new: [rsync-backup] rewrite of mirror-dir

Includes ``mirror-dir-check`` with the ``mirror-dir check`` call, the
replacement of ``mirror-dir`` call is ``mirror-dir backup``. An additional
``mirror-dir report`` was added.

usage="usage: $exname -d DEST1 [-d DEST2 [...]] [-u USER] [DIR1 [DIR2 ...]]
Preserve as much as possible the source structure, keeping hard-links, acl,
exact numerical uids and gids, and being able to resume in very large files.
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
-u USER (default: 'rsync')
Local AND destination user to log as at both ends to transfer file.
This local user need to have a NOPASSWD ssh login towards it's
account on destination. This destination account should have
full permissions access without passwd to write with rsync-server
in the destination directory.
-h STORE (default is taken of the hostname file)
Set the destination store, this is the name of the directory where
the files will all directories will be copied. Beware ! if 2 hosts
use the same store, this means they'll conflictingly update the
same destination directory. Only use this if you know what you
are doing.

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:
$(

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,

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,
