Di perangkat yang mendukung pencadangan dan menjalankan Wear OS 4 atau yang lebih baru, pengguna dapat mencadangkan
data ke cloud untuk mentransfer data dari perangkat tersebut, dan mereka dapat
memulihkan data dari cloud untuk mentransfer data ke perangkat Wear OS baru. Misalnya, pengguna dapat melakukan pencadangan dan pemulihan di Google Pixel Watch.
Menyimulasikan transfer cloud menggunakan penyimpanan lokal
Untuk menguji alur pencadangan dan pemulihan menggunakan simulasi penyimpanan cloud, jalankan
langkah-langkah ini:
Di Wear OS, kondisi yang diperlukan untuk mencadangkan data secara otomatis sedikit berbeda
dengan kondisi di perangkat seluler. Agar perangkat Wear OS
dapat otomatis mencadangkan data, kondisi berikut harus terpenuhi:
Perangkat sedang mengisi daya.
Perangkat terhubung ke jaringan Wi-Fi. Hal ini diperlukan meskipun
perangkat kompatibel dengan LTE.
Perangkat ini login ke Akun Google.
Minimal 24 jam telah berlalu sejak pencadangan terakhir.
Tidak seperti perangkat lain, perangkat wearable yang menjalankan Wear OS tidak perlu tidak ada aktivitas
sebelum pencadangan terjadi secara otomatis.
Serupa dengan pencadangan dan pemulihan seluler, data pencadangan disimpan dalam folder
pribadi di akun Google Drive pengguna, dibatasi hingga 25 MB per aplikasi. Jika Anda
memiliki aplikasi seluler dan aplikasi Wear OS, cadangan akan disimpan secara terpisah, dan
kedua aplikasi tersebut tidak saling memengaruhi batas ukuran satu sama lain.
Semua data di DataStore--File > DataStore--dicadangkan secara default
kecuali jika Anda secara eksplisit mengecualikan file dan direktori yang sesuai.

This document\nexplains how you can add support for backup and restore in your Wear OS app.\n\nOn devices that support backup and run Wear OS 4 or higher, users can back up\ntheir data to the cloud in order to transfer data off that device, and they can\nrestore data from the cloud to transfer data onto a new Wear OS device. For\nexample, users can [perform backup and restore on Google Pixel Watch](https://support.google.com/googlepixelwatch/answer/13579590#zippy=%2Cpair-your-phone-with-a-new-pixel-watch).\n| **Note:** Cloud backup and restore, where the user restores data to a new Wear OS device, is different from [transferring Wear OS data to a new mobile device](/training/wearables/data/transfer-to-new-mobile), where the user connects their existing Wear OS device to a new mobile device.\n\nSimulate cloud transfer using local storage\n-------------------------------------------\n\nTo test the backup and restore flow using simulated cloud storage, complete\nthese steps:\n\n1. In your app, [enable backup](/guide/topics/data/autobackup#EnablingAutoBackup) and follow the steps outlined\n at [Control backup on Android 12 or higher](/guide/topics/data/autobackup#include-exclude-android-12). For Wear OS, you don't need to\n specify the [additional set of backup rules](/guide/topics/data/autobackup#include-exclude-android-11) to support devices that target\n API level 29 or lower.\n\n | **Note:** If you implement a custom [`BackupAgent`](/guide/topics/data/autobackup#ImplementingBackupAgent), you should avoid calling the [Data Layer](/training/wearables/data/data-layer) inside your backup agent's methods because it may not work correctly if called there.\n2. Connect your device that's running Wear OS 4 or higher to your development\n machine using a [Wi-Fi connection](/training/wearables/get-started/debugging#wifi-debugging).\n\n3. Follow the steps in the guide to [test cloud backup and restore](/guide/topics/data/testingbackup#TestingBackup).\n\nAutomatic backup rules\n----------------------\n\nOn Wear OS, the conditions required to [back up data automatically](/guide/topics/data/autobackup) differ\nslightly from those on mobile devices. In order for a Wear OS device to\nautomatically back up data, each of the following conditions must be true:\n\n- The device is charging.\n- The device is connected to a Wi-Fi network. This is required even if the device is LTE-enabled.\n- The device is signed into a Google Account.\n- At least 24 hours have elapsed since the last backup.\n\nUnlike other devices, wearables running Wear OS aren't required to be idle\nbefore backups occur automatically.\n\nIn addition, the system automatically backs up any [tiles](/training/wearables/tiles),\n[complications](/training/wearables/tiles/complications), [watch faces](/training/wearables/watch-faces), and [watch face user styles](/reference/kotlin/androidx/wear/watchface/style/UserStyle)\nassociated with your Wear OS app.\n\nBackup storage and size limit\n-----------------------------\n\nSimilar to mobile backup and restore, backup data is [stored in a private\nfolder](/guide/topics/data/autobackup#BackupLocation) in the user's Google Drive account, limited to 25 MB per app.\nIf you have both a mobile app and a Wear OS app, the backups are stored\nseparately, and the two apps don't contribute to each other's size limit.\n\nAny data in the `DataStore` -- **Files \\\u003e DataStore** -- is backed up by default\nunless you explicitly exclude the corresponding files and directories.\n| **Caution:** Partial backups aren't supported. If the total size of the files and directories within a Wear OS backup is greater than 25 MB, then no data from the Wear OS app is backed up.\n\nRecommended for you\n-------------------\n\n- Note: link text is displayed when JavaScript is off\n- [Save simple data with SharedPreferences](/training/data-storage/shared-preferences)\n- [DataStore (Kotlin Multiplatform)](/kotlin/multiplatform/datastore)\n- [Working with Proto DataStore](/codelabs/android-proto-datastore)"]]
