File Storage NAS:General-purpose NAS backup

Billing

When you use the file backup feature for a NAS file system for the first time, you are eligible for a 30-day free trial. After the trial period ends, you can choose to renew or suspend the backup plan. For detailed billing information, see Billing of Cloud Backup.

Notes

When you create a backup plan or associate a backup policy for the first time, Cloud Backup automatically creates the service-linked role AliyunServiceRoleForHbrNasBackup to obtain the required resource permissions. Follow the prompts in the authorization dialog box to grant the permissions.

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 then click Create Backup Plan.

5. In the Create Backup Plan panel, configure the following parameters and click OK.

   1. Configure the basic parameters.

      Important

      • About the free trial plan

        The free trial plan is enabled by default for a quick start. However, it has limitations: you cannot edit the backup path or backup cycle, each free backup plan uses a separate backup vault, and you cannot change the backup vault after switching to a paid plan. If you plan to back up all data to a single backup vault in the future, we recommend clicking Switch to Paid Plan to unlock the full features.

      • About the disaster recovery capability of a backup vault

        If the backup vault in your current region is a locally redundant backup vault, the system displays a message indicating this. We recommend that you switch to a paid plan to enable cross-region replication to mitigate the risk of a single-datacenter disaster in the current region. Alternatively, you can select a region that supports a zone-redundant backup vault.

      Parameter	Description
      File System	From the drop-down list, select the file system to back up.
      Pay After Trial Ends	Specifies whether to convert the free backup plan to a paid plan after the trial ends.
      Plan Name	Enter a name for the backup plan. If you leave this field empty, the system assigns a random name.
      Start Time	Select the time when the backup starts. The time is accurate to the second.

   2. Optional: If you want fine-grained control over the backup plan, click Switch to Paid Plan in the free trial description for the file system to configure the advanced settings described below.

      Parameter	Description
      Backup file path	Enter the path that you want to back up. If you enter the root directory (/), the system backs up all directories and files in the file system. For example, /nas/folder backs up only the specified directory, and / backs up the entire file system.
      Backup file rules	Configure rules to specify which files to back up. Include all files: All files are backed up. Include specified files or Exclude specified files: Manually enter a list of files in the file list text box. Files are backed up according to the rule.
      Backup policy	Select a backup policy from the drop-down list. Cloud Backup automatically backs up the data source according to the selected backup policy. A backup policy includes operations such as backup vault encryption, backup interval, backup retention period, cross-region replication policy, automatic backup archiving, and virus detection for backup points, helping you flexibly manage data source assets. If the default backup policy does not meet your backup 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

   • You can view the status of executed backup jobs and the volume of backed-up data on the Backup Jobs tab.

   • If the status of a backup job has not been updated for a long time, click Refresh in the upper-right corner of the page and then check the job status again.

Restore files

Follow these steps to restore a single NAS file system within the same region.

Cloud Backup saves only file data. If a file system is deleted, you can only restore its backed-up files to another file system. The mount target, operation logs, recycle bin, and other configurations of the original file system cannot be restored from the backup.

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 Data Restoration tab, and then click Create Restore Job.

5. In the Create Restore Job panel, configure the following information.

   1. In the Select Backup step, confirm or change the backup point to restore, and then click Next.

   2. In the Select Items to Restore step, select the Restore Items, and then click Next.

      Parameter

      Description

      Restore Items

      Select the items to restore. All files: All files from the selected source NAS instance will be restored. Specified files: Select the folders or files to restore. You can also manually enter a file list in the Enter Paths box to restore specified files from the selected NAS instance based on rules. Exclude specified files: Select the folders or files that you do not want to restore. You can also manually enter a list of files to exclude in the Enter Paths box. All other files will be restored. Enter one path per line in the file list. Each line must start with the last folder of the source backup path. For example, if the backup path is /test/data and you want to restore file.txt and abc from the data folder, enter the paths in the following format. /data/file.txt /data/abc

   3. In the Restore Destination step, select the File System in the region to which you want to restore, and then click Next.

   4. In the Destination Path step, configure the restore path, and then click Create.

      Parameter	Description
      Restore Path Type	Select the restore path type. Specified path: Configure a new path and restore the files to this directory. Original path: Restore the files to the original path from which they were backed up.
      Destination Path	This parameter is required only when Restore Path Type is set to Specified path. It specifies the restore path. For example, /nas/abc.
      If a file with the same name exists in the restore path	Skip this file. Overwrite the file with the same name in the restore path. Compare update times (accurate to the second) and keep the latest version.
      Scan for viruses upon restoration	If you enable this feature, Cloud Backup scans all files for viruses during restoration. Files that are detected as safe are restored directly. Files that are detected as viruses are not restored. You can find a safe version on the virus scan page.

   After the restore job is created, you can view its progress in the Status column on the Restore Jobs tab.

   Note

   To cancel an in-progress restore job, click Cancel in the Actions column and confirm the cancellation.
