please define what "backup a file constantly" means for you.
does it mean: having an exact _current_ copy all the time on two storage
systems (i.e. safety against "disaster")
does it mean: keep a historic change log of the file for every change
made, with the ability to rollback to any desired state?
does it mean: keep a backup of the file every 10 minutes?
does it mean something else?
then define: the size of the file (min/average/max)
the rate of changes per time unit (min/average)
who generates the file and changes to the file - a given
software you wrote, a given software you did not write?
are the changes to the file performed manually, or by
automatic software?
then come back.
