I still remember the cold sweat I felt back in 2021 when my PC crashed mid-exploration, right after I’d finally tracked down a rare S-class exotic ship I’d been hunting for weeks. The first thought that popped into my head was, does No Man’s Sky autosave often enough to save that once-in-a-lifetime find? Spoiler: back then, I didn’t understand how the save system worked, and I lost that ship entirely. After 7 years of playing NMS across three different platforms, I’ve figured out every quirk of the autosave system, and this guide will walk you through everything you need to know to avoid the same frustrating losses I dealt with early on. I’ve tested every trigger, run into every common failure, and picked up dozens of small habits that make losing progress almost impossible now.
How Does No Man’s Sky Autosave Actually Work?
First, let’s clear up the basics: yes, NMS does have an autosave system, but it works very differently from most other open-world games you might have played. It doesn’t run on a set timer, so it won’t save your progress every 5 or 10 minutes no matter what you’re doing. Instead, it only triggers when you complete specific in-game actions, and it stores up to 3 separate recent autosave files alongside your 2 manual save slots for extra safety.
The full list of confirmed autosave triggers includes:
- Exiting your starship: This is the most reliable autosave trigger, and it activates every single time you climb out of your ship on any planet, space station, or freighter, no matter how long you’ve been inside.
- Interacting with a save point or beacon: Even if you don’t select the option to create a manual save, just walking up and activating a save point will trigger an autosave of your current progress.
- Completing a main story mission or major side quest: Big quest milestones, like finishing an Atlas path step or unlocking a new settlement, will automatically save your progress right after the cutscene or reward screen pops up.
- Warping to a new star system: The game will autosave right as you finish the warp animation and load into the new system’s space, before you do any exploring or run into any local pirates.
You might notice that none of these triggers include common activities like on-foot exploration, base building, or extended combat. That’s the biggest gap new players fall into. If you spend 2 hours walking across a toxic planet hunting for rare resources without ever getting back in your ship or placing a save point, there won’t be any autosave of that progress if your game crashes or you lose power suddenly. I’ve seen dozens of new players post about losing entire base builds because they didn’t know autosaves don’t trigger while you’re placing building parts.
Common Autosave Failures You Need to Watch For
Even when you hit a valid autosave trigger, there are a few scenarios where the system can fail or create a corrupted save file that won’t load properly. Most of these are avoidable if you know what to look for, but they’ve cost me hours of progress in the past so I want to flag them clearly.
Long unbroken on-foot exploration is the most common cause of lost progress tied to autosaves. If you’re exploring a cave system, hunting for alien relics, or chasing a rare creature spawn, it’s easy to lose track of time and go hours without hitting a save trigger. I learned that lesson the hard way when I spent 2 and a half hours exploring a massive underground cave system on a frozen planet, hunting for rare activated cobalt. I never got back in my ship or placed a save point the entire time, and when my game froze after a random meteor strike, I lost all 3000 units of cobalt I’d mined, plus the 4 ancient relics I’d found in hidden ruins along the way.
Mod conflicts are another big risk, especially for PC players who use custom building mods or inventory editors. Some mods that alter core game files can block autosave triggers without you noticing, or corrupt save files during the save process. If you notice that your game isn’t creating new autosave files when you exit your ship, disable any recently added mods first to see if that fixes the issue. I’d also recommend making separate manual save backups every week if you play with a heavily modded setup.
Crashes that happen mid-autosave are less common, but they can completely corrupt your most recent save file. If you see the little save icon in the corner of your screen, don’t close the game or turn off your console until it disappears. Interrupting the save process almost always leads to a broken file, and you’ll have to load an earlier save to get back into the game. Multiplayer sessions also have a small quirk: autosaves only track your individual progress, not the group’s, so if the host leaves mid-session, you’ll still keep all progress up to your last autosave even if the group didn’t finish the activity you were working on.
How to Supplement Autosaves to Avoid Lost Progress
Autosaves are a convenient safety net, but they’re not designed to be your only method of saving progress. A few small, easy habits can make losing progress almost impossible, even if you run into crashes or mod conflicts. I do all of these every time I play now, and I haven’t lost more than 10 minutes of progress in over 3 years.
Get in the habit of hopping in and out of your ship every 15-20 minutes when exploring on foot – it takes 2 seconds, and it’s the easiest way to trigger a reliable autosave no matter where you are. I even do this when I’m exploring caves that are a 10-minute walk from my ship; the walk back is worth it to avoid losing hours of work if my game crashes. If you’re too far from your ship, craft a portable save point to bring with you. You unlock them very early in the construction research tree, they only take 10 metal plating and 2 carbon nanotubes to make, and you can plop them down anywhere to trigger an autosave in seconds.
Make a manual save before you do any high-risk activity: like fighting a fleet of 10+ pirates, attempting a difficult settlement defense, spending millions of units on a new ship or upgrade, or starting a long main story mission. Manual saves don’t get overwritten as quickly as autosaves, so even if you die repeatedly or your game crashes mid-activity, you can load right back to the point before you started instead of losing all your progress. I also make a manual save before I log off for the day, just to have an extra backup if something goes wrong with my autosaves before my next play session.
Another small trick: if you’re spending a lot of time building a base, place a permanent save point right next to your build area. Activate it every 10 minutes or so as you’re placing parts, so you don’t lose hours of custom build work if your game crashes. I keep save points right next to all of my major base builds, and it’s saved me from losing half-finished farm layouts and custom base designs at least half a dozen times.
What to Do If Your Autosave Gets Corrupted or Lost
If you load up the game and find your most recent autosave is corrupted or missing, don’t panic right away. There are a few easy fixes that will let you recover most, if not all, of your progress in almost every case. I’ve had to use all of these at one point or another, and they’ve worked for me 9 times out of 10.
First, don’t hit the “continue” button on the main menu, which loads your most recent save automatically. Go to the “load game” screen instead, where you’ll see all of your recent save files, including up to 3 autosaves and 2 manual saves. In almost all cases of corrupted saves, the next most recent save file will work perfectly, and you’ll only lose 10-15 minutes of progress at most. I’ve had my most recent autosave corrupt after a crash multiple times, and the second autosave slot was always intact.
Enable cloud saves on your platform of choice if you haven’t already: Steam, PlayStation, Xbox and Switch all have cloud save support for NMS, and they automatically back up your saves every time you exit the game properly. I had this save me last year when my PC’s hard drive died completely. I lost all my local save files, but my Steam cloud save was only 30 minutes behind my last play session, so I barely lost anything. Just make sure you exit to the main menu before closing the game, so your cloud save has time to update properly.
If you play with mods, keep separate manual backups of your save files every 1-2 weeks. You can find your save files in your game’s install folder on PC, or copy them to a USB drive on console. If a mod update breaks all of your local and cloud saves, you can just load your backup and get right back to playing, with only a few days of progress lost at most. That’s a hassle, but it’s way better than losing hundreds of hours of progress entirely.
At the end of the day, if you were wondering does No Man’s Sky autosave, the answer is yes, but it’s not 100% reliable if you don’t understand how it works. It’s designed to be a convenient backup, not your only method of saving progress, and relying solely on it will almost certainly lead to you losing hours of hard work at some point. A few small habits, like hopping in your ship regularly and making manual saves before big risks, will save you so much frustration down the line. I’ve lost enough progress in my 7 years of playing NMS to know that a few seconds of saving is always worth it, even if it breaks your flow for a minute. Happy exploring, and may your saves always be up to date.
