The three storefronts differ far less in how reliably they sync a save than in what you are left holding if you stop using them, and that is the comparison worth making. Steam offers the most granular controls and the largest set of games that support cloud saves. GOG Galaxy syncs competently and pairs it with something neither competitor offers: DRM-free offline installers that keep working with no account, no client and no company. The Epic Games Store sits between them technically and behind them on user control, exposing far fewer switches when a sync goes wrong.
None of the three protects everything, because all three sync only the files a developer registered with the platform. This article covers how each implementation behaves, what their DRM positions mean in practice, and what happens to both your saves and your library on the day you walk away from a platform.

Top 3 picks at a glance
Short answer
Use Steam’s controls if you play across two machines, because being able to disable sync per game and choose a version during a conflict is the difference between recovering and losing a session. Choose GOG when long-term access matters more than convenience, since an archived offline installer plus a local save is the only combination that survives a platform disappearing. Treat Epic Games Store cloud saves as a convenience feature you should not lean on for anything irreplaceable. Whichever you use, keep your own copy: the platform protects you against a dead drive, not against a bad save.
| Platform | When it fits | Trade-off |
|---|---|---|
| Steam | Multi-PC play and the widest cloud save support | Library access depends entirely on the account and client |
| GOG and GOG Galaxy | Long-term ownership, offline installs, archiving | Cloud features require Galaxy; catalogue is smaller |
| Epic Games Store | Free titles and exclusives you play casually | Fewest user controls when sync misbehaves |
| All three plus a local archive | Anyone with a long playthrough they care about | Ten minutes a week of maintenance |
How each platform implements cloud saves
Steam uses two mechanisms. In one, the developer declares the folders and file patterns that should be synced, and the client handles them without the game knowing. In the other, the game calls Steam’s storage functions directly and decides for itself what to write. From your side both look identical, but the first is more likely to pick up loose configuration files while the second is tightly limited to what the developer chose.
Steam also gives the most user control of the three. There is a master switch for cloud synchronisation in the client’s settings, and a separate switch on each game’s properties page, so you can disable syncing for a single problem title without turning it off everywhere. When the local and remote copies disagree, the client stops and asks which one to use rather than picking silently.
GOG Galaxy takes a similar approach with per-title control and a view of how much cloud storage each game is using. Support is opt-in per game, so a title in your GOG library may have no cloud save integration at all even when the same game supports it elsewhere. Because GOG’s games are DRM-free, it is also entirely possible to install and play without Galaxy running, in which case nothing syncs and you are back to manual backups.
The Epic Games Store implements cloud saves as a per-title developer feature, flagged on the store listing. It syncs on launch and exit like the others, but the launcher exposes fewer user-facing controls than Steam does, which matters most in exactly the situation where you want them: when a sync has gone wrong and you want to stop it before it overwrites something. Third-party clients such as Heroic Launcher can manage Epic and GOG libraries and offer their own save sync handling, though support varies by store and by version.
DRM philosophy and what you actually own
These platforms hold genuinely different positions, and the differences are not marketing. GOG’s entire premise is DRM-free distribution: every title comes with standalone offline installers you can download and keep, and those installers do not check in with anything when they run. That is the strongest ownership position available on PC, and it is the reason GOG remains the archivist’s storefront despite a smaller catalogue.
Steam’s position is mixed by design. Its DRM wrapper is optional and many publishers skip it, so a fair number of games in a Steam library will run from their folder without the client. Others use the wrapper, or add a third-party protection layer on top. Either way the client is the normal route for installing and updating, and there is no supported way to keep a standalone installer, so in practice the account is the licence.
The Epic Games Store does not offer offline installers either, and its library is bound to the account and launcher in the same way. Some titles will run directly from their installed folder, but that is a property of how the publisher shipped the game rather than a promise the store makes to you.
This shapes how you should think about cloud saves. On GOG, saves and installers together form a package you can genuinely keep. On Steam and Epic, the save is the only part you can hold in your hand, which raises the value of extracting and archiving it yourself.
What happens to your saves and library if you stop
Start with the good news, which is identical across all three: local save files are ordinary files on your drive. Whatever the platform does, whatever happens to your account, those files sit in your user profile or the game’s folder and can be copied to a drive or a cloud folder at any time. Nobody deletes them when a subscription lapses or a client is uninstalled.
Library access is where the platforms diverge sharply. If you stop using Steam, or lose access to the account, you lose the ability to install and update those games. Existing installations may keep running for a while, offline mode helps if it was configured before you lost access, and none of that is a plan. The same reasoning applies to the Epic Games Store, where the launcher is the only distribution channel.
GOG is the exception, and only if you did the work in advance. Offline installers you have already downloaded remain functional forever, because there is nothing to check. Installers you have not downloaded are still behind an account, so the archivist’s habit of pulling down installers for anything you care about is what actually converts GOG’s policy into protection.
There is a second, quieter risk in all three cases: platform-side cloud saves are deleted or become unreachable along with the account. If your only copy of a 90-hour playthrough is in a storefront’s cloud, then the storefront’s terms, not your intentions, decide how long it lasts. Pulling those files out and storing them yourself, as our guide on backing up game saves describes, is what makes the question academic.
Conflicts, two PCs and offline play
Nearly every reported case of cloud saves eating progress traces back to one of two patterns, and both involve a second machine or an offline session. The first pattern: you play on a laptop, close the lid without quitting the game cleanly, and the client never finishes uploading. Later you play on the desktop, the cloud copy is the older one, and the laptop’s progress is quietly replaced on the next sync.
The second pattern: you play offline, deliberately or because the connection dropped. The client cannot compare timestamps against a server it cannot reach, so it makes its decision later, and the heuristic it applies does not know that your local file represents three hours of work. Steam’s conflict prompt is the best defence available here precisely because it refuses to guess.
The habits that prevent both are small. Quit the game to the desktop rather than closing the window, wait for the client’s sync indicator to settle before shutting down, and treat one machine as the primary for any long playthrough. If you routinely swap between two systems at the same desk, sharing peripherals through one of the devices in our roundup of KVM switches for gamers at least removes the temptation to have both running the same game at once.
Power interruption deserves a mention here too, because it produces the nastiest version of the problem: a save that is half-written locally and then synced upward in that state. Clean shutdown is a data-integrity measure, which is part of why our notes on picking a UPS for a gaming PC treat runtime as a means to close things properly rather than to keep playing.
Quotas, mods and what never syncs anywhere
All three platforms cap how much a game may store, and the caps are set for save data rather than for archives. Figures are usually in megabytes per title, which is generous for a list of coordinates and inventory contents and useless for anything else. A game that writes large state files can exceed its allowance and simply stop syncing, often with no visible warning beyond a stalled indicator.
Mods are outside the system on every platform. Mod files, load orders, mod manager profiles and locally generated patches are not part of what a developer registers for cloud storage, so a synced save restored onto a clean machine can load into a world missing half its content. For a heavily modded game, the mod setup is arguably more valuable than the save file itself.
Configuration files land in the same gap more often than people expect. Graphics presets, key bindings, sensitivity values and accessibility options frequently live beside the save rather than inside it, and only the file the developer named gets copied. This is why a game restored from the cloud on a new PC so often plays correctly but feels wrong.
One more surprise worth knowing: running Windows games on Linux through Proton relocates everything into a per-game compatibility prefix rather than your native home directory. Cloud saves still function, but if you go looking for the files manually, they are not where a Windows guide says they will be.
How this comparison is verified
Owen Pritchard, our technical guides editor with twelve years of experience, keeps a diagnostics bench with POST cards, spare parts for swap-testing and multiple OS images, and the multiple images are what make this particular comparison testable. Claims about cloud saves are easy to check on the machine that created them and much harder to check honestly.
The procedure is to install the same game from each storefront on a clean image, play far enough to produce a save, then sign in on a second image and see what arrives. That exposes which files travel and which do not, whether configuration survives, and how each client behaves when the two copies disagree. Deliberately playing one image offline and then reconnecting reproduces the overwrite scenario in a controlled way instead of on someone’s real playthrough.
Behaviour that depends on platform policy, rather than on software, is taken from each platform’s own documentation, since those rules change on their schedule and not ours. That is also why this article names no storage quotas in figures and no menu paths: the numbers are per-title developer settings, and clients get redesigned. If you are moving a whole library to a new drive rather than a new account, that is a different job, handled by the utilities in our roundup of SSD cloning tools.
Making your saves portable across all three
- Turn cloud sync on everywhere it exists, then list the games in your libraries that do not support it. That list is the one that needs manual attention, and it is usually shorter than people fear.
- Pick one machine as primary for each long playthrough, and stick to it. Most conflict damage happens because two machines were treated as equals.
- Before switching machines, quit to the desktop and wait for the client’s sync activity to finish. Closing a laptop lid is the single most common cause of a lost session.
- If you intend to play offline, disable cloud sync for that title first where the client allows it, then reconcile the files yourself when you reconnect.
- Run a save manager weekly across all three libraries so you hold dated copies independent of any storefront. This also captures the mods and configuration files none of them sync.
- Download the offline installers for GOG titles you care about and store them alongside those archives. This is the step that converts DRM-free from a principle into an actual safety net.
- Test one restore onto a different machine or a fresh install. A backup you have never restored is an assumption.
When this comparison does not matter
If you play on one PC, buy from one storefront and never go offline, the differences described here will not reach you. Cloud saves in that scenario are a convenience against drive failure, and any of the three will do the job. The comparison starts to matter the moment a second machine, an offline session or a decade-long timeline enters the picture.
Games with publisher launchers sit outside the comparison too. Titles that run their own account layer on top of the storefront generally handle saves through that publisher’s own cloud, so where you bought the game becomes irrelevant to how progress is stored. Check the publisher’s account, not the storefront, when those games misbehave.
Online and live-service games are the clearest exclusion. When your character exists on the publisher’s servers, there is no local save to sync, no conflict to resolve, and nothing to archive. Account security is the entire backup strategy, and no storefront comparison changes that.
Finally, games with no cloud support on any platform are unaffected by all of this. Older titles, small releases and anything predating these systems keep progress locally and only locally, which puts them in the same category as emulator saves: covered by your own routine or not covered at all.
Troubleshooting
Symptom: a conflict prompt appears every time you launch a particular game. Usually the game rewrites a tracked file on exit, or the two machines disagree about the time. Confirm both systems are synchronised to an internet time source, then pick one machine as authoritative for the session and consistently choose its version until the prompt settles.
Symptom: progress vanished after an offline session. The client resolved the mismatch against you. Before launching the game again, look for the local save files on the machine that did the offline session, since the older file often still exists on disk even though the client considers the cloud version current. Copy it out first, then disable sync for that title, restore, and re-enable.
Symptom: the sync indicator never completes. The tracked folder probably exceeds the game’s storage allowance, most often because screenshots, video captures or mod output landed inside it. Move those files elsewhere and let the client try again before assuming a server problem.
Symptom: the save from your Epic copy does not appear in your Steam copy of the same game. That is expected, because each storefront keeps its own cloud namespace. Many games nonetheless write to the same local folder in your user profile, so copying the files across by hand works more often than not. Close both clients first so neither uploads mid-copy.
Symptom: cloud sync re-enables itself for a game you switched off. Check the client-wide setting as well as the per-game one. A master switch turned back on, or a fresh install of the client with default settings, restores syncing everywhere regardless of individual choices you made earlier.
Symptom: on Linux, the save files are not where every guide says they should be. Windows games running through Proton store their data inside a per-game compatibility prefix rather than your home directory. Look inside the compatibility data area for that specific title, and point any backup tool at that location instead of the native path.
Frequently asked questions
Which platform has the best cloud saves, Epic, GOG or Steam?
Steam gives you the most control, with a global switch, a per-game switch and a conflict prompt that lets you choose which version to keep. GOG Galaxy is close behind and pairs cloud saves with DRM-free installers, which matters more for long-term access. The Epic Games Store syncs reliably for supported titles but exposes fewer user-facing controls, so you have less say when something goes wrong.
What happens to my games and saves if I stop using a storefront?
Local save files stay on your drive in all three cases and can be copied out at any time. Library access is the difference. Steam and Epic Games Store both require the account and client for installing and updating, so losing account access means losing the library. GOG sells DRM-free offline installers, and any installer you have already downloaded keeps working indefinitely without GOG existing.
Do cloud saves carry over if I buy the same game on a different store?
Not through the cloud. Each storefront keeps its own save namespace, so the Steam copy and the Epic copy of the same game do not share cloud data. Local files sometimes do overlap, because many games write to the same folder in your user profile regardless of where they were bought, which means copying the save across manually often works even when automatic syncing does not.
Are GOG games really playable without the launcher?
Yes. GOG distributes standalone offline installers with no DRM check, and games installed that way run without GOG Galaxy present. The trade-off is that cloud saves, achievements and automatic updates are Galaxy features, so a purely offline installation is on its own for backups. The practical approach is to use Galaxy day to day and archive the offline installers separately as a long-term insurance policy.
Why did my save get overwritten after playing on a second PC?
Almost always because one machine played offline and synced afterwards. The client had no way to know your older-looking file was actually the newer session, so it resolved the mismatch the wrong way. Quit properly and wait for the sync indicator to finish before switching machines, and if you must play offline, disable cloud sync for that title first and reconcile the files by hand.
