Layanan Pencadangan dan DR memungkinkan Anda mengambil data dari sistem file SMB, NFS, dan Filestore produksi, mengelolanya dengan cara yang paling efisien, dan menggunakan salinan virtual data untuk persyaratan bisnis seperti pencadangan, pengujian dan pengembangan, analisis, serta AI.
Saat mengonfigurasi rencana pencadangan untuk sistem file, Anda memiliki setelan
berikut untuk membantu memastikan bahwa Anda mendapatkan persis yang Anda butuhkan:
Kecualikan Pola dan Sertakan Pola: Anda dapat mengecualikan atau menyertakan jenis file tertentu. Dengan menggunakan opsi Kecualikan Pola atau Sertakan Pola,
hanya data yang paling penting yang dicadangkan. Hanya file yang dikecualikan atau disertakan,
hal ini tidak memengaruhi direktori. Pola dapat menyertakan karakter pengganti.
Di Windows, file bernama pagefile.sys dan hiberfil.sys yang muncul di direktori
root drive akan otomatis diabaikan.
Jalur Mulai: Menentukan titik di berbagi file tempat pencadangan dimulai. Jika
kolom Jalur Mulai dibiarkan kosong, pencadangan akan dimulai di direktori root
sistem file yang akan dicadangkan.
Contoh Linux: /usr/local mencadangkan direktori /usr/local.
Contoh Windows: \\SERVERNAME\SHARENAME\abc mencadangkan direktori abc di berbagi file.
Jalur Pemangkasan: Jalur pemangkasan menentukan titik di sistem file tempat
perjalanan direktori berhenti. Jika kolom ini dibiarkan kosong, penelusuran direktori
akan turun ke setiap subdirektori dari jalur awal yang dicadangkan.
Contoh Linux: /usr/local/lib memastikan bahwa tidak ada apa pun dalam /usr/local/lib yang
disalin, tetapi semua direktori dan file lain di /usr/local disalin.
Contoh Windows: \\SERVERNAME\SHARENAME\abc memastikan bahwa tidak ada apa pun dalam
\\SERVERNAME\SHARENAME\abc yang disalin, tetapi semua direktori dan file lain
di \\SERVERNAME\SHARENAME disalin.
Alamat IP titik akses layanan: Hal ini memungkinkan perangkat pencadangan/pemulihan
terhubung ke agen Pencadangan dan DR menggunakan IP resource cluster dan
mencadangkan sistem file dari node cluster yang aktif.
Contoh cara kerjanya: Pencadangan berbasis volume pencadangan dan DR dengan CBT Linux
Hanya blok yang diubah yang dilacak dalam bitmap, tidak ada operasi salin-saat-tulis atau
intensif I/O.
Langkah-langkah berikut menjelaskan proses cara melakukan pencadangan dan
pemulihan data dengan CBT dan image cadangan berbasis volume:
Agen Pencadangan dan DR memiliki CBT untuk melacak blok yang diubah dalam sistem file.
Agen memanggil OS API untuk membekukan atau menjeda perubahan file.
Agen membuat snapshot LVM dari sistem file dan menyintesis bitmap.
Panggilan Agent API untuk mencairkan sistem file.
Agen menyalin blok yang diubah ke appliance pencadangan/pemulihan, yang kemudian menghapus
snapshot dan membuat katalog pencadangan.
Appliance ini mengeluarkan snapshot internal dan menyintesis pencadangan penuh virtual
point-in-time.
Untuk pemulihan data, Pencadangan dan DR langsung memasang disk staging yang dapat ditulis ulang
dan mengaktifkan sistem file secara online.

Using either the Exclude Patterns or Include Patterns option,\n only the most crucial data is backed-up. Only files are excluded or included,\n this does not impact directories. A pattern can include wildcard characters.\n On Windows, files named pagefile.sys and hiberfil.sys that appear in the root\n directory of a drive are automatically ignored.\n\n- Start Paths: Specifies the point in the file share where backup starts. If\n the Start Path field is left blank, backup starts at the root directory of\n the file system to be backed-up.\n\n - Linux example: `/usr/local` backs up the `/usr/local` directory.\n\n - Windows example: `\\\\SERVERNAME\\SHARENAME\\abc` backs up the abc directory on the file share.\n\n- Prune Paths: A prune path specifies a point in the file system where\n directory traversals stop. If this field is left blank, the directory\n traversal descends into every subdirectory of the start paths being backed up.\n\n - Linux example: `/usr/local/lib` ensures that nothing within `/usr/local/lib` is\n copied, but all other directories and files in `/usr/local` are copied.\n\n - Windows example: `\\\\SERVERNAME\\SHARENAME\\abc` ensures that nothing within\n `\\\\SERVERNAME\\SHARENAME\\abc` is copied, but all other directories and files\n in `\\\\SERVERNAME\\SHARENAME` are copied.\n\n- Service access point IP address: This allows the backup/recovery appliance\n to connect to the Backup and DR agent using the cluster resource IP and to\n back up the file system from the active cluster node.\n\nHow it works example: Backup and DR volume-based backup with Linux CBT\n----------------------------------------------------------------------\n\nOnly changed blocks are tracked in the bitmap, there are no copy-on-writes or\nI/O-intensive operations.\n\nThe following steps describe the process for how to perform data backup and\nrecovery with volume-based backup images and CBT:\n\n1. The Backup and DR agent has CBT to track changed blocks in the file system.\n\n2. The agent calls the OS API to freeze or pause file changes.\n\n3. Agent creates a LVM snapshot of the file system and synthesizes a bitmap.\n\n4. Agent API call to unfreeze the file system.\n\n5. Agent copies changed blocks to backup/recovery appliance, which then deletes\n the snapshot and catalogs the backup.\n\n6. The appliance issues an internal snapshot and synthesizes a point-in-time\n virtual full backup.\n\n7. For data recovery, Backup and DR instantly mounts a rewritable staging disk\n and brings the file system online.\n\nWhat's next\n-----------\n\n[Manage hosts and their connected applications](/backup-disaster-recovery/docs/configuration/manage-hosts-and-their-connected-applications)\n\nOther documentation for Backup and DR for file systems\n------------------------------------------------------\n\nThis page is one in a series of pages specific to protecting and recovering\nfilesystems with Backup and DR Service.\nYou can find additional information in the following pages:\n\n- [Backup and DR for file systems](/backup-disaster-recovery/docs/concepts/filesystem-intro)\n- [Manage hosts and their connected applications](/backup-disaster-recovery/docs/configuration/manage-hosts-and-their-connected-applications)\n- [Configure application details and settings to protect file system data](/backup-disaster-recovery/docs/backup/configure-app-settings-for-filesystems)\n- [Apply a backup plan to protect a file system](/backup-disaster-recovery/docs/create-plan/apply-backup-plan-to-filesystem)\n- [Restore a file system to the source](/backup-disaster-recovery/docs/access-data/filesystem-restore)\n- [Mount a file system or file share](/backup-disaster-recovery/docs/access-data/mount-file-system)\n- [Mount and migrate a file system for instant recovery to any target](/backup-disaster-recovery/docs/access-data/filesystem-mount-and-migrate)"]]
