There is no one large file. As I wrote, restored backup is not so large too.
But you pointed me to right plate. I see this line in XferLOG:
new recv hf..tpog... rw-r--r-- 1000, 1000 25089367
var/www/public/media/598522/catalogue.pdf =>
var/www/private/import/docs/catalogue.pdf
This is a symlink and it's size is counted as 25089367.
According to "=>" symbol, this symlink is properly identified as symlink,
but it's size is stored as symlinks target file. This is why backup
size is larger than my filesystem. Can this be fixed?
