SSH Transfer Files Using tar

tar can be used to fast transfer files between two Ubuntu servers.

Push Directory from Server A to Server B (same path)

The following files/directories in Server A will be excluded:

sudo tar -c {{ path.value }} | ssh {{ b_hostname.value }} 'sudo tar -xvf - -C /'

parallel by directories (same path)

sudo apt install parallel
find {{ path.value }} -type d -maxdepth 1 | parallel --will-cite --dry-run -j {{ job.value }} sudo tar -c {} \| ssh {{ b_hostname.value }} 'sudo tar -xvf - -C /'
find {{ path.value }} -type d -maxdepth 1 | parallel --will-cite -j {{ job.value }} sudo tar -c {} \| ssh {{ b_hostname.value }} 'sudo tar -xvf - -C {} -C /'

不需要
find {{ path.value }} -type d -maxdepth 1 | parallel --will-cite -j {{ job.value }} ssh {{ b_hostname.value }} 'sudo mkdir -p {}'
