I'm using ProjectLocker with TortoiseSVN and VisualSVN.
Last night while trying to figure out a wierd issue, I reverted a couple files back to the last date that was in production. That happened to be about 3-4 revisions back.
When the older files didn't help the problem, I tried to do an update to get back to the most recent revision for the two files in question.
I see now (thanks to "Similar Questions") that I should have used Update to Revision instead of Revert.
The question is, can I get those revisions back somehow?
You should be able to revert to the revision before you reverted.
SVN doesn't directly support Rollback ("Revert" as tortoise calls it). Instead it takes a copy from the old revision and copies it over the new one.
But that still leaves the revision you were reverting away from in place. When you revert this time you may need to use a peg revision (eg for revision 123 you're reverting to http://mysvndomain.com/repos/foo/bar@123.
