I run VMWare Fusion which uses a large file, about 54GB. I needed to revert to an older version of the file so I deleted the bad one, mounted an external drive with a good version of the file, and used the Finder to try to drag and drop to copy it. This failed with a message from the Finder there isn't enough space. However, according to the Finder there is 84GB of space available on the destination. I've rebooted multiple times and used Disk Utility to repair permissions and verify the destination is ok. No errors. I checked the Console and there I see the messages I've pasted at the bottom. Doing some searching I found this quote in a Support article:

Note: You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. Those differences are expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.

 

Based on the below log, it seems the agent is unable to free up the space. Any idea how to repair this? It looks like, even though this large file is excluded from Time Machine backups, that TM has created a local copy and now can't delete it. I'm running 10.8.5 on a MBAir 13". Thanks.

    You can't back up virtual disk files reliably or efficiently. They won't be backed up at all while open, and when closed they'll quickly fill up any backup volume. You should exclude them from backup by Time Machine and instead back up the contents in the guest system, using a native backup tool.

    From the menu bar, select

        

     ▹ System Preferences ▹ Time Machine

      

    If the padlock icon is closed, click it to unlock the settings and authenticate. Turn Time Machine OFF, then turn it backON and close the preference pane. Test.

    Ron, I had this issue as well when transferring VM images between two disks. Both the source and destination are excluded from time machine but this process quickly bloated the local "backup" area on my drive.

     

    I think the lack of consistency between what the system report shows as your disk usage and what finder reports is appalling. Turning off time machine, waiting to see the reclaimspaceagent run and then re-checking the disk usage in system report showed these local backups were properly removed.
