How to migrate existing files to Amazon FSx using rsync

With rsync, you can replicate data between any source and destination, but at least one must be locally accessible to the client instance.

To migrate existing files to Amazon FSx from a Linux-based Amazon EC2 instance

The following procedure configures your FSx for OpenZFS destination volume as a local NFS mount on a Linux-based EC2 instance and uses the rsync command to synchronize data from your source file system or existing directory on your EC2 instance.

1. Launch a Linux-based Amazon EC2 instance or connect to an existing EC2 instance that contains your desired source data.

2. Mount your destination FSx for OpenZFS source volume; for more information, see Mounting FSx for OpenZFS volumes to Linux clients. The following step assumes that you have mounted your desired destination on your OpenZFS volume to /fsx/destination_path on your EC2 instance.

3. Run rsync from this EC2 instance to synchronize data from your source. If your source data is already on the EC2 instance, use the following command:

   sudo rsync -avR /source_path /fsx/destination_path

   Note

   You can also run rsync with GNU parallel to maximize performance. The following instructions apply for EC2 Linux instances running Amazon Linux 2:.

   sudo amazon-linux-extras install epel 
   sudo yum install nload sysstat parallel -y
   sudo time find -L /source_path -type f | parallel rsync -avR {} /fsx/destination_path

   If your source is a directory on a remote host, use the following command:

   sudo rsync -avR username@source_dns_or_ip:/source_path /fsx/destination_path

   Use the following variant if you need to use .pem key-based authentication:

   sudo rsync -avR -e "ssh -i key.pem" username@source_dns_or_ip:/source_path /fsx/destination_path

To migrate existing files to Amazon FSx from your on-premises Linux-based source

The following procedure configures your FSx for OpenZFS destination volume as a local NFS mount on a Linux-based EC2 instance. Then, you use rsync from your source to connect to this EC2 instance and synchronize files to the path where the destination Amazon FSx volume is mounted.

1. Launch a Linux-based Amazon EC2 instance and mount your destination FSx for OpenZFS source volume. For more information, see Mounting FSx for OpenZFS volumes to Linux clients. The following step assumes that you have mounted the desired destination on your OpenZFS volume to /fsx/destination_path on your EC2 instance.

2. From your on-premises Linux-based source, run rsync to connect to this EC2 instance and synchronize data from any locally accessible path. For example, source_path can refer to a locally accessible directory or a path on another shared file system.

   sudo rsync -e "ssh -i key.pem" /source_path ec2-user@ec2_dns_name.amazonaws.com:/fsx/destination_path
