## This is the main Core Rsync script

|
|
# User variables can be adjusted in Master.conf
|
|
# Scripts now just contain runtime logic
|
|
#
|
|
# This allows for profiles and multiple things to use the core script
|
|
# Use arguments in unRAID User Plugin for directory
|
|
# Example: /mnt/user/appdata/unraid_scripts/Rsync/rsync.sh /mnt/user/appdata-test/Arrs/
|
|
#
|
|
# /mnt/user/appdata-test/Arrs/ is the argument
|
|
# If the last name /Arrs/ matches a profile in Master.conf, then profile defaults are used
|
|
# Otherwise, global configuration in Master.conf is used
