Windows 2008 R2 Jenkins 1.509.4
Description
After upgrading to 1.509.4 our Maven builds create files that Windows cannot backup. The invalid files are SYMLINKD one for each module.
The maven build and UI seem to work fine. The files are under the jobs/project name/builds/buildnumber or builddate directory.

Jesse it is not the build number links that are problematic. The Maven build includes a section called Module Builds. The plugin seems to create a link for each Module. These module links are the problem. The Windows OS does not see the links as valid. I believe the links contain a path and the path uses the wrong path separator for Windows. I do not see any impacts in the Jenkins UI. I Jenkins is not impacted because Jenkins uses Java and Java can handle either Windows or Unix file separators. The problem is the Windows OS and backup software see these as corrupted files. Hope this helps.

added a comment - Hi there, i still hope that there will be some Progress on this Issue as this Problem is a real Blocker for Windows backed Jenkins Installations with Maven Projects.
Backups via ZIP/TAR and also Job Migration via copy of Jobs Folder to different Host is not working at the moment due to wrong generated symbolic links.

added a comment - Thomas we ended up excluding the build folders from our backups. Would like to see this resolved and be able to do a complete Jenkins backup.

added a comment - Our Jenkins Instance is growing and we would like to move from VM to Hardware. This Bug makes it impossible to transfer the Jobs to the new Instance without Data loss.

First of all, I doubt this has anything to do with the Maven plugin. Jenkins core creates build number symlinks.
Second, what is the actual bug here? That some old Windows backup programs cannot handle symlinks even when the Windows kernel/filesystem can produce them? That is the fault of the backup program, not Jenkins.
