Restoring an archive from backup, and then?

Hello!
Our SVN server had a disk failure and some projects had to be restored from the nightly backup.

What happens in such a case, if my working copy is on revision 120 and the latest revision in the restored archive is 110?

I did some tests and it looks like subversion detects that (I used TortoiseSVN 1.7.10 on windows using the svn core library 1.7.7).
So at least it looks like a newer working copy can not be overwritten incidentially by the restored (older) HEAD revision.

But how should one recover in such a situation?
Is a fresh checkout and a manual merge necessary?

Mit freundlichen Grüßen
