Can't import backup: Error loading fsmetadata.json

[difficult222]

Hey,

I installed two instances of Omeka S, test and production, both Omeka S 4.2.0. The production app get's backuped weekly to an Hetzner S3 (rsync).

I want to import a backup to the test app.

It starts "Importing - Downloading"... it takes some time. But then afters some time there's an error:

Error - Error loading fsmetadata.json:ENOENT: no such file or directory, open ...

I can find this file in two locations in my Object Storage:

1. backup/2026-01-24-060000-602/app_name_v1.4.0/fsmetadata.json

2. backup/snapshot/app_0245750c-82b5-4b4c-b6ea-15c53d6046b6/fsmetadata.json

What's the problem?

Hello @difficult222

Thanks for reporting.
Can you please check the file size and report that here?

[joseph]

Can you check the import logs (part of the app logs button)? It's probably not downloading the backup properly.

[difficult222]

@james Of which file?

[james]

Hello @difficult222

@difficult222 said in Can't import backup: Error loading fsmetadata.json:

I can find this file in two locations in my Object Storage:

backup/2026-01-24-060000-602/app_name_v1.4.0/fsmetadata.json

backup/snapshot/app_0245750c-82b5-4b4c-b6ea-15c53d6046b6/fsmetadata.json

These two files. Can you check the size of these two files and also the content?

Also, since the error is with this file /home/yellowtent/appsdata/f6e82f5e-ae79-403b-b824-f96d8989b4f4/fsmetadata.json
Can you check if this file really does not exist?

[difficult222]

Sure! Thanks for the instructions!

The two fsmetadata.jsons files in Object Storage look like this:

{
  "emptyDirs": [
    "./data/modules/BulkEdit/test/BulkEditTest",
    "./data/files/preload",
    "./data/files/import",
    "./data/files/backup/log"

  "execFiles": [

      "path": "./data/themes/default",
      "site": "/app/code/themes_vanilla/default"
    }
  ]
}

How can I check if /home/yellowtent/appsdata/f6e82f5e-ae79-403b-b824-f96d8989b4f4/fsmetadata.json exists?

When I start the terminal I only have home/cloudron/..., but no home/yellow-tent/...

[james]

Hello @difficult222
For this you need to ssh into your Cloudron server.
There you can check /home/yellowtent

[difficult222]

I sshed into the server, and the file really does not exist:

cloudron# ls /home/yellowtent/appsdata/f6e82f5e-ae79-403b-b824-f96d8989b4f4/fsmetadata.json   

ls: cannot access '/home/yellowtent/appsdata/f6e82f5e-ae79-403b-b824-f96d8989b4f4/fsmetadata.json': No such file or directory

@difficult222 there is something wrong with that output . It has 2026-01-24-060000-602 and snapshot . These directories should not be there (in fact, they are part of backups).

Can you check if those directories exist in the Hezner S3 also? If it did, something has gone wrong with how the backups are getting created . Could it be that you changed the prefix of a site? Or used a prefix that already had some contents from previous backup setup?
