It may make sense with something like rsync, using its
--partial and --compare-dest options. See the following from the
rsync documentation:
--compare-dest=DIR
This option instructs rsync to use DIR on the des
tination machine as an additional directory to com
pare destination files against when doing transfers
if the files are missing in the destination direc
tory. This is useful for doing transfers to a new
destination while leaving existing files intact,
and then doing a flash-cutover when all files have
been successfully transferred (for example by mov
ing directories around and removing the old direc
tory, although this skips files that haven´t
changed; see also --link-dest). This option
increases the usefulness of --partial because par
tially transferred files will remain in the new
temporary destination until they have a chance to
be completed. If DIR is a relative path, it is
relative to the destination directory.
You could use these features to synchronize files as much as possible
(even partial file transfers) over a slow link, without damaging the
"last known good" version. When a complete, newer version has been
trasferred, it can be dropped in place of the previous "known good"
version.
