Sort of a poor man's rsync, that while less +efficient and awesome, is going to work on *every* remote that gets the new +chunking interface, from S3 to WebDAV, to all of Tobias's external special +remotes! Even allows for things like starting a download +from one remote, interrupting, and resuming from another one, and so on. + +I had forgotten about resuming while designing the chunking API. Luckily, I +got the design right anyway. Implementation was almost trivial, and only +took about 2 hours! (See [[!commit 9d4a766cd7b8e8b0fc7cd27b08249e4161b5380a]]) + +I'll later add resuming of interrupted uploads. It's not hard to detect +such uploads with only one extra query of the remote, but in principle, +it should be possible to do it with no extra overhead, since git-annex +already checks if all the chunks are there before starting an upload. |
