I should clarify my question here.  Is there an issue with making sure
that the backed up BLOB directory is consistent with a particular backed
up state of the Data.fs via repozo.  IOW, can we say something like "so
long as you restore your BLOB directory to a state as it was in the same
moment or after the repozo process started then it is guataneed to be
consistent"?  I'm not saying that the above statement is correct cause I
don't know.  :) I'm just saying we'd need to be able to make some
promise about repozo backups of Data.fs and backups of BLOB directory
being consistent.
