Amazon Elastic File System (EFS) | Data Protection and Availability Flashcards
How do I load data into a file system?
Data Protection and Availability
Amazon Elastic File System (EFS) | Storage
There are a number of methods for loading existing file system data into Amazon EFS, whether your existing file system data is located in AWS or in your on-premises servers.
Amazon EFS file systems can be mounted on an Amazon EC2 instance, so any data that is accessible to an Amazon EC2 instance can also be read and written to Amazon EFS. To load file data that is not currently stored in AWS, you can use EFS File Sync to copy data directly to Amazon EFS.
For on-premises file systems, EFS File Sync provides a fast and simple way to securely sync existing file systems into Amazon EFS. EFS File Sync works over any network connection, including with AWS Direct Connect. AWS Direct Connect provides a high bandwidth and lower latency dedicated network connection, over which you can mount your EFS filesystems. You can also use standard Linux copy tools to move data files to Amazon EFS.
For more information about accessing a file system from an on-premises server, please see the On-premises Access section of this FAQ.

How is Amazon EFS designed to provide high durability and availability?
Data Protection and Availability

Every file system object (i.e. directory, file, and link) is redundantly stored across multiple Availability Zones. In addition, a file system can be accessed concurrently from all Availability Zones in the region where it is located, which means that you can architect your application to failover from one AZ to other AZs in the region in order to ensure the highest level of application availability. Mount targets themselves are designed to be highly available.
How do I back up a file system?

Amazon EFS is designed to be highly durable. Using the EFS-to-EFS Backup solution, you can schedule automatic incremental backups of your Amazon EFS file system. For more information, please see the Amazon EFS Walkthrough: Backup Solutions for Amazon EFS File Systems.
