Tachiyomi Backup Guide 2026: How to Backup & Migrate Tachiyomi, Mihon and Manga Rock

Deadline

Important: Tachiyomi Backup Support Ends After Mihon 0.21

Quick answer: In Mihon, open More, tap Data and storage, then choose Create backup and save the file somewhere safe. On the new phone or app, open that same screen, tap Restore backup and pick the file. Install your extensions and log into your trackers first, then move your downloads folder and reindex it.

On 11 October 2026 the Mihon team released version 0.21.0 with a clear warning in its changelog. This is the last major Mihon version that can restore files in the old Tachiyomi format, which uses the .tachibk extension, and the last one that runs extensions built for Tachiyomi 1.4. After the next update arrives, the only way to use an old Tachiyomi backup will be to restore it on 0.21 first and then update the app. Anyone holding an old file from before the shutdown should restore it now, while that door is still open.

Heads up: The developers added a second warning to the same release that matters just as much. Version 0.21.0 merges duplicate entries and chapters left over from older versions, and that merge cannot be undone, so you need a fresh copy of your library before you update.

The latest build at the time of writing is Mihon 0.21.3, released on 25 October 2026, and it makes creating and restoring big libraries faster and lighter on memory. If your phone ever crashed while restoring a huge library, install this version before you try again.

Automatic

Enabling Automatic Backup

A manual copy only protects the day you made it, while an automatic Tachiyomi backup keeps saving fresh copies without you thinking about it. Turning it on takes less than a minute, and it protects you from a broken phone or a bad update that arrives before your next manual copy.

How to Turn On Automatic Backups

Open Data and storage in Mihon and find the backup frequency option. Pick an interval that matches how often you read, such as daily for heavy readers or weekly for lighter use. Mihon will then create a new backup file on that schedule in the background. Scheduled copies skip the optional “All read entries” data, so make a manual one now and then if you follow a lot of manga outside your library.

Where Automatic Backups Are Saved

Every automatic Tachiyomi backup lands in a folder named autobackup inside the storage location you picked during setup. You can check or change that storage location from the same settings page whenever you like. Open the autobackup folder with any file manager and you will find the saved files there, ready to copy to another device.

Sync Backups to Google Drive Automatically

Mihon has no built-in sync between devices, but its own documentation points to a simple workaround using the FolderSync app.

1. Turn on automatic backups and set the frequency.
2. Install FolderSync from the Play Store.
3. Pair the autobackup folder with a folder in Google Drive.
4. On your second device, download the newest Tachiyomi backup from Google Drive and restore it.

Autosync for Google Drive and Tasker can do the same job if you already use either of them. This setup is not live sync, because the second device only gets your progress when you restore the latest file. It still means a lost phone costs you only the reading you did since the last scheduled copy.

Restore

Restoring a Tachiyomi Backup

Restoring is the second half of any backup and restore Tachiyomi routine, and a little preparation decides whether your library comes back complete. The same steps work for a fresh Mihon file and for an older Tachiyomi backup, as long as Mihon 0.21 handles the older one.

Before You Restore: Quick Checklist

Run through this short list before you restore a Tachiyomi backup, because the app can only reconnect what is already set up.

• Install the latest Mihon from mihon.app or the official GitHub page.
• Add the extension repos you used before and install every extension your library needs.
• Log into each tracker you used, such as MyAnimeList or AniList.
• Set your storage location in Data and storage.

Mihon lists any missing trackers or extensions on the restore screen, which gives you one last chance to fill gaps before the import starts.

Step-by-Step Restore

With the checklist done, the restore itself takes only a few taps.

1. Go to More and open Data and storage.
2. Tap Restore backup.
3. Pick your file in the system file picker, which Mihon has used since version 0.21.0.
4. Read the list of missing trackers or extensions and fix anything it shows.
5. Start the restore and wait for the notification that says it finished.

If you restore into a library that already has entries, Mihon 0.21 keeps the furthest read progress and the earliest date added for each series. Reading you did on either device stays safe, so you never have to choose one phone over the other.

Restore Your Downloaded Chapters

Downloaded chapters are separate files, so they need their own small transfer once the Tachiyomi backup is restored.

1. On the Data and storage screen, check which storage location Mihon is using.
2. Copy or move your old chapters into the downloads folder inside that location.
3. Open Settings, then Advanced, and tap Reindex downloads.

Mihon then scans that folder and marks every matching chapter as downloaded again. If chapters still show as missing, users on the Mihon GitHub page report that closing the app and clearing its cache in Android settings fixed it. The folder path has to match the one Mihon expects, so a wrong folder name is the first thing to check when the reindex finds nothing.

Transfer

Transfer Tachiyomi Between Phones, PC and SD Card

Moving to a new phone or keeping a copy on a computer uses the same file, so the only real question is how you carry it from one place to another. These three routes cover almost every setup readers ask about, and each one starts with a fresh copy made on the day you move.

Move Your Backup to a New Phone

Create a fresh Tachiyomi backup on the old phone right before you switch, so the file includes your latest chapters. Send it to the new phone through Google Drive, a USB cable and a computer, or any file-sharing app you trust. Install Mihon on the new phone, finish the checklist from the restore section, then load the file from Data and storage. Copy the downloads folder across as well if you want offline chapters, and run Reindex downloads once it arrives. Keep the old phone untouched until the new one shows your full library and tracker links.

Back Up Tachiyomi on PC

A PC backup is simply a second copy of your files on a computer, which protects you if the phone is lost or stolen. Connect the phone with a USB cable, open its storage on the computer and copy the downloads folder plus the autobackup folder with your latest Tachiyomi backup. Put them inside a dated folder on your drive so you can tell old copies from new ones. If you want to read on the computer too, Suwayomi is a free and open source server that restores Mihon-compatible backups. Suwayomi can also stay in sync with Mihon through its own extension and tracker, so reading progress moves between phone and PC. Our Tachiyomi on PC guide walks through the full setup.

Save Backups and Downloads on an SD Card

If your phone has an SD card slot, you can point Mihon at the card to keep large downloads off your internal storage. Open Data and storage, change the storage location to a folder on the SD card and let Mihon create its folders there. Your autobackup folder moves along with it, which is handy but risky, because a failed card takes your downloads and every saved backup copy together. Copy the latest file to Google Drive or a computer as well, so one broken card never wipes out everything.

Sources

Migrating Manga Between Sources (Source Migration)

Source migration moves a series from one source to another without losing your read progress, which is a different job from moving your Tachiyomi backup between devices. You need it when a source shuts down, stops updating or another source simply has newer chapters. Mihon lets you migrate one series at a time or a whole source in one batch.

Migrate a Single Series

Moving one series first is the safest way to learn how migration behaves before you touch your whole library.

1. Open the series you want to move.
2. Tap the overflow menu and choose Migrate.
3. Wait while Mihon searches every installed and enabled source.
4. Tap the matching series in the source you want.
5. Choose which data you want to transfer and confirm.

Downloaded chapters from the old source are not moved, and they can stay behind as leftover files on your storage. Delete those folders with a file manager afterwards so they do not quietly fill your phone.

Mass Migrate Your Whole Library

Mihon added mass migration in version 0.19.0 in August 2025, so you can move many series in one batch instead of one by one. Open Browse, switch to the Migrate tab and pick the source you want to leave behind. Select the series to move, set your target sources in order of preference and let Mihon match each title.

Version 0.19.4 fixed mass migration so it uses the same search terms as single migration, which makes matches more reliable on current builds. Check the results before you confirm, because similar titles can sometimes match the wrong series.

Manga Rock

How to Transfer Your Manga Rock Library to Tachiyomi

Many readers still look for a way to transfer Manga Rock to Tachiyomi, so it helps to be honest about what is possible today. A full transfer only works if you saved your Manga Rock data before the app disappeared, and everyone else will need to rebuild by hand from memory, a tracker list or an old screenshot.

What Happened to Manga Rock?

Manga Rock was run by Not A Basement Studio, and in September 2019 the team pulled the app from the App Store and Play Store. That removal was the first step of a plan to rebrand as a licensed service called MR Comics. In April 2020 Manga Rock shut down completely, and the same team launched INKR Comics, a platform built on licensed manga and comics. Since then, the only way to rescue an old Manga Rock library has been through community tools made by fans.

Can INKR Restore Your Manga Rock Favorites?

INKR cannot bring back your old library, and signing in with your old Manga Rock account does not change that. INKR states that Manga Rock reading history and Favorites cannot be transferred, because it is a separate licensed service and not a restored copy of the old app. Many titles in the old Manga Rock catalog were unofficial scans, so they could never appear in a licensed catalog anyway.

The Old Method: mr2tachiyomi (Legacy)

If you still have a Manga Rock backup from before 2020, the community tool mr2tachiyomi by waicool20 on GitHub can turn it into a file the Tachiyomi family can read. It needs Java on a computer, and the steps are technical, so set aside some time for it.

1. Find your old mangarock.db file, or the Helium backup of the Manga Rock app.
2. Run mr2tachiyomi on your computer and open that file.
3. Save the output, which is a .json file.
4. Install TachiyomiAZ, the only fork that still reads .json files, and restore it there.
5. Create a new Tachiyomi backup in TachiyomiAZ, which uses the modern format.
6. Restore that new file in Mihon 0.21 and use source migration to move each series to a working source.

The tool’s own notes say the import fails unless the matching source extensions are installed. Since the Manga Rock source no longer exists, treat this route as a last-chance rescue and verify on your device that it still works.
