* ahem. Revision is always a revision in SVN. It’s rN and all commands accept it.

* ahem. All branches in SVN are copies of an existing tree at a particular revision. Call it a branch or whatever you want. But if you make a copy of your main development tree, you make a branch and you can work on it in the same fashion as if it was git. Merge it back to trunk when done or continue your work and sync with trunk or other branches. The principle is the same.

* Failing “svn up” is an unexpected technical problem that occurs due to problems with the server or network. The problem should never happen in normal cases.
