Package: rsync
Version: 3.0.7-2
Severity: normal
Hi,
With experience, I noticed several time that rsync is not robust. (Trust me).
If you take a pendrive for instance, it can do not like rsync -avr ...
if you take weird partition and format of files, or lengths... rsync can miss
some files , and cp -r -u is really much much much more robust.
OK. it is not the point to make rsync better, since it is likely to be tested
with all kind of partition format (vfat, ext3, ...) and filenames, dir
depths,...
I would recommend you cp -r -u, it is much more performant, .. ok, but
sometimes we really need to use rsync
what to do? how to verify?
I would propose to add a switch to verifiy that rsync copy well. We deal here
about gb or tb or servers of data, so rsync shall not be a joke by the end
here an example of script:
#!/bin/sh
# /usr/bin/ducompare
# basic minimalistic rsync code checker
# coded by frenchn00b
CURRENTDIR=` pwd `
DIRSRC="$1"
DIRTRGT="$2"
if [ ! -d "$DIRSRC" ] || [ ! -d "$DIRTRGT" ] ; then
echo "Not directories"
echo "Exit"
exit
fi
DIRSRCSTR=` basename "$DIRSRC" `
DIRTRGTSTR=` basename "$DIRTRGT" `
if [ "$3" != "-checksrc" ] && [ "$3" != "-checksrcs" ] ; then
#echo " $DIRSRC $DIRTRGT"
#printf "__STAT_"
printf "%*s" 15 "Stat"
printf "%*s" 15 "$DIRSRC"
printf "\t"
printf "%*s" 15 "$DIRTRGT"
printf "\n"
ls -1 "$DIRSRC" | while read -r i ; do
SIZEDIRSOURCE=` du -hs --apparent-size "$DIRSRC/${i}" | cut -f 1 `
if [ -d "$DIRTRGT/${i}" ] ; then
SIZEDIRTARGET=` du -hs --apparent-size "$DIRTRGT/${i}" | cut -f
1 `
else
SIZEDIRTARGET="not found"
fi
if [ "$SIZEDIRSOURCE" = "$SIZEDIRTARGET" ] ; then
TESTVAL="OK"
else
TESTVAL="NOT_OK"
fi
#printf "$TESTVAL"
#printf "\t"
printf "%*s" 15 "$TESTVAL"
printf "%*s" 15 "$SIZEDIRSOURCE"
printf "\t"
printf "%*s" 15 "$SIZEDIRTARGET"
printf "\t\t$i"
printf "\n"
done
fi
if [ "$3" != "-hide" ] ; then
echo "--- Reverse check ---"
#echo "Check the possible target missing directories"
ls -1 "$DIRTRGT" | while read -r i ; do
FILET="$DIRSRC/${i}"
FILETT="$DIRTRGT/${i}"
if [ ! -d "$FILET" ] && [ ! -f "$FILET" ] ; then
SIZEFOL=""
SIZEFOLSTRING=""
if [ "$3" = "-checksrcs" ] ; then
SIZEFOL=`du -hs "$DIRTRGT/${i}" | cut -f 1 `
SIZEFOLSTRING="(${SIZEFOL})"
fi
printf "%*s" 15 "SRC NOT OK"
printf "%*s" 15 "not found"
printf "\t"
printf "%*s" 15 "$SIZEFOLSTRING"
printf "\t\t${FILETT}"
printf "\n"
fi
done
fi
For the swtich checker, ... creativity ;)
Enjoy Linux
many thanks
