Здравствуйте!
Имеется скрипт для резервной копии:
#!/bin/sh
date=`date "+%Y-%m-%d-%H%M%S"`
SRC="/home/source/" #sdc1 hdd
DST="/home/distance/" #sdd1 hdd
rsync -a --delete --link-dest=$DST/latest $SRC $DST/proc-$date
cd $DST
mv proc-$date $date
rm -f $DST/latest
ln -s $date $DST/latest
обратил внимание очень долго горит лампочка обращения к диску, расставил echo,

Два-три часа допускаю, но двенадцать кажется перебор. Размер каталога около 130GB. В чем может быть проблема и можно ли что поправить. Предполагаю или с жесткими ссылками тормозит, или все перезаписывает, но объем диска уходит адекватно. Изменений происходит 0.5-1% от объема.
