How SVN work with large files?

Question

im working on UDK. The size of each map in UDK is around 200MB+ .

I had upload them to my SVN server.. But now i wants to commit those maps.

My Question is Whether my svn client upload those all maps again (200+MB again) or just changes on those maps(approx 15+MB).?

I read on this forum, but don't think, this'll also apply on large files. http://fluxbb.org/forums/viewtopic.php?pid=21182#p21182

Also Is it efficient to store large files in SVN, becoz if any set of data in a single file lost, then the whole file will be corrupt.

I am using TortoiseSVN Client

Thankx

Answer 1

If the content in your files in in text format and multiple lines then only the changed lines will be uploaded. That is efficient.

If it is a binary file, you have no benefit in using SVN since it is keeping copies of the whole file at commit.

Answer 2

I tried to commit a rar ball about 8 MB to my svn server, then add a small file to the rar ball, in my second commit I'm sure it just upload the changes, not the whole file.

So, although it is a binary file, TortoiseSVN can only upload the 15 MB changes, not ur whole 200 MB file.
