I forgot to say that scripts.Thu-29-Jul-2010.tgz.bf it is generated in
a different way of dump files:
guardassl() {
if [ "$2" != "" ];then
EXCLUDE="--exclude \"$2\""
fi
logstr "guardando $1 con blowfish $EXCLUDE"
ARCH=`echo "$1" | sed 's/^\///'|sed 's/\//./g'`.$DATE.tgz.bf
tar --create --preserve --gzip $EXCLUDE $1 | openssl bf -out $ARCH
-k $KEY 2>> $LOGFILE
return $?
}
