Karena kompatibel dengan PostgreSQL, berbagai solusi pencadangan yang dikembangkan dan didukung oleh komunitas PostgreSQL juga tersedia untuk database AlloyDB Omni. Secara umum, solusi apa pun yang memungkinkan Anda mencadangkan dari dan memulihkan ke cluster PostgreSQL yang berjalan di penampung Docker juga akan berfungsi dengan AlloyDB Omni.
Cara Anda menyiapkan dan mengoperasikan fitur pencadangan dan pemulihan bergantung pada apakah Anda mengoperasikan AlloyDB Omni di server individual menggunakan alat command line alloydb, atau apakah Anda menjalankan AlloyDB Omni menggunakan Operator AlloyDB Omni. Bagian berikut akan membahas opsi ini secara lebih mendetail.
Solusi pencadangan server tunggal
Jika Anda menjalankan AlloyDB Omni dalam container di server individual, Google merekomendasikan penggunaan Barman atau pgBackRest, bergantung pada kebutuhan dan preferensi Anda.
Kedua solusi open source ini menyediakan hal berikut:
Fitur pencadangan dan pemulihan data penting, termasuk pemulihan point-in-time
Kompatibilitas dengan database yang kompatibel dengan PostgreSQL dan di-container yang digunakan AlloyDB Omni
Barman memiliki fitur unik berikut:
Cadangan disimpan di server cadangan terpisah yang Anda kelola
Opsi untuk server cadangan berjenjang
Pencadangan dengan kehilangan data yang nyaris nol menggunakan perubahan data yang di-streaming
Opsi untuk pencadangan tanpa kehilangan data menggunakan streaming sinkron
Jika Anda telah men-deploy AlloyDB Omni ke cluster Kubernetes, maka
Operator AlloyDB Omni menyediakan metode pencadangan dan pemulihan tanpa
perlu konfigurasi lebih lanjut.

In general, any solution that allows\nyou to back up from and restore to a PostgreSQL cluster running in a Docker\ncontainer will also work with AlloyDB Omni.\n\nThe way that you set up and operate backup and restore features depends on\nwhether you operate AlloyDB Omni on individual servers using the\n`alloydb` command-line tool, or whether you run AlloyDB Omni\nusing the AlloyDB Omni Operator. The following sections explore these\noptions in further detail.\n\nSingle-server backup solutions\n------------------------------\n\nIf you run AlloyDB Omni in a container on individual servers, then\nGoogle recommends using either [Barman](https://pgbarman.org) or\n[pgBackRest](https://pgbackrest.org/), depending on your needs and preferences.\n\nBoth of these open source solutions provide the following:\n\n- Essential data backup and restore features, including point-in-time recovery\n- Compatibility with the containerized PostgreSQL-compatible databases that AlloyDB Omni uses\n\nBarman has the following distinct features:\n\n- Backups stored in a separate backup server that you manage\n- The option for cascading backup servers\n- Near-zero-data-loss backups using streamed data changes\n- The option for zero-data-loss backups using synchronous streaming\n\nFor more information, see [Set up Barman for AlloyDB Omni](/alloydb/omni/15.5.5/docs/install-configure-barman).\n\npgBackRest has the following distinct features:\n\n- Parallelized backup jobs\n- Full, incremental, or differential backups\n- Encrypted backups\n- Backup compression and checksums\n- The option to restore only specific databases\n\nFor more information, see [Set up pgBackRest for AlloyDB Omni](/alloydb/omni/15.5.5/docs/set-up-pgbackrest).\n\nKubernetes backup solutions\n---------------------------\n\nIf you have deployed AlloyDB Omni onto a Kubernetes cluster, then\nthe AlloyDB Omni Operator provides backup and restore methods without the\nneed for any further configuration.\n\nFor more information, see [Back up and restore in\nKubernetes](/alloydb/omni/15.5.5/docs/backup-kubernetes).\n\nWhat's next\n-----------\n\n- [Set up Barman for AlloyDB Omni](/alloydb/omni/15.5.5/docs/install-configure-barman)\n\n- [Set up pgBackRest for AlloyDB Omni](/alloydb/omni/15.5.5/docs/set-up-pgbackrest)\n\n- [Back up and restore in Kubernetes](/alloydb/omni/15.5.5/docs/backup-kubernetes)"]]
