After the fix done in EZP-24692 the same issue remains on a DFS cluster.

Duplicate files are being created (for instance on ezpublish_legacy/var/cluster/var/ezdemo_site/storage/original/video/) on each autosave, and are never removed.

Steps to reproduce:

1) Go to media library.
2) Create object of class video.
3) Upload a video (do it before defining a name so that autosave will be called several times)
4) Set a name
5) Set a caption and leave the field. At this time the video is stored 3 times in the file system.
6) Publish the object. Now 4 files are stored in file system.
7) Remove the object. The files created in duplicate (different hash name but same content) are still on the server.
