Automatic rsync retry with incremental (delay) backoff
# Rsyncr (Rsync Retry) 2016 David Mcanulty
# Runs rsync, retrying on errors up to a maximum number of tries with incremental backoff (delay)
# Based on idea from by iangreenleaf 2011
# Set your max rsync retries here
# Trap interrupts (ctrl-c) and exit instead of continuing the loop
# This restarts the agent every 30 days, to make sure its not hung
# And also checks that the lockfile isn't more then 1 hour old
check process puppet with pidfile /var/run/puppet/
group system
start program = "/usr/sbin/service puppet start"
stop program = "/usr/sbin/service puppet stop"
if 5 restarts within 5 cycles then timeout
if uptime > 30 days then restart
