    Hello, I’m encountering an issue with my Nextcloud backups via rsync to an unencrypted MinIO on a Cloudron server. I’m unable to properly restore a backup—I always get the same error on one file:

    External Error: Error loading fsmetadata.json: ENOENT: no such file or directory, open '/home/yellowtent/appsdata/appid/fsmetadata.json'

    The only backup I’ve been able to restore is the very first (oldest) one from a month ago… How can I fix this? Thank you for your help!

      FYI: Ubuntu 20.04 LTS (Focal Fossa) reached its end-of-life (EOL) on May 31, 2025.
      This means that Ubuntu 20.04 will no longer receive free security patches, maintenance updates, or bug fixes from Canonical. While the system won't stop working, it becomes increasingly vulnerable to security threats.


      Hey @Benoit can you check iniside the minio if the latest backup indeed has files?

      Like my work? Consider donating a drink. Cheers!

        @Benoit for a start check if the backup storage has a fsmetadata.json for the backup which is failing, to make sure the file actually exist on the backup storage side.

          @BrutalBirdie yes i know that and we start OS upgrades. Yes the backups have files. But not all the files because of rsync.
          @nebulon it seems the fsmetadata.json isn't exist... I tried with a new manual backup and the fsmetadata is not created, but we have no error during the backup process.

            Actually also with rsync all files should exist for each backup. Can you check the app data to see if that contains the file for a start? It would be at /home/yellowtent/appsdata/<appid>/fsmetadata.json

                but you say it is not uploaded to minio then afterwards during a backup?

                  Yes, no fsmetadata.json on minio. I can only restore the oldest backup without errors. All the others fail and I always get the same error. Naturally, when I retry the task, Nextcloud ends up either empty or in an error state.

                    It really should be uploaded just like all the other files. You should see something like box:backupformat/rsync Adding fsmetadata.json early on during the backup process.

                    Maybe we have to debug this on your instance then to see what happens, if you don't see any error in the backup logs itself. For this please enable remote ssh support and send us a mail to support@cloudron.io with Cloudron details.

                        @Benoit thanks for your patience! The issue was that listObjects API call in minio is not returning all objects. Some bug in minio. Moving to listObjectsV2 API makes it work.

                        Fixed in https://git.cloudron.io/platform/box/-/commit/48bf21a537d634167e6477d2671794056b87a592
