Here are two recommended approaches for copying data between instances running in the two clouds. The most appropriate method depends upon the size of the data volumes in your tenant. For very large volumes (e.g. greater than 5TB) Globus is recommended. Please see here for configuration details: [https://computecanada.github.io/DHSI-cloud-course/globus/ https://computecanada.github.io/DHSI-cloud-course/globus/] | |||

For volumes | For smaller volumes, rsync+ssh provides good transfer speeds and can (like Globus) work in an incremental way. A typical use case would be: | ||
# SSH to the West Cloud instance which has the large volume attached | # SSH to the West Cloud instance which has the large volume attached. Note the absolute path you want to copy to the instance on Arbutus Cloud. | ||
# Execute rsync over SSH | # Execute rsync over SSH. The example below assumes that password-less login via [[SSH keys]] has already been setup between the instances. Replace the placeholders below with real values: | ||
#: <code> rsync -avzP -e 'ssh -i ~/.ssh/key.pem' /local/path/ remoteuser@remotehost:/path/to/files/ </code> | #: <code> rsync -avzP -e 'ssh -i ~/.ssh/key.pem' /local/path/ remoteuser@remotehost:/path/to/files/ </code> | ||
