# 1. Set the following MAIL and SERVERS variables.

# 2. Customize the RSYNC_INCLUDES and RSYNC_EXCLUDES variables.

# 3. Enable or disable local tasks inside the local_tasks() function.
|

# You must configure the MAIL variable to receive notifications.
|
||||
#
|
||||
# Some local tasks are configurable.
|
||||
# If you enable them, have a look at their implementation.
|
||||
# There is some optional configuration that you can do
|
||||
# at the end of this script.
|
||||
#
|
||||
# Some additional configuration variable can be customized
|
||||
# at the end of the script, before invoking the main() function.
|

# The library (usually installed at /usr/local/lib/evobackup/main.sh)
|

# also has many variables that you can override for fine-tuning.
