Firebase back-up - firebase

I use Firebase for an Android project and I have some data into a database. I want to know if there is any possibility to save/make a back up to the structure of data. I ask this because somehow, I deleted the project and I had to do all again.

If you just deleted your project, you may still be able to restore it from the Resources pending deletion page in the Google Cloud Platform console with the process shown here.
If that doesn't work, reach out to Firebase support to see if they can help you recover it.
Note that both of these are dependent on the time that has passed since you deleted the project, so time is of the essence.

How can I delete the crash logs from Crashlytics?

Is there a way in Google Cloud Platform to delete all the crashlytics logs that are present? I did some testing and now would like to delete them.
Thanks
This is not possible, however if you write in to Firebase Support, they can delete all of your crash logs associated with a particular build.

Firebase storage: should I delete artifacts files in my firebase storage?

I have understood that each time i deploy a firebase cloud function, firebase automatically save some data in firebase storage. I would like to know excatly which data is saved and if it is safe to delete, or any suggestion on what to deleate.
I have a small project with 200MB of cloud storage used for user data and 10 cloud functions doing a variety of task. At the begining of October, I did few firebase deploy action and now I see a whooping 900MB of us.artifacts data. See below the screeneshot from firebase and google cloud. It looks like I have 256 items there with a mysterious .dms extension (disk image) and I really do not understand what this exaclty is, if i need to keep it or not.
I am currently considering to remove all these file and run a fresh firebase deploy but not sure if this is going to create any problem
Many thanks to anyone who can shine a bit of light here?
As suggested in the comments, you can remove the files and that would not cause any issues.

Firebase storage artifacts is huge and keeps increasing

I've just noticed that my app's storage started to increase significantly.
After having a closer look, it appeared that this was caused by the "artifacts" bucket.
I can see that the "artifacts" storage keeps increasing by about ~800Mb every week which worries me to say the least.
I assume this is related to firestore functions deploys (or not?), but is this really expected? Can I cleanup this artifacts safely?
Appreciate any suggestions on how to safely handle storage size in this case and to keep its consumption at minimum.
Figured out a solution - it appeared there is a way to setup an auto deletion rule in google cloud console for those images that clutter the storage.
go to the google cloud console, select your project -> storage -> browser https://console.cloud.google.com/storage/browser
Select the "artifacts" bucket
Under the "lifecycle" tab add a rule to auto delete old images (in my case I put "delete after 1 day since update" which works fine for me)
Storage is safe now!
NOTE: if you face any deployment issues later, like if you deploy several days in a row and if it gives you an error on deploy, just delete the whole "container" folder manually in the artifacts which should solve it and then redeploy again. (make sure not to delete the artifacts bucket itself!)
Hope the firebase team will improve that - the current behavior looks confusing as it easily leads to an unexpected bill unless you take extra steps to prevent that. But you'll never know that it will happen until it does.
I assume this is related to firestore functions deploys (or not?), but is this really expected?
Yes, it's expected. Every time you deploy functions, Cloud Build will use a dedicated Cloud Storage space for the built docker image, and retain it until you delete it.
Can I cleanup this artifacts safely?
Yes, but then you won't be able to easily revert to a prior image. You would have to deploy again from your own source code.
On top of the GCP's Life Cycle settings for artifacts images, you can also consider the following for further optimization and costs reduction of your Firebase Functions deployment:
Clean up your functions folder, don't put unnecessary files in it, as we do not know if Google will only upload files by dependencies or by the whole functions folder. Feel free to refine this item if anyone of you can confirm this.
Remove unnecessary dependencies from functions/package.json, functions/node_modules and require statements from your JS files, e.g. functions/index.js.
Compact and compress your function's JS files by removing unnecessary comments, console loggings etc. You can achieve this with the help of grunt and uglify NPM packages. Again, we're not sure if the Cloud Build (or any of the Google functions deployment system) will auto-compress the function's images for us before storing them into the Container Registry or Cloud Storage (please refine this item if you have better answer).
Organize your functions properly by creating relevant function groups so that you can deploy only certain group(s) of function rather than simply firebase deploy --only functions.
If necessary, write codes that automatically detect and resolve environmental differences, e.g. environment variables from local emulators to production/staging, because the Firebase emulators and production environments may not be 100% consistent. If you don't do that, you may end up needing to deploy several times per day due to certain negligence -- this will spike up your deployment cost.
If necessary, change your deployment plan: from daily to weekly, or even from weekly to monthly, depending on your monthly budgets, criticality, and urgency.
Lastly, I hope the community can also help to add more recommended costs reduction plans and strategies on this post in order to help some small businesses and individuals to survive better on Firebase and Google Cloud Platform as a whole. Even just some links to good articles would help. Thanks!

AWS Amplify: Resource is not in the state stackUpdateComplete

I'm setting up aws-amplify to my project. I am facing a problem in amplify push when I configured for the first time it worked fine. now i changed the repository since i had to do sub-tree from the old repo.
Now when i do amplify push i get
Resource is not in the state stackUpdateComplete
⠸ Updating resources in the cloud. This may take a few minutes...Error updating cloudformation stack
⠸ Updating resources in the cloud. This may take a few minutes...
Following resources failed
✖ An error occurred when pushing the resources to the cloud
Resource is not in the state stackUpdateComplete
An error occured during the push operation: Resource is not in the state stackUpdateComplete
Just to give some background about this error - what does Resource is not in the state stackUpdateComplete actually mean?
Well basically Amplify is telling you that one of the stacks in your app did not deploy correctly, but it doesn't know why (which is remarkably unhelpful, but in fairness it's deploying a lot of potentially complex resources).
This can make diagnosing and fixing the issue really problematic, so I've compiled this kind of mental checklist that I go through to fix it. Each of the techniques will work some of the time, but I don't think there are any that will work all of the time. This list is not intended to help you diagnose what causes this issue, it's literally just designed to get you back up and running.
The fast options (will solve most problems)
Try running amplify push --iterative-rollback. It's supposed to roll your environment back to the last successful deployment, but tbh it rarely works.
Try running amplify push --force. Although counter-intuitive, this is actually a rollback method. It basically does what you think --iterative-rollback will do, but works more frequently.
In the AWS console, go to the deployment bucket for your environment (the bucket will be named amplify-${project_name}-${environment_name}-${some_random_numbers}-deployment). If there is a file called deployment-state.json, delete it and try amplify push again from the CLI.
If you are working in a team of more than one developer, or have your environment in several different repos locally, or across multiple different machines, your amplify/team-provider-info.json file might be out of sync. Usually this is caused by the environment variable(s) in an Amplify Lambda function being set in one of the files but not in another. The resolution will depend on how out of sync these files are, but you can normally just copy the contents of the last working team-provider-info.json file across to the other repo (from where the deployment is failing) and run the deployment again. However, if you've got multiple devs/machines/repos, you might be better off diffing the files and checking where the differences are.
The slow option (production-friendly)
Hopefully you haven't got this far, but at this point I'd recommend you open a ticket in the amplify-cli GitHub with as much info as you can. They tend to respond in 1-2 working days.
If you're pre-production, or you're having issues with a non-production environment, you could also try cloning the backend environment in the Amplify console, and seeing if you can get the stack working from there. If so, then you can push the fixed deployment back to the previous env (if you want to) using amplify env checkout ${your_old_env_name} and then amplify push.
The complex option (solves more intricate problems with your stack)
If none of the above work (or you don't have time to wait for a response on a GitHub issue), head over to CloudFormation in the AWS console and search for the part of your stack that is erroring. There's a few different ways to do this:
Check the CLI output for your last push and find the item whose status is something other than UPDATE_COMPLETE. You can copy the name of the stack and search for it in CloudFormation.
Search CloudFormation for your environment name, click on any of the resulting stacks, click the link under Parent stack, repeat until you find a stack with no parent. You are now in the root stack of your deployment, there are two ways to find your erroring stack from here:
Click on the Resources tab and find one with something red in the status column. Select the stack from this row.
Click on the Events tab and find one with something red in the status column. Select the stack from this row.
Once you've found the broken stack, click the Stack actions button and select Detect drift from the dropdown menu.
Click the Stack actions button again and select View drift results from the dropdown menu.
In the Resource drift results page, you'll see a list of resources in the stack. If any of them show DRIFTED in the Drift status column, select the radio button to the left of that item and then click the View drift details button. The drift details will be displayed side by side, git-style, on the next page. You can also click the checkbox(es) in the list above to highlight the drift change(s). Keep the current page open, you'll need it later.
Fixing the drift will depend on what it is - it's usually something in an IAM policy that's changed, you can fix this directly in the console. Sometimes it's a missing environment variable on a Lambda function, which you're better off fixing in the CLI (in which case you would need to run amplify push again and wait for the build to complete in order for the fix to be deployed to your environment).
Once you've fixed the drift, you can click the orange Detect stack drift button at the top of the page and it will update. Hopefully you've solved the problem.
GraphQL bonus round (completely bananas DDB drift)
Another fun thing that Amplify does from time-to-time is to (seemingly spontaneously) change the server-side encryption setting on the definition of some or all of your DynamoDB tables without you even touching it. This is by far and away the most bizarre Amplify error I've encountered (and that's saying something)!
I have a sort-of fix for this, which is to open amplify/backend/api/${your_api_name}/parameters.json and change the DynamoDBEnableServerSideEncryption setting from false to true, save it, then run amplify push. This will fail. But it's fine, because then you just reverse the change (set it back to false), save it, push again and voila! I still cannot for the life of me understand how or why this happens.
I said it's a sort-of fix, and that's because you'll still see drift for the stacks that deploy the affected tables in CloudFormation. This goes away after a while. Again, I have no idea how or why.
The nuclear option (DO NOT USE IN PRODUCTION)
Obviously this one comes with a huge disclaimer: don't do this in production. If working with any kind of DB, you will lose the data.
You can make backups of everything and then start to remove the problematic resources one at a time, with an amplify push in between each one, until the stack build successfully. Once it's built, you can start adding your resources back in.
Hopefully this helps someone, please feel free to suggest edits or other solutions.
This worked for me:
$ amplify update auth
Choose the option “Yes, use default configuration” (uses the Cognito Identitypool).
Then:
$ amplify push
Another reason can be this
The issue is tied to the selection of this option - Select the authentication/authorization services that you want to use: User Sign-Up & Sign-In only (Best used with a cloud API only) which creates just the UserPool and not the IdentityPool which the rootstack is looking for. It's a bug and we'll fix that.
To unblock, for just the first question, you could select - ❯ User
Sign-Up, Sign-In, connected with AWS IAM controls (Enables per-user
Storage features for images or other content, Analytics, and more)
which would create a user pool as well as as the identity pool and
then choose any of the other configurations that you've mentioned
above.
I debugged my AWS Amplify CLI push error by doing the following:
Open CloudFormation
Find parent stack with name such as: amplify-companyName-envName-123456
Click Events tab
Scroll down until you find UPDATE_FAILED, which should give you a detailed description of why it failed. e.g. The following resource(s) failed to create: ...
Alternatively (to find parent stack):
Navigate to environment in AWS Amplify site, Overview tab
Click View in CloudFormation
Under Stack info tab, click link for Parent stack
On the parent page, click Events tab
You can try as below
First do
amplify env checkout {environment} and then
amplify push
The solution is:
a. Go to the s3 bucket containing project settings.
b. locate deployment-state.json file in root folder and delete it.
c. amplify push
I got this after making some modifications to my GraphQL schema. I adjusted the way I was making #connection directives on a few tables. I was able to fix this by following these steps:-
Make a backup copy of your new schema that you're trying to push
Run amplify pull to restore your local to be in sync with your backend in the cloud.
Once that completes, you should have the local synced to the cloud and amplify push should work without flaws because it is synced to the cloud and there should be no updates.
Copy over the new schema onto the pulled schema and try running the amplify push once more to see if it works.
If it doesn't work, undo the overwrite to the pulled schema and compare what is different between the pulled schema and the updated schema that you backed up. Do a line by line diffcheck and see what has changed and try to push the changes one by one to see where it is failing. I think it is wiser to not push too many changes to the schema at once. Do it one by one so that you can troubleshoot more easily. If you do have other issues, then it should be unrelated to the one highlighted in this question, because the pulling should solve this particular issue.
In my case the issue was due to multiple #connections referring to GSI, which were not getting removed and added correctly when I do the amplify push api.
I was able to resolve this by amplify pull then, comment off the #connection then the GSI linked to connection then, add each new changes manually, but there was trouble in GSI getting linked again because the local update considered the GSI already removed but in cloud it seems to be retained, and I got error that a GSI is being added which was already in cloud. So I renamed the model name, so it got recreated to new tables in dynamoDB then I reverted it back to the correct name. This is ideal for dev environment which has no much impact.
But of course it ate up most of my time, but it did fix my issue.
In my case it was an issue when switching between amplify env (checkout), the error was not clear but this is what I did to fix it without having to "clear" api and lose the whole database :
Delete the existing API Key by setting the "CreateAPIKey" to "0" in the "amplify/backend/api//parameters.json" then save file and execute "amplify push".
once done, do the same process with "CreateAPIKey" to "1" then "amplify push".
This fixed my issue.
This worked for me
amplify remove storage
And, then
amplify add storage
Then, again
amplify push
As after amplify add storage I mistakenly choose Y to Do you want to add a Lambda Trigger for your S3 Bucket?
I didn't have any Lamda function and also I didn't have anything in my bucket.
In my opinion, these kind of problems always related to 3rd party auth.
Amplify update auth,
then update auth flow the id and secret of 3rd party.
Then push.
It will fix the problem
It's look like a conflict between backend and local
The only thing that work for me is backing up the local schema and initiating the amplify pulling command.
Then use the back up schema file and initial the amplify push.
In most of case updates in the following file must be set manually (for Android):
app/src/main/res/raw/amplifyconfiguration.json
As mentioned by others in this thread - the issue comes from one of the resources that you updated locally.
Check which ones did you modify:
$ amplify status
Then remove and add it again, followed by push. The Api is known not to work with updates right now, so you must remove it if you've changed it locally:
$ amplify api remove YourAPIName
$ amplify api add
$ amplify push

Restore database in Firebase

If I deleted my app on Firebase, then after a week I want to restore it, is that possible? I understand that there is a note that it will be permanently deleted after confirming.. Thanks!
Firebase keeps backups of the data in your Realtime Database. If you accidentally delete data from your database, you can reach out to Firebase support and ask for the data to be restored.
You can also check out Announcing Automated Daily Backups for the Firebase Database
If you delete your project, dont worry. You have 30 days for recovery in Google Cloud Platform. Then you will receive a email with a link for this.
https://console.developers.google.com/cloud-resource-manager?pendingDeletion=true&organizationId= some ID
I am sorry but the answer is no.
the rollback is available only with firebase hosting.
for the future you should download a backup by simply clicking on 'Export Data' in your project root.
