How to get files from a hung server using rescue-system and ssh?

Question

SSH

The server running Window Server 2008 R2 is frozen and not responding to higher connections. The server is hosted by Hetzner. They provide a rescue-system to choose from Linux, FreeBSD, OpenSolaris, vKMV. Ok, downloaded Linux, launched it, logged in via SSH. Now I don't know what to do next.
The Hetzner wiki ( link ) says that to access data from a disk, you need to run the commands:
cd /mnt
mkdir rescue
mount -o ro /dev/md2 /mnt/rescue
or
mount -o ro /dev/sda3 /mnt/rescue I did it, I
got an error:
you must specify the filesystem type
I'm not a system administrator, I ask for help, how can I get all these to the data on the disk?

Answer 1

Asks you to specify the type of file system on the disk you are mounting.
Try fdisk -l /dev/sda3 to see the file system type.
Or mount as ntfs:
mount -o ro -t ntfs /dev/sda3 /mnt/rescue

Answer 2

# mount -t ntfs -o ro /dev/sda3 /mnt/rescue
# mount -t ntfs-3g -o ro /dev/sda3 /mnt/rescue
next:
# scp -r /mnt/rescue [email protected]: /tmp
still needs to be clarified about /dev/sda3 ... what if sda2?
# fdisk -l

Answer 3

I did according to the instructions , I did not see any problems.
