# this script should run as the 'git' user, not root, because 'root' should not
# own intermediate directories created by rsync.
#
# Example invocation:
# find /var/opt/gitlab/git-data/repositories -maxdepth 2 | \
#   parallel-rsync-repos transfer-success.log /var/opt/gitlab/git-data/repositories /mnt/gitlab/repositories
#
# You can also rsync to a remote destination.

# parallel-rsync-repos transfer-success.log /var/opt/gitlab/git-data/repositories user@host:/mnt/gitlab/repositories

# If you need to pass extra options to rsync, set the RSYNC variable
#
# env RSYNC='rsync --rsh="foo bar"' parallel-rsync-repos transfer-success.log /src dest
