I like to keep everything backed up with version control because it makes everything easier in the long run. I frequently run into problems with other people screwing up svn and I get stuck fixing what is going on when the cron jobs break that automagically back stuff up. After some research and combinging others efforts I came to this command that adds everything not currently added to svn. It also deals with spaces in the file names.
svn status | awk '/\?/' | sed 's/\? *//g' | sed 's/ /\\ /g' | xargs svn add
output the status of files in the current folder, if you don't understand this part, you probably shouldn't go any futher :)
find all lines that have a ?, aka they have not been added to svn yet
further strip down the line to remove the ? mark, leaving the path only
convert spaces in path to one that is escaped.
take each line and pass them as the last argument to svn add
