![]() ![]() Now that the agent is running and activated, I click on Create sync task to start moving some files to EFS: After it completes, I enter a name for it and click Activate agent to proceed: This step retrieves the activation key from the sync agent. Then I capture the instance’s public IP address, return to the EFS tab, enter the address, and click on Activate agent: Then I wait a minute or two (time to water my plants or check on my dog), and wait until the status checks pass: I pick a Memory optimized instance type ( xlarge or bigger), configure it with a public IP address and with a security group that allows inbound traffic on port 80, and launch it as I would any other EC2 instance. I click on Get started, choose Amazon EC2 as my host platform and click Launch instance, and click Connect to agent to proceed:Ĭlicking Launch instance opens the EC2 console in a separate tab. I open the EFS Console in the same Region as my instance, and click File syncs: In order to write this blog post, I launched an EC2 instance, exported an NFS file system ( /data), and populated the file system with the Linux kernel source code. File metadata (modification and access time, POSIX ownership and permissions, symbolic links, and hard links) is also copied. Jobs can specify the transfer of an entire file system or a specific directory tree, with the option to detect and skip files that are already present in the destination. You can launch, control, and monitor the agent and your sync tasks from the AWS Management Console. Because the agent is responsible for initiating all communication with AWS you don’t need to set up VPNs or allow inbound connections through your firewall. ![]() It is available as an agent that runs within VMware ESXi or on an EC2 instance, and accesses the source file system via NFS (v3 and v4), and can be used in all AWS Regions where EFS is available. Secure & ParallelĮFS File Sync uses a secure, highly parallel data transfer mechanism that can run up to 5 times faster than the tools I mentioned above. These tools are generally used as building blocks, often within scripts that take care of scheduling, orchestration, and network security. Simple, single-threaded command line tools such as cp and rsync predate the cloud and cannot deliver the throughput required to move massive amounts of data from place to place. With folder-level encryption, all files in the folder are encrypted.If you need to move a large collection of files from an on-premises or in-cloud file system to Amazon Elastic File System, this tool is for you. If you are working with applications that create temporary files, you might want to enable encryption at the folder level instead of the file level in order to guard against unauthorized access to your temporary files. You can also enable or disable encryption from the command prompt using the cipher command. You can encrypt or decrypt a file or folder on an NTFS volume with the Advanced button on the General page of that file or folder’s property sheet. Have permission to share the encrypted file.Have the private key for the file (in other words, the file was originally encrypted by that user). ![]() To access an encrypted NTFS file, the user must meet one of the following criteria: EFS stores encryption keys in the nonpaged pool of memory. EFS encrypts this encryption key using the user’s public key. The user’s private key, stored in Active Directory, is used for decrypting encrypted files and folders.Įach time EFS encrypts a file or folder, it generates a random encryption key. EFS is simple to use and automatically generates an encryption key pair for the user who is logged on if one does not already exist. Encrypting File System (EFS) What is EFS (Encrypting File System)?Įncrypting File System ( EFS) is a public key cryptography scheme based on the Data Encryption Standard (DES) that runs as a Windows 2000 system service and is transparent to the user.
