Unable to restore

[joseph]

@ivan-petro yes, so what I am wondering is if the separate volume was also restored to 8.2.4 state (i.e alongside the main server disk).

Think of it this way: you have mysql v6 (your main disk) . you store mysql's data in another volume. now you restored mysql with v4 (i.e restored your main disk). it won't start with the data in another volume. this is because the data is of a newer version i.e v6. this is what I am asking. this is possibly why redis is also not starting. most software won't work with old code and new data .

[ivan-petro]

@joseph , ok, how to resolve this?
is there are way to make hard update of cloudron? ignoring state of apps

[joseph]

@ivan-petro depending on the state maybe we have to hotfix the server with 8.3 . but this is mostly a developer tool. if you write to me on support@cloudron.io , i can try to hotfix the server.

[ivan-petro]

@joseph , Ok, I will write. just interesting if I can stop all apps by one command and make hard update to 8.3?

[joseph]

@ivan-petro it's also quite easy to just start afresh using the AWS backup . See https://docs.cloudron.io/backups/#restore-cloudron .

[ivan-petro]

@joseph , but I have separate volumes of apps(
please is it possible just update current to 8.3 ? I am wondering, I just need to ignore state of apps.

[ivan-petro]

@joseph ,

I've set up a new server and am in the process of restoring from AWS backups. However, I noticed that automatic backups were disabled for some apps, and the only available backups on AWS are quite old.

I have already switched Cloudron’s DNS to the new server. The old server is still active, and I would like to manually migrate specific apps from it to the new server.

Could you provide a step-by-step guide or tutorial on how to manually transfer these apps while preserving their data and configurations?

Thanks in advance for your help!

Best regards,
Ivan.

Oh, the whole Cloudron workflow/actions relies on backups. Not sure how much more I can help but let's see . You can try the below but we don't really have any guide or tutorial since what we have is based on backups.

• Copy the contents of /home/yellowtent/appsdata/<appid>/ from the old server into the new server. Copy this into some temp location . Say /tmp/app1/ or something . Do not copy directly into appsdata , this won't work. In that directory, you will see one config.json . If you see the "manifest" field, it will have the appstore id and version (not upstreamVersion).
• Install a fresh app in new server . You can put in the version field in the URL bar if it's not matching to what you noted above.
• After the app installed: Backups -> Import . Select Filesystem and put in /tmp/app1 . Then, select rsync as the format as well.

@joseph , thanks for tutorial!
I did this , but in the end of import I have error:

External Error: Error loading fsmetadata.json:ENOENT: no such file or directory, open '/mnt/cloudron-volume-2/appsdata/46322ece-e828-4c6c-a4a2-e8391f2e395f/fsmetadata.json'

please let me know if this can be fixed

[joseph]

@ivan-petro ah yes, that file is usually created by rsync backup. can you create a dummy file in the root of the /tmp/app1/fsmetadata.json directory like this:

{
    "emptyDirs": [],
    "execFiles": [],
    "symlinks": []
}

Also, forgot to mention, maybe you can also chown -R yellowtent:yellowtent /tmp/app1 . You might get permission errors when importing otherwise.

[ivan-petro]

@joseph thanks for help! yes it helped. app imported , app in "running" state. but for some reason can't start app. it's n8n app.

@ivan-petro getting close! I can only guess that maybe the package version you have installed and the package version you had previously running were different. Can you check the step 2 in my previous steps (that you have the version correct) ?

Have you tried any other app btw?

[ivan-petro]

@joseph You can go ahead and close this thread.

Yes, I did install the same version as my backup, but unfortunately, that didn’t help.
In the end, I had to reinstall the server completely and upgrade to 8.3.1 again.

It’s clear that backups need to be properly saved.
Thanks for your help anyway.
