There is no in-memory backup: once a value is over-written, it's
gone.
However, gretl does keep a backup of the last-saved version of any
given datafile (in "native" format). Whenever you save changes to
(say) foo.gdt, a file foo.gdt~ (with trailing tilde) will be
written, holding the previous content of foo.gdt. If you need to
recover previous data, use your file manager to rename foo.gdt~.
