Assume an SVN setup that consists of a single repo with nested project folders, something like this:
\ - trunk - - projectA - - - trunk - - - - ... - - - branches - - - - ... - - projectB - - - trunk - - - - ... - - - branches - - - - ... - ...
The whole repo is about 40GB on disk, with 17605 commits at last count. I now need to extract a single project from the repo to setup on a separate SVN server, which I understand is possible only by using
svnadmin dump on the entire repository and then using
svndumpfilter to isolate the project that I need. I fully expect that this will take a really long time to complete the initial dump. Is there a good formula for calculating exactly how long it will take and how much disk space will be required for the final dump file? Also, I've heard that the dump operation uses 100% CPU while it runs. Is that true?
Alternately, is there a better way to go about this given the size of the repo? (Other than just doing an export and losing the revision history.)
