Mirroring is a nice thing when we think of migrating/moving big repositories considering the administrative tasks and the side effects involved. Right now, the SCM-Manager provides the facility to mirror any type of repository. But if it fails in between for whatever the reason is, it would not start/continue syncing because SVNSYNC has to be called with `--allow-non-empty` switch. I am not sure about the equivalent switch in SVNKit but this is a missing piece. With big repositories, if the sync stops in between, then removing it and restarting it from the scratch is not a workable approach. So please enable/facilitate `--allow-non-empty` option in SVN mirror page and make sure to set this property to the SVNPROPS of the target SVNREPO before calling the `SVNSYN SYNC file:///repositories/mysvnrepo` function. ![image](https://europe1.discourse-cdn.com/flex013/uploads/cloudogu2/original/1X/944305989b4eff70c2b321a9de279bf10d9b7bda.png) ---
