| Hi All.
| I currently have a problem on my backup server with very large number
| of
| small files in a large number of directories. I would like to delete
| them
| as fast as possible. Currently I use:
| rsync -a --delete /empty_directory/ dir_to_clean/
| I've read that rsync will be faster than rm or find.
| Can you recommend something? I use an ext4 filesystem.
| Best regards,
| Rafal.

If it's on a different file system than mkfs is the fastest. ;)
