# Exclude trailing slash!

# Your EXCLUDE_FILE tells rsync what NOT to backup. Leave it unchanged, missing or
# empty if you want to backup all files in your SOURCES. If performing a
# FULL SYSTEM BACKUP, ie. Your SOURCES is set to "/", you will need to make
# use of EXCLUDE_FILE. The file should contain directories and filenames, one per line.
# An example of a EXCLUDE_FILE would be:
# /proc/
# /tmp/
# /mnt/
# *.SOME_KIND_OF_FILE
EXCLUDE_FILE="/root/bin/rsync-exclude.txt"
