Can't import backup: Error loading fsmetadata.json

[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": [
    "./data/omeka-s-cli.phar"
  ],
  "symlinks": [
    {
      "path": "./data/modules/Ldap",
      "site": "/app/code/modules_vanilla/Ldap"
    },
    {
      "path": "./data/themes/default",
      "site": "/app/code/themes_vanilla/default"
    }
  ]
}

size: 428 byte

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/...

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

The content of the directory:

cloudron# cd /home/yellowtent/appsdata/f6e82f5e-ae79-403b-b824-f96d8989b4f4/
cloudron# ls -la

@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?

[difficult222]

right now, it looks like that in Hetzner Object Storage:

No, I didn't change the prefix of a site.

Should I just delete everything on Hetzner and start again?

[difficult222]

I deleted everything on S3 and then made a fresh backup and tried to import again: Same error.

This is the structure on hetzner:

Might be something wrong with the way I create the backup?
