    OK, I blew away my deduplication folder and made it a Backup to Disk folder.  I have lots of space and will just keep the last couple of months on disk.  That will solve my space problem and I'll be able to restore to disk quickly if the request is for reasonably recent data.  An upgrade is in the works.

When you use dedup, it is not a simple "overwriting the media".  The underlying process is a lot more complicated than that.  Do read my articles below for a good understanding of the dedup process.

You can try to force a space reclaim of the dedup folder using the procedure below

How much free space is there on the volume on which the dedup resides?  Is the volume shared with other applications?  It is recommended that the dedup folder has exclusive use of the entire volume on which it resides.

If the disk is full, you might need to move it to another volume with more space.  Use the procedure in the document below
