Restore individual SQL databases with ease

Veeam Explorer for Microsoft SQL Server delivers an easy-to-use, wizard-driven interface for restoring your databases from a backup. No expert SQL background required. Web interface provides a complete view of all available SQL databases to simplify the recovery of lost database

Here's a simple script that uses the "itemize" function of rsync to tell you which files have changed, and put those in a seperate dated folder, which is what I think you were requesting:

#!/bin/sh

STAMP=`date +%Y%m%d-%H%M%S`

SRC="sourcefolder"
DST="destfolder"
CHG="$DST/$STAMP"
OUTPUT="rsync.out"

rsync -avi $SRC $DST > $OUTPUT

for CHANGE in `grep ^\>f $OUTPUT | awk '{print $2}'`;
do
        if [ ! -d $CHG ]; then
                mkdir $CHG
        fi
        cp -v $CHANGE $CHG
done

rm -f $OUTPUT

Here you go, modified to use tar instead of cp so it will create the directories in the structure you requested:

#!/bin/sh

STAMP=`date +%Y%m%d-%H%M%S`

SRC="sourcefolder"
DST="destfolder"
CHG="$DST/$STAMP"
OUTPUT="rsync.out"

rsync -avi $SRC $DST > $OUTPUT

for CHANGE in `grep ^\>f $OUTPUT | awk '{print $2}'`;
do
        if [ ! -d $CHG ]; then
                mkdir -p $CHG
        fi
        (tar cpf - $CHANGE ) | (cd $CHG && tar xvfp -)
done

rm -f $OUTPUT
