SQLserver restore with rename/relocate failing (4047641)

Title: SQLserver restore with rename/relocate failing
Date: 12/06
NV Version: all
OS Version: all
Application version: MS SQL
Plugin version: <4.5

Description:
A restore that consists of multiple files in an SQL file group or where the path is long will fail with Child Process Died. This is because there is a limited amount of space in the buffer for the restore command, and if the total required command exceeds this available buffer space, the plugin crashes. A straight restore back to the original location succeeds

This has been identified as a problem with the length of the rename/relocate buffer, an overrun happens due to the number of files or total path length, thus causing the process to quit unexpectedly. This will only occur when attempting a restore that requires the SQLserver data files to be relocated to a new name or location and via the move command

Symptoms:
