Please use below script to get existing backup version details from target volume,
import os;
import ctypes;
volume='E';
class disable_file_system_redirection:
_disable = ctypes.windll.kernel32.Wow64DisableWow64FsRedirection
_revert = ctypes.windll.kernel32.Wow64RevertWow64FsRedirection
def __enter__(self):
self.old_value = ctypes.c_long()
self.success = self._disable(ctypes.byref(self.old_value))
def __exit__(self, type, value, traceback):
if self.success:
self._revert(self.old_value)
with disable_file_system_redirection():
version=os.popen('wbadmin GET VERSIONS -backupTarget:'+volume+':').read();
print(version);
Sample output would be as below,
