File Storage NAS:Back up a General-purpose NAS file system

Billing

Your first NAS backup plan includes a 30-day free trial. When the trial period expires, you can renew or suspend the backup plan. For more information, see Billing methods and billable items.

Usage notes

• The first time you create a backup plan or associate a backup plan with a backup policy, Cloud Backup automatically creates a service-linked role for Cloud Backup named AliyunServiceRoleForHbrNasBackup. This role is used to obtain permissions to access related resources. In the dialog box that appears, grant the role as prompted.

• During a NAS backup or restore job, the maximum length of a file name is 248 bytes. If a file name exceeds this limit, the file cannot be backed up or restored. The job is then marked as partially completed.

• When you restore NAS files, you cannot restore socket files or hard links.

Back up files

1. Log on to the NAS console.

2. In the left-side navigation pane, choose Data Service > File Backup (Cloud Backup Service).

3. In the top navigation bar, select a region.

4. On the File Backup page, click the Backup Plans tab and click Create Backup Plan.

5. In the Create Backup Plan panel, configure the following parameters to create a backup plan, and then click OK.

   1. Configure basic settings.

      Important

      • About the free trial plan

        The 30-day free trial is enabled by default, allowing you to quickly test the features. However, the trial has limitations, such as the inability to edit the source path or backup cycle, and each free backup plan uses a separate vault. Once you upgrade to a paid plan, you cannot change the backup vault. If you want to back up all your data to a single vault, click Switch to Paid Plan to unlock all features.

      • About the disaster recovery capability of backup vaults

        If your backup vault is locally redundant, a message will be displayed: "The backup vault in your current region is a locally redundant storage backup vault." Switch to the paid plan to enable cross-region backup replication. This protects your data from a single data center failure. Alternatively, choose a zone-redundant backup vault from the following supported regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Hong Kong), Japan (Tokyo), Singapore, Indonesia (Jakarta), and Germany (Frankfurt).

      Parameter	Description
      File System	Select the NAS file system that you want to back up.
      Pay After Trial Ends	Choose whether to automatically convert the plan to a paid subscription after the free trial ends.
      Plan Name	Enter a name for the backup plan. If you do not configure this parameter, a random name is specified.
      Start Time	Specify the exact time (down to the second) for the first backup job to start.

   2. Optional. To configure a fine-grained backup plan, click Switch to Paid Plan to enable advanced settings, and then configure the parameters. The following table describes the parameters.

      Parameter	Description
      Source Paths	Enter a path, for example, /nas/folder.
      Backup Rule	Configure the rule to back up files. Only files that match the rule are backed up. Include All Files: Backs up all files. Include Files or Exclude Files: Manually enter a list of files. Files are backed up based on the specified rule.
      Backup Policy	Select a backup policy from the drop-down list. Cloud Backup automatically backs up data sources based on the backup policy that you configure. A backup policy includes settings such as the backup vault encryption method, backup interval, retention period, cross-region replication policy, automatic data archiving, and virus detection for backup points. This helps you flexibly manage data sources. If the default backup policy does not meet your requirements, click Create Policy or Edit Policy to manage backup policies. For more information about the parameters in a backup policy, see Policy center.

      Note

      • On the Backup Jobs tab, view the status of the backup jobs, the data size of the backup files, and other details.

      • If the job status does not update, click the Refresh button in the upper-right corner of the page.

      Select the items to restore. Include All Files: Restores all files in the selected source NAS instance. Include Files: Select the folders or files that you want to restore. You can also manually enter a list of files in the Enter Paths box to restore specific files from the selected NAS instance. Exclude Files: Select the folders or files that you do not want to restore. You can also manually enter a list of files that you do not want to restore in the Enter Paths box. All files in the remaining paths are restored. Enter one path per line in the file list. Each line must start with the last folder of the source path. For example, if the source path is /test/data and you want to restore file.txt and abc in the data folder, enter the paths in the following format. /data/file.txt /data/abc

      File Conflict Policy	Skip the file. Overwrite the existing file. Compare the update times and keep the newer version.
      Virus Detection During Restoration	If you enable this option, Cloud Backup scans all files for viruses before restoring them. For more information, see the console or Backup point virus detection.
