Você poderia tentar usar wget -c
:
-c
--continue
Continue getting a partially-downloaded file. This is useful when you
want to finish up a download started by a previous instance of Wget, or
by another program. For instance:
wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z
If there is a file named ls-lR.Z in the current directory, Wget will
assume that it is the first portion of the remote file, and will ask the
server to continue the retrieval from an offset equal to the length of
the local file.
