how to transfer Time machine data from NAS to USB drive so that it can be restored from?

I backed up my old mac mini (2011) using Time machine to a NAS over SMB. Now I'd like to restore the mini from the backup, however the SMB mount is not accessible from the Recovery mode (at least on OS X Lion, as also referenced on https://apple.stackexchange.com/questions/122389/mounting-smb-network-share-from-mavericks-recovery-mode?rq=1) and I cannot easily reconfigure the NAS share to use AFP. Nevertheless, I can login into the NAS using SSH and I can see the files:

nas% ls /mnt/uloziste/macbackup/mini/vladak/
.apdisk                           .DS_Store                         Vladimir’s Mac mini.sparsebundle/ 
nas% ls /mnt/uloziste/macbackup/mini/vladak/Vladimir’s\ Mac\ mini.sparsebundle/
bands						com.apple.TimeMachine.Results.plist		Info.plist
com.apple.TimeMachine.MachineID.bckup		com.apple.TimeMachine.SnapshotHistory.plist	token
com.apple.TimeMachine.MachineID.plist		Info.bckup

How do I transfer these files to a USB drive (formatted as Mac OS Extended) so that the Recovery mode will recognize it as a Time machine drive and will be able to recover from it ?
