What program to use for incremental backup of large single file

Question

I'm looking for a program to make incremental backups of one large file (3GB) on windows systems over internet.

Any idea? Thanks!

Answer 1

If you just want to keep a remote copy of the file then using something based on rsync will probably work for you. Rsync only copies the parts of the file that have changed so it can reduce the amount of data you have to to copy.

For windows you could use deltacopy or syncrify.

Answer 2

you can also give rdiff-backup a try. it has version for windows too.

i use it for nightly backups of [in total] few hundreds GB of data.

Answer 3

I suggest rsync. It's the standard tool for this sort of thing, and I gather it works on Windows as well.
