@Shane Cardwell yup, I did the same, use the realm to upload and locally delete the world, then redownload it. Problem is that this is a temporary fix, as some others have noted. The issue reoccurs eventually. It seems really scummy that the bug is one that Mojang/MS can profit off by not fixing. Hopefully they do fix it, because I really don't want to pay for a realm just to use as backup storage.

@Levi Klopfensteinyeah there's more and more people encountering this issue, it's a problem as Xbox players can't access the cloud storage to even troubleshoot it ourselves. Really hope this picks up traction.

7 year old world, same issue on XBSX. Strangely the size of my world DOUBLED when this started to happen. I am under the same impression this is a more widespread issue, the support ticket I opened and finally responded to indicated they are aware of it and working on a fix… no ETA… yada yada.. check Minecraft news for updates and then closed ticket. Hope I’ll get my world back this sucks! I did download my save like others have said using tools on the Xbox but as we are seeing this workaround appears to be temporary (for now). If someone makes a tool to fix these worlds they can make money probably I would pay someone to fix mine its worth it to me!

My survival world is only about 6 months old, and was kess than 150mb until recently. I didn't notice when, but my suze after syncing shows 280mb now, but the.cloud size is showing as 3.7gb after deleting local saves. My son's small world won't even sync, and is unplayable now.

Exact same has happened to me 3.7gb. I’ve spoken to someone who has done plenty research and he’s said my world is beyond repair

Same issue.. one world that shows with MC world downloader app on xbox sx 3,2GB and last sync like 1month ago. Original world is unplayable - pink/black screen. When I copy this world, remove almost all of addons, I can join the world, but ofcourse same issue with cloud quota with quit&save action..

I should add that at a certain point people are unable to edit or even delete a world because it can no longer be synced, meaning they essentially can't play at all.

I don’t play other games on my Xbox. At least my game is saved locally. I did delete some duplicate worlds from when I was having corruption problems, and that seemed to help for a while, but now the problem is back. I’m not convinced that it’s a cloud space problem, because I recently started a new world, and I had an older world that was much bigger about two years ago. I never had storage problems with that one. I checked out the Microsoft troubleshooting site, and they finally said, talk to Mojang. So here I am! BTW Microsoft gave some horrible advice and some people accidentally deleted worlds they worked on for years. Like my situation (although I didn’t accidentally delete anything, and didn’t follow the advice they suggested to go into the Xbox storage menus) it fixed their problem for a short time, and then they were back at square one. One user said that they deleted everything and started a brand new world, and are getting the same error message. I hope you can fix this soon!

several posts on reddit about this same issue. known issue, support ticket acknowledged but no fix yet or “official' bug confirmation of issue but they know about it.

BTW deleting your worlds in attempt to follow known fixes (at least for me) made it so my game went from unable to save only to unable to play because the game tries to download from the cloud and it fails. So think twice before deleting your worlds. They may still live happily on your Xbox for now. I tried other devices also to restore the world save, no fix.

im having the same issue rn minecraft was having “issues” saving to the cloud so i googled salutions to and i cleared my local saved data restarted my xbox and then this one super old world i have just reffuses to snych i even have a copy of it from a while back that works please mojang fix your game

Apparently Mojang knows about and have for a few years now. I've been having the same problem for a few years and there hasn't been any update on a fix coming. Sometimes it syncs if you delete almost everything from Minecraft, but that isn't an option for most people. It's crazy how a bug this bad has existed for so long. I honestly doubt a fix will ever come.

This may be another problem, but my world had disappeared from my worlds list, and afew ppl said to clear local saved data (on xbox), and the world is back but now every world besides 1 won’t sync to cloud. No idea if there was a different way to fix it without this happening.

I've just encountered this issue myself. It is really annoying, I've encountered it on my other game but only once. it's even more annoying because I tried ignoring it and I just ended up losing like 20hours of gamplay instead on my world. And I've tried to factory reset my xbox already too but it did nothing. I too think it's a xbox problem but I've tried to delete all my game clips too but that didn't work either. I have no idea what it is but I really hope mircrosoft fixes it. Because the fact I still encounter it months after it first came up is crazy.

I forgot to mention that on my other game it fixed once I deleted my game clips. at least for now I'll update in the future

This just started happening after last update.

Thinks the file save us three times the file size.

Hey guys, just saw a preview edition changelog, I think one of the fixes is for this issue! Not sure yet, we'll have to see when the Chase the Skies update drops to see if it applies to bedrock edition itself! Fingers crossed

I just read the patch notes and yes that is 100% the issue that we are all encountering, let's pray this fixes the issue for good.

Yes!!! This is awesome news! Crossing my fingers and updated my Reddit post on r mincraft..

Thank you so much for updating us!

It will be for Bedrock users by the way, the note says its an issue with Xbox cloud storage and Xbox has Bedrock edition, good work guys.

I am at work and won't be able to test it any time soon, but the changelog doesn't seem to indicate any fixes for this or other similar issues (including the issue they referenced in the Beta and Preview edition changelog). Not sure if it's fixed.

Doesn't seem fixed, someone said the preview where it was originally listed was for 1.21.100 whereas what we got today was only 1.21.90, so I'm guessing the follow-up patch or update will include the remaining fixes.

Just confirmed it's not fixed. I haven't played my main world in a long time, last time I played it I had done the Realms temporary fix, so it was syncing, just very slowly (2 mins for cloud sync). I just played for a few minutes, (vibrant visuals look pretty cool!) and left the game. Took about 1 minute to sync, so maybe they switched something up, or it's just that I haven't played in a long time. But still seems to be an issue overall.

Levi Klopfenstein, are you looking at the change log for Minecraft Beta & Preview - 1.21.100.20 ?

”Stability and Performance

• Fixed an issue where Xbox cloud saves would grow excessively in size with each save. (MCPE-197900)” -
  
  We know the cloud sync error is related to the increase in world size (at least for the many people, tickets and reddit posts I have been involved in along with my own interaction with Minecraft support. And looking at issue ticket 197900 thread, the person who raised the initial ticket they are resolving on 1.21.100.20 specifically uploaded a screenshot showing the exact same cloud sync error we have been experiencing. I am assuming this hasn’t been released then it won’t be tested yet by anyone without Beta or Preview privileges to tell us if it is or isn’t working since that version has not been released yet.

G Real yeah I was looking there, I just hoped that the fix would be included in the chase the skies release as well. Looks like we'll have to wait a big longer, but it's encouraging to know that they know it's an issue!

New update 1.21.92 changelog doesn't indicate any fix for this issue.

Having this issue occur on XBOX ONE and XBOX SERIES X. Old worlds that are saved in the cloud are also not accessible because of this now.

New update to fully make Minecraft on series X/S “upgraded”. Just verified the update did NOT fix the issue.

On my Series X, I deleted every save except for my main save I've had for 7 years which is ~850mb. I still get this message when saving after the most recent update.

Still having this issue on Xbox X, none of my large worlds are playable without becoming corrupt.

Issue still persists in Xbox Series X. This all started after an update in mid May. Mojang should make a way to easily export your worlds for backups.

I tried realms, but it gives says “unknown error” once the upload completes.

Small update: I've been in contact with Minecraft support for some time now. The first two thirds of the email chain are just basic troubleshooting advice (all of which I had already tried), but eventually the issue was escalated to Camilla, who recognized the issue and said this,

“Now, it looks like you're actually encountering a known issue which is affecting some players. The development team is currently working on a resolution that should mitigate the issue as soon as possible.”

Whether this is just a cookie cutter response, I cannot tell. I followed up (and had already listed multiple times in previous responses) by asking if she could confirm whether the dev team is aware of this bug report, or if the bug report that @G Real shared above (MCPE-197900) is the same issue, since that one had been resolved on the preview edition.

Fingers crossed!

Got a response already!

Camilla wrote,

“Thank you for getting back to us. I see you were able to find some bug reports regarding this issue - thanks for staying proactive while we shared information about the issue you're facing.

At the time, we cannot confirm that your case is linked to a specific bug in the Minecraft Bug Tracker, as they are best handled by the game developers.

But what we can confirm is that the team is aware and working on improvements, though we don’t have a timeline just yet.”

That is good enough for me, confirmation that at least someone on the dev team is aware of this issue! Thanks Camilla!

Remember guys we still haven't gotten the 1.21.100 update which the original patch note for this issue was listed in. It wont be until later in the year at the earliest.

@Levi Klopfenstein I did open a support ticket back in May and had the same thing happened, it is not unusual that they won't ever confirm anything more they to say something along the lines of ‘they acknowledge, do not have an estimated date or time as to when the fix for the Cloud Sync Failed issue will be released to players. They did assure, however, that the development team is aware of what is occurring and indeed are working on a fix.’ Like @Shane Cardwell mentioned we are waiting for this to be hopefully addressed in 1.21.100 (fingers crossed)

For anyone still scared of the future of your minecraft world, I am happy to inform you that I have a simple fix that will likely make your current world sync to the cloud once again, just like it used it. Not only that, but it will make your world size dramatically lower as well, and you also won’t have to wait for the update to come out either.

Disclaimer: If you can’t even enter your world, this method will NOT work. This method is only for people who have large worlds that only save locally but do not save to the cloud.

1. Buy a realms subscription. You don’t need a credit card or actual money. I used entirely just Microsoft rewards which is free, I saved up enough points, and purchased the $3.99/month realms subscription on xbox (not the $7.99/month one). This may take a few days or weeks to save up enough points, but it’s actually pretty easy to do and it is definitely worth it. You just need to download the Bing mobile app, sign in with your xbox account, and to get points, just click a few buttons and search stuff in the app every day. Eventually, redeem a $5 microsoft gift card when you have enough points. Then on xbox, just purchase the subscription with your free money.

2. Once you have a realms subscription, duplicate your large, only-saved-locally world on your xbox from the worlds menu. Then, go to the Realms tab > Settings and eventually you should find 3 empty worlds in your Realms (labeled ‘New World’). Click on any one of these, then click ‘Edit World’.

3. In the empty realm world’s settings, go all the way down until you see the ‘Replace World’ or ‘Upload World’ button. Click this, and choose your duplicated world from earlier when prompted.

4. Once uploading is successful, you should be happy knowing your world is protected in a seperate cloud now! But we’re not finished yet. So next, download your Realm world, and it will appear in your regular worlds list.

5. This is going to be the scariest part, but I promise, once you do this, your world will be syncing to the cloud again like normal. Go into your original world’s settings (not the duplicated world nor the realm world - I mean the original world that you’re always playing). Delete the world. This is going to be scary and weird, but trust me, I have this massive world for 4 years that I’ve played almost every day, and everything worked out fine for me. If you’re feeling skeptical, do what I did: Upload two versions of your duplicated world to Realms, then upload your original world as well. So this way you have plenty of backups. I also went into the downloaded Realm world to make sure everything was exactly the same as the original. It was, but I encourage you to also do the same, just to be sure before deleting your original world.

6. Rename your downloaded realm world to your old world’s name, because it will have a different name by default.

7. Play the downloaded realm world, and save the game like normal.

8. Your world should likely be saving to the cloud again!!! If not, do not panic - mine didn’t either. You might have to wait a few minutes or even restart minecraft for it to work. But eventually, you should be left with an uncorrupted, much smaller world that syncs to the cloud again like normal. Note that this will definitely not work unless you do step 5 - trust me, I tried.

Note that if anything goes wrong after step 4, don’t worry - your world is always in Realms, so you can just redownload your backup at anytime.

It’s also worth noting that this method will not work if you can’t even play your world. Unfortunately, you will likely have to wait until 1.21.100.20 releases in order to play your world again. But once you can eventually play it again, try the steps mentioned above to make your world much smaller and sync to the cloud again. This is a proven method that works, because my world went from 2.5 GB to 98 MB after doing this. I’m still not sure what causes this issue but it might be that hundreds of corrupted saves accumulate in the cloud and the game lacks any features to clean up the corrupted saves, so eventually the world gets too big and can’t sync anymore. Uploading to realms seems to refresh and clean up everything, then deleting your old problematic world frees up all that space in the cloud.

Additional note: This is the only method that worked for me. For months, I have tried everything I could to fix this problem, and this is the only thing that reliably worked. I truly wish the best for anyone who has this problem. Please give this method a try if you can. Have a great day!

@Robert Hi Robert, that is the most comprehensive and easily followable version of the fix I have seen! Excellent write up. I will note, perhaps anecdotally, that this did not work for me, at least not permanently. It does indeed fix the problem, but only temporarily. The cloud save bug still occurs, and will eventually grow your world’s cloud save size to an unmanageable level, at which point the game begins re-issuing the “local save successful but cloud sync failed due to quota” message. But for someone who wants to use the free trial of realms to get temporary access to their world (until this bug gets fixed), this is a great help!

Hooray!! Looks like 1.21.100 finally fixed this! My world went from taking 2+ minutes to save to 7 seconds! Please comment if your world was in the actual unplayable state, or giving the “cloud sync failed due to quota” message, if it is now working. If so, I'll edit this report as resolved (if I can).

Hooray once again! Great job Mojang

I had 2 of my son’s worlds in the unplayable state (that we were just going to delete) and my main world with the failed due to quota error. The smaller of the unplayable worlds I was able to sync and ultimately delete successfully. The larger would not sync, but I was able to delete it from the main menu by choosing multi select and deleting it. My main world (290gb) still gets the unable to sync due to quota error.

Still not working for me. Still getting the failed cloudsync message. At least my world is still playable. Hoping that, since the game very recently (today) updated on Xbox, that maybe the next time I fire the game up, it’ll save properly.

Feanix and Kamala, that's interesting. Sounds like there are still some issues to iron out. Like I said, my world loads perfectly fine now. I suppose it's possible the upload to realm - delete local copy - redownload world solution May actually be more helpful now, as it can get the world out of that cloud sync error state. I had gone through those steps before, so my world wasn't in the cloud sync error state, but it was taking multiple minutes to save and upload to the cloud, indicating it was still exponentially growing in save size. Now it seems to be working fine.

I updated to 1.21.100 and still have the same issue

Sam wood: the recent version of minecraft is 1.21.101 not 1.21.100

Try update it.

I didnt work for me either. I will try. 1.21.101 but the anticipated 1.21.100 fix did not fix my world loading or the Xbox cloud issue at all. I even deleted the game saves from my Xbox to force the system to download my cloud saves again and got excited when I saw my Xbox running a huge download that took about 10 minutes on a very high speed connection (my game inflated from 1.4 to over 2 GB during this fiasco) but I was finally disappointed by the “Cloud Save Failed” coming up again after all the time spent with Mojang support and the promised fix I waited for.

I can confirm the update has fixed this issue for me. I would have responded sooner but only just started playing again. I believe if you're still having issues then your issue may be a separate one, or possibly a corrupted world.
