- Create a new EFS file system to use as the backup target or use an existing one:
Log in to the AWS Management Console, navigate to the EFS service, and click on "Create file system."
Choose the region where you want to create the file system, and select the performance mode that meets your workload needs.
Configure the file system settings, including the file system name, VPC and subnets, and security group.
Click on "Create file system" to create the new EFS file system.
- Create a backup policy or modify an existing one:
Select the EFS file system that you want to back up from the EFS console.
Click on the "Backup policies" tab and then "Create backup policy."
Specify the backup frequency, retention period, and the EFS file system to be backed up.
Optionally, you can configure advanced settings such as the backup window, backup rule priority, and preferred backup time zone.
Click on "Create backup policy" to create the new backup policy.
- Associate the backup policy with the source EFS file system:
Select the source EFS file system that you want to back up.
Click on the "Backup policies" tab and then "Associate backup policy."
Select the backup policy that you created in step 2 and click on "Associate backup policy."
- Wait for the first backup to complete:
Monitor the backup status in the EFS console and wait for the first backup to complete.
The backup process may take several hours depending on the size of the file system.
Once the backup is complete, you can view the backup status, backup creation time, and backup ID in the EFS console.
- Monitor the backup status and any errors or warnings:
Navigate to the "Backup jobs" tab in the EFS console and monitor the backup status and any errors or warnings.
If any errors or warnings occur, view the backup job details to identify the root cause and take corrective actions.
- Restore a file system from backup:
Select the backup that you want to restore from the "Backups" tab in the EFS console.
Click on "Restore file system" and follow the prompts to create a new file system using the backup data as the source.
Configure the necessary mount targets and security settings for the restored file system.
Once the file system is restored, you can access the backed-up files and directories.
To summarize, taking a backup of AWS EFS involves creating a new EFS file system as the backup target, creating or modifying a backup policy, associating the backup policy with the source EFS file system, monitoring the backup status, and restoring a file system from backup.
