The pscp
does not support resume.
As @PeterJ commented, an another tool from PuTTY suite, the psftp
, does. You should have no problems resuming interrupted pscp
transfer with psftp
:
C:\>d:\putty\psftp root@serverip psftp> reget /root/movie C:\movie reget: restarting at file position xxxxxx remote:/root/movie => local:C:\movie
