usage="usage: $exname -d DEST1 [-d DEST2 [...]] [DIR1 [DIR2 ...]]
Checks that mirror-dir did it's job. Will send an email if not.
Options:
DIR1 ... DIRn
Local directories that should be mirrored on destination(s).
examples: /etc /home /var/backups
If no directories are provided, the config file root
entries will be used all as destination to copy.
-d DESTn
Can be repeated. Specifies host destination towards which
files will be send. Note that you can specify port number after
a colon and a bandwidth limit for rsync after a '/'.
examples: -d liszt.musicalta:10022 -d 10.8.0.19/200
-n TIME_SPEC
Give a full english time spec about how old the last full
run of rsync should be at most. Defaults to '12 hours'.
examples: -n '12 hours'

Hi,
Some configured mirroring targets have not finished gracefully in
the last $time_spec. Please see for yourself:
$(
for m in "${msg[@]}"; do
echo " $m"
done
)
You might want to find these following information of some use:
$(
for m in "${bad_sessions[@]}"; do
if [ -e "${state_dir}"/$m-fail ]; then
echo " ${sessions[$m]}:"
tail -n 5 "${state_dir}"/$m-fail | cut -f 1,2,5- -d " " | sed -r "s/^/ /g"
echo
else
echo " ${sessions[$m]}: no fail log available"
fi
done
)
Hoping all this will help you sort out the issue...
Yours sincerly,
