Backup of Home Assistant stopped working (Core2024.12.3, Errno 5, I/O Error)

Installation

Suddenly I noticed that my daily backups arent working anymore. When trying to manually start the backup it doesnt work. I can do a partial backup, but only of folders and addons. Its the core home assistant backup that is not working anymore. I have no clue to how to solve this and hope there are other people here who know how to solve it. It stopped working after the 9th of december when upgrading ha. Everything else is working as it should

  • Core2024.12.3
  • Supervisor2024.11.4
  • Operating System14.0
  • Frontend20241127.7

Enclosed are the logs:

We cannot help you because you haven’t told us how exactly are you doing this backup to which server and to which disk. So we cannot know where the problem lies. I can tell you that error number 5 means input output error. So it must be a network connectivity problem between your home assistant and your backup server or maybe your disk (if it’s a local backup) is simply giving up the ghost.

Good luck.

Hi, i have tried both to backup to a network disk and to the local disk, same problem so it doesnt seem to be a problem with the disk. It seems it has something todo with the core files. Everything else works to backup. I have also found older post that has the same problem but unfortunately no solution to this problem.
