    Menyalin database antar instans RDS SQL Server

    Catatan Penggunaan

    • Instans sumber dan instans target harus milik akun Alibaba Cloud yang sama.

    • Instans target tidak boleh berisi database dengan nama yang sama dengan database yang akan disalin dari instans sumber.

    • Ruang penyimpanan yang tersedia di instans target harus lebih besar dari ruang yang digunakan oleh database yang akan disalin dari instans sumber. Jika ruang penyimpanan tidak mencukupi, tingkatkan penyimpanan secara tepat waktu.

    • Instans sumber dan instans target harus berada di wilayah yang sama (zona boleh berbeda), dan jenis jaringan harus sama.

    • Instans sumber dan target tidak mendukung jenis instans Serverless. Untuk memigrasikan instans Serverless, gunakan DTS untuk migrasi.

    • Saat memasukkan nilai, parameter BackupId atau RestoreTime harus ditentukan. Kesalahan akan dilaporkan jika keduanya tidak diisi.

    Coba sekarang

    Coba API ini di OpenAPI Explorer tanpa perlu penandatanganan manual. Panggilan yang berhasil akan secara otomatis menghasilkan contoh kode SDK sesuai dengan parameter Anda. Unduh kode tersebut dengan kredensial bawaan yang aman untuk penggunaan lokal.

    RAM authorization

    Tabel berikut menjelaskan otorisasi yang diperlukan untuk memanggil API ini. Anda dapat menentukannya dalam kebijakan Resource Access Management (RAM). Kolom pada tabel dijelaskan sebagai berikut:

    • Action: Aksi yang dapat digunakan dalam elemen Action pada pernyataan kebijakan izin RAM untuk memberikan izin guna melakukan operasi tersebut.

    • API: API yang dapat Anda panggil untuk melakukan aksi tersebut.

    • Access level: Tingkat akses yang telah ditentukan untuk setiap API. Nilai yang valid: create, list, get, update, dan delete.

    • Resource type: Jenis resource yang mendukung otorisasi untuk melakukan aksi tersebut. Ini menunjukkan apakah aksi tersebut mendukung izin tingkat resource. Resource yang ditentukan harus kompatibel dengan aksi tersebut. Jika tidak, kebijakan tersebut tidak akan berlaku.

      • Untuk API dengan izin tingkat resource, jenis resource yang diperlukan ditandai dengan tanda bintang (*). Tentukan Nama Sumber Daya Alibaba Cloud (ARN) yang sesuai dalam elemen Resource pada kebijakan.

      • Untuk API tanpa izin tingkat resource, ditampilkan sebagai All Resources. Gunakan tanda bintang (*) dalam elemen Resource pada kebijakan.

    • Condition key: Kunci kondisi yang didefinisikan oleh layanan. Kunci ini memungkinkan kontrol granular, berlaku baik hanya untuk aksi maupun untuk aksi yang terkait dengan resource tertentu. Selain kunci kondisi spesifik layanan, Alibaba Cloud menyediakan serangkaian common condition keys yang berlaku di semua layanan yang didukung RAM.

    • Dependent action: Aksi dependen yang diperlukan untuk menjalankan aksi tersebut. Untuk menyelesaikan aksi tersebut, pengguna RAM atau role RAM harus memiliki izin untuk melakukan semua aksi dependen.

    Type

    Required

    Description

    Example
    DBInstanceId

    string

    Yes

    ID instans sumber. Anda dapat memanggil operasi DescribeDBInstances untuk mengkueri ID instans.

    rm-bp172446ys9cf****
    TargetDBInstanceId

    string

    Yes

    ID instans target. Anda dapat memanggil operasi DescribeDBInstances untuk mengkueri ID instans.

    rm-bp1m71wvzfiq7****
    DbNames

    string

    Yes

    Daftar nama database yang akan disalin. Format: {"nama database instans sumber":"nama database instans target"}. Pisahkan beberapa database dengan koma (,). Contoh:

    • Menyalin satu database: {"zhttest":"zhttest"}

    • Menyalin beberapa database: {"zhttest01":"zhttest01","zhttest02":"zhttest02"}

    Catatan

    Nama database pada instans target dapat berbeda dari instans sumber, tetapi Anda harus memastikan bahwa tidak ada database dengan nama yang sama di instans target sebelum menyalin.

    {"zhttest":"zhttest"}
    BackupId

    string

    No

    ID set cadangan instans sumber. Saat menyalin database menggunakan set cadangan, Anda dapat memanggil operasi DescribeBackups untuk mendapatkan ID set cadangan.
