Fungsi pemulihan mengembalikan data produksi ke titik waktu tertentu. Anda dapat memulihkan sistem file lokal, sistem file NFS yang dipetakan, atau sistem file SMB yang dipetakan ke host aslinya, dengan mengganti sistem file yang ada.
Pemulihan sistem file
Saat Anda memulihkan sistem file, perangkat cadangan/pemulihan:
Menggantikan file apa pun di disk produksi dengan versi dari image cadangan.
Menambahkan file apa pun yang ada di image cadangan ke disk produksi, meskipun file tersebut tidak lagi ada di disk produksi.
Membiarkan file apa pun di disk produksi yang tidak ada dalam image cadangan.
Dalam kasus yang jarang terjadi saat data produksi berada di disk atau di pool penyimpanan eksternal yang ditampilkan oleh alat pencadangan/pemulihan, pemulihan akan menggantikan seluruh volume atau perangkat blok, sehingga sistem file akan kembali ke kondisi persis seperti saat pencadangan: Semua file di disk produksi yang tidak ada dalam image cadangan tidak akan ada lagi di disk produksi setelah pemulihan.
Durasi waktu yang diperlukan untuk menyelesaikan operasi pemulihan bergantung pada jumlah data yang terlibat.
Memulihkan sistem file
Gunakan petunjuk ini untuk memulihkan sistem file dari image cadangan.
Dari konsol pengelolaan Layanan Pencadangan dan DR, klik
Pengelola Aplikasi, lalu pilih Aplikasi dari menu drop-down.
Halaman Applications akan terbuka.
Pilih gambar yang ingin Anda pulihkan, lalu pilih Akses dari
daftar drop-down di bagian bawah halaman Aplikasi.
Halaman Akses akan terbuka dan mencantumkan gambar yang diambil dalam tampilan ramp linimasa.
Untuk mengetahui informasi selengkapnya tentang tampilan, lihat
Mengakses tampilan ramp linimasa gambar.
Dialog peringatan akan terbuka.
Baca, lalu masukkan DATA LOSS untuk mengonfirmasi.
Bergantung pada konfigurasi Anda, peringatan kedua mungkin muncul. Jika ya,
Anda harus memasukkan OVERWRITE OTHER APPS untuk mengonfirmasi operasi pemulihan.
Tugas pemulihan dimulai. Anda dapat memverifikasi bahwa operasi pemulihan berhasil dengan melihat status tugas di Monitor.
Memulihkan sistem file SMB yang dipetakan

Halaman Applications akan terbuka.
Pilih gambar yang dipetakan yang ingin Anda pulihkan.
Pilih Akses dari daftar drop-down.
Halaman Akses akan terbuka dan menampilkan gambar yang diambil di tampilan ramp linimasa. Untuk mengetahui informasi selengkapnya tentang tampilan, lihat Mengakses tampilan ramp linimasa gambar.
Pilih gambar, lalu pilih Pulihkan dari daftar operasi akses.
Halaman Restore akan terbuka.
Pilih satu volume atau beberapa volume yang akan dipulihkan. Secara default, semua volume dipilih.
Klik Kirim.
Dialog peringatan akan muncul.
Baca dialog, lalu masukkan DATA LOSS untuk mengonfirmasi.
Bergantung pada konfigurasi Anda, peringatan kedua mungkin muncul. Jika ya,

You can restore a local file system, mapped\nNFS file system, or mapped SMB file system to its original host,\noverwriting the existing file system.\n\nFile system restoration\n-----------------------\n\nWhen you restore a file system, the backup/recovery appliance:\n\n- Replaces any files on the production disk with the version from the backup image.\n- Adds to the production disk any files that are in the backup image, even if they are no longer on the production disk.\n- Leaves in place any files on the production disk that are not in the backup image.\n\nIn rare cases in which the production data resides on a disk or on an external\nstorage pool presented by the backup/recovery appliance, restores replace the\nentire volume or block device, so the file system reverts to exactly what it was\nat the time of backup: Any files on the production disk that are not in the\nbackup image will no longer be on the production disk after restore.\n\nThe amount of time required to complete a restore operation depends on the\namount of data involved.\n\nRestore a file system\n---------------------\n\nUse these instructions to restore a file system from a backup image.\n\n1. From the Backup and DR Service management console, click\n **App Manager** and select **Applications** from the drop-down menu.\n\n The **Applications** page opens.\n2. Select the image that you want to restore, and then choose **Access** from\n the drop-down list at the bottom of the **Applications** page.\n\n The **Access** page opens listing captured images in the timeline ramp view.\n For more information on the view, see\n [Access the timeline ramp view of an image](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list#access-time).\n | **Note:** If you are restoring an NFS image, the **Advanced NFS Settings** must only be changed after consulting with your support representative.\n\n A warning dialog opens.\n3. Read it and then enter `DATA LOSS` to confirm.\n\n4. Depending on your configuration, a second warning may appear. If so,\n you need to enter `OVERWRITE OTHER APPS` to confirm the restore operation.\n\n The restore job starts. You can verify that the restore operation is\n successful by viewing the job status in **Monitor**.\n\nRestore a mapped SMB file system\n--------------------------------\n\nUse these instructions to restore a point-in-time mapped SMB file system image.\n\n1. From the Backup and DR Service management console, click\n **App Manager** and select **Applications** from the drop-down menu.\n\n The **Applications** page opens.\n2.
