Back up NAS files - Cloud Backup - Alibaba Cloud Documentation Center

You can use a Cloud Backup client to back up files from Network File System (NFS) file systems that are deployed on on-premises servers. Cloud Backup provides two types of backup plans: instant backup plan and scheduled backup plan. You can select a backup plan type based on your business requirements.

Create an instant backup plan

If you require only a one-time full backup, perform the following steps to create an instant backup plan:

Log on to the Cloud Backup client.
In the left-side navigation pane, click Backup. In the upper-right corner of the Backup Jobs page, click Create Backup Job.
On the Basic Settings tab of the Create Backup Job dialog box, configure the parameters. The following table describes the parameters.
- Source: Enter the path to the mount target of the NAS file system.
- Running Plan: Select Instant.
Important
Volume Shadow Copy Service (VSS) is not supported for NAS backup.
Optional. Click the Bandwidth Throttling tab. Set Work Hours. In the Throttling field, enter the maximum bandwidth that can be used for backup during the specified throttling period. Then, click Add.
Note
- The throttling period is accurate to hours. You can add multiple throttling periods based on your requirements.
- If you need to modify a throttling period, find the throttling period, click Delete in the Actions column, and then specify a new throttling period.
- The maximum bandwidth must be at least 1 MB/s.
Click Submit.
Note
After a backup job is started, you can perform the following operations on the Backup Jobs page:
- View the progress of the backup job.
- Click Cancel or Retry in the Actions column to cancel or retry the backup job.
- If some files fail to be backed up, find the related backup job on the Backup Jobs tab. Click Download in the Errors column to download the error report.

Create a scheduled backup plan

If you require scheduled backup, perform the following steps to create a scheduled backup plan:

Open a browser and enter http://localhost:8011 in the address bar. On the page that appears, enter the password to log on to the Cloud Backup client.
Note
- If you are using an intermediate host, replace localhost with the IP address of the server or virtual machine.
- Port 8011 is the default port that you can use to log on to the Cloud Backup client. If port 8011 on the server or virtual machine is occupied by another application, you can specify another port number. For more information, see How can I select a different port as the logon port of a file client?
In the left-side navigation pane, click Backup Policies.
On the Backup Policies page, click Create Policy.

In the Create Policy dialog box, configure the Name and other parameters.

Parameter	Description
Name	The name of the backup policy.
Frequency	The interval at which backup is performed. Units: Hours. Valid values: 1 to 23. Days. Valid values: 1 to 6. Weeks. Valid values: 1 to 4.
Backup Time	The time to start the first backup. The first backup is a full backup.
Retention	The retention period of backup data. Units: days, months, or years. Maximum retention period: 3650 days (10 years).

Click Submit.
After the scheduled backup policy is created, perform the following steps to start a scheduled backup job:
1. Log on to the Cloud Backup client.
2. In the left-side navigation pane, click Backup.
3. In the upper-right corner of the Backup Jobs page, click Create Backup Job.
4. In the Create Backup Job dialog box, click the Basic Settings tab. If you are creating a backup job for an on-premises NFS file system, configure the following parameters:
  - Source: Enter the path to the mount target of the NAS file system.
  - Running Plan: Select Scheduled.
  - Backup Policy: Select the created backup policy.

5. Optional. Click the Bandwidth Throttling tab. Set Work Hours. In the Throttling field, enter the maximum bandwidth that can be used for backup during the specified throttling period. Then, click Add.
  Note
  The throttling period is accurate to hours. You can add multiple throttling periods based on your requirements.

However, Cloud Backup retains the backups that are created by the backup job. You can still restore data from these backups.
  If some files fail to be backed up, find the related backup job on the Backup Jobs tab. Click Download in the Errors column to download the error report.
