And how many times did you accidentally delete files from svn repo - be it because you were copying and instead moved, typo’d and deleted 1 file instead of another or for whatever reason?!
Easiest to do: simply copying the file from elsewhere and svn add
Better way to do: restore the files, including the svn history.
To see which revision deleted the file, foo.file
1 2 3
Now copy the file from the previous revision using the repo url, not just the location on the local machine
1 2 3 4 5 6
And now the svn log still shows the entire history without the deletion
