I should add that the simplest way to back up a directory is to
specify it as an operand to the dsmc Incremental command, which can be
achieved via a separate client schedule, where the directory name(s)
would be specified via the OBJects parameter, and use the OPTions
parameter for things like "-SUbdir=Yes".

You could achieve the same effect by defining /root as a
VIRTUALMountpoint and then specifying that in DOMain, but I would not
generally recommend that, as it artificially makes the directory a
filespace separate from its natural parent, which can make recoveries
less obvious.
