask in this subforum, as there are still a few knowledgeable people that check it from time to time. Also, among the various interesting abortive topics here, my old Terraria General Discussion thead has a lot of useful info (some of which is now out of date) and many interesting anecdotes. Spoilers abound, though, and half the fun for a lot of people is figuring things out themselves, so beware! (This goes double for looking stuff up on wikis or watching "tips & tricks" videos: I strongly advise that you only do such things when you're absolutely stuck on how to advance for a few consecutive play sessions, or when you're getting bored with the game -- and even then, a self-imposed "get in, get the crucial info, and get out" rule with regard to the wiki might keep you from accidentally spoiling other things that you probably would've found on your own, once you started progressing again.)

I'll have a look at your Terraria thread at some time in the future. I needed some backup at the start, for the zombies and some kind of weird eye killed me almost instantly. At the moment I just want to explore, dig and craft. - as they say: the journey is the reward. :)

Ah, demon eyes -- the most pressing reason you need to make sure your first shelter has a roof. =D
