Cloud Backup:Get started with Apsara File Storage NAS backup

Last Updated:Feb 06, 2024

You can back up Apsara File Storage NAS (NAS) file systems in the Cloud Backup console. This topic describes the steps required for this scenario.

The following procedure shows how to back up a NAS file system in the Cloud Backup console.


  1. Activate Cloud Backup

    You are not charged for activating Cloud Backup. If you create a backup vault, you are charged for the storage usage of the backup vault. For more information, see Billing methods and billable items.

  2. Back up a NAS file system

    When you create a backup plan, configure the backup vault, encryption type, backup cycle, and retention period. Cloud Backup starts the backup plan and continuously backs up files from the specified NAS file system.

    • You can enjoy a 30-day free backup plan for your first trial. You cannot edit the source path and backup cycle for a free backup plan.

    • We recommend that you include no more than 50 million files in each NAS backup job and no more than 8 million files and subdirectories in each directory.

    • After you create a backup plan, the first backup job performs a full backup and subsequent backup jobs perform incremental backups.

    • If the region that you select supports backup policies, you can set a backup plan only by associating it with a backup policy. Cloud Backup periodically backs up NAS file systems based on the backup policy.

    • To view the regions that support backup policies, click Policy Center in the left-side navigation pane of the Cloud Backup console. For more information about how to create a backup policy, see Create a backup policy.

  3. Restore a NAS file system

    If an exception occurs in a NAS file system, you can restore data to the source NAS file system or a new NAS file system that resides in the same region as the source NAS file system. You can also restore data to a new NAS file system across regions by using a remote mirror vault. You are charged for the traffic and storage capacity of the remote mirror vault.
