I love using ROBOCOPY to perform my file backups but just after DAYLIGHT SAVINGS TIME occurs it appears to no longer perform a DIFFERENTIAL backup. Instead, ROBOCOPY starts copying as if it were the very first time. I know there is a 'DST' optional flag available but when using it, DST appeared to have no influence on the execution (i.e., it still treats my copy as if it were the very first time). This adds a lot of time since my ROBCOPY has many files in many subdirectories.
So my questions are:
1) why does DAYLIGHT SAVINGS TIME force ROBOCOPY to start as if it had never performed a copy on my files before?
2) what is the purpose of the DST flag?
3) how can I get ROBOCOPY to treat copying my files the same way as if DAYLIGHT SAVINGS TIME had not occurred?
