• If a computer is restarted when a device is in the disable state (which prevents the device
from being recognized by the OS), a backup using VSS after computer startup may fail.
Register the iSMvss_clear command (with no option) to the task scheduler so that it is
executed at computer startup.
• Unnecessary device entry information accumulates when a backup using VSS is
repeated.
If the amount of such information increases, the OS may fail to recognize Plug and Play
devices. Execute the iSMvss_clear delete command after performing a backup using VSS.
