Interesting. /ZB has thus far escaped me, I'll give it a try.

From above:
/MT[:n] :: Do multi-threaded copies with n threads (default 8).
n must be at least 1 and not greater than 128.
This option is incompatible with the /IPG and /EFSRAW options.
Redirect output using /LOG option for better performance.
/E :: copy subdirectories, including Empty ones.
/ZB :: use restartable mode; if access denied use Backup mode.
/COPYALL :: COPY ALL file info (equivalent to /COPY:DATSOU).
/R:n :: number of Retries on failed copies: default 1 million.
/W:n :: Wait time between retries: default is 30 seconds.

What I use, with other flags as needed on a per command basis:

Well, my default command is this, I just edited it for the relevant bits of the post:

RoboCopy %Source% %Destination% /MIR /XA:SH /MT:20 /E /ZB /COPYALL /R:1 /W:1 /NS /NC /NP /NFL /NDL /LOG+:%LogFile%

set RCOPTIONS1=/MIR /Z /R:2 /W:5
set RCOPTIONS2=/NFL /NDL

REM /MIR :: MIRror a directory tree (equivalent to /E plus /PURGE).
REM Requires BOTH /NFL /NDL to make it quiet!
REM /Z :: copy files in restartable mode.
REM /R:n :: number of Retries on failed copies: default 1 million.
REM /W:n :: Wait time between retries: default is 30 seconds.
REM /NFL : No File List - don't log file names.
REM /NDL : No Directory List - don't log directory names.
REM /J :: copy using unbuffered I/O (recommended for large files).

Thanks,
JP
