Suggestions for backups

Enabling automatic backups

It is highly recommended to enable automatic backups to ensure you can recover in case of any issues.

How to enable automatic backups

  1. Go to More -> Data and storage.
  2. Set a backup frequency to schedule automatic backups. This way, you can recover from catastrophic failures.

Syncing backups with external cloud services

Cross device sync in Mihon is not currently available, but users can use Autosync for Google Drive in order to sync backup files to Drive automatically with the following steps:

  1. Install the app from the link above
  2. Enable Automatic Backups and set it to your desired frequency and storage location.
  3. Download the latest backup from Google Drive and restore to whatever device you have

Users who are familiar with FolderSync or Tasker can setup auto sync of their backups similarly.

Additional information for forks


This section explores some extra details regarding forks.

All Mihon (and Tachiyomi) forks support the .tachibk/.proto.gz format to backup/restore your library.

In addition, some forks have specific limitations regarding backup restoration:

  • All forks have fork-specific settings and changes that might be saved in Backups. Such settings are not restored in Mihon and will get lost when creating a new backup.

    For Example: TachiyomiSY has the option to backup/restore saved searches.

    These will NOT be restored to Mihon or its forks.

  • Only TachiyomiAZ supports creating/restoring both legacy .json backups and .proto.gz backups.

    Users are recommended to update their .json backups to use the improved and efficient .tachibk/.proto.gz backups.

Be aware of these limitations when dealing with backups in different Mihon and Tachiyomi forks.
