Media set free space seems incorrect after groom operation


Recommended Posts

After completing a groom operation, the log shows:

 

Executing Groom OWC at 7/14/15, 12:27:00 PM

Grooming Media Set OWC Backup...

Groomed 29.9 GB from Media Set OWC Backup.

7/14/15 1:12:00 PM: Execution completed successfully

Completed: 52,074 files, 29.9 GB

Performance: 681.7 MB/minute

Duration: 00:44:58

 

It looks like 29.9GB was groomed.

 

Inspection of the media set under Media Sets shows:

Used: 276.1 GB

Free: 14.4 GB

Capacity: 322 GB

 

I would expect the free amount to match or exceed the amount groomed (29.9 GB) but it is less. Also, the capacity minus the used amount is 45.9 GB. Shouldn't that amount match the free amount?

 

Retrospect 12.0.2

Yosemite

Backing up to external firewire disk

 

Thanks in advance for your help.

14.4 + 29.9 = 44.3 GB.

322 - 276.1 = 45.9 GB.

 

Not much difference. Is this a coincidence or is it rounding errors that makes the slight difference?

 

In Finder, perform a "Get Info" on the media set folder. How much is used?

 

Does Retrospect display in GiB or GB?

I think Finder uses GB nowadays.

Hello Lennart:

 

Thanks for your post. The problem was that Retrospect reported less free space in the Media Set (14.4 GB) than should have been free after grooming (45.9 GB, or 44.3 if you prefer).

 

Incidentally, after ejecting the volume and then remounting it, and restarting the Retrospect console, the free space was updated in the Retrospect console to the correct value, 45.9 GB. I think this represents a bug or a limitation of Retrospect. Ideally it would update to show the correct free space in the Media Sets view after a grooming operation. Restarting the Retrospect console was not sufficient to update the value. I also resized the volume from 95% used, to 99% used, and then back to 95% used, before I noticed the free space was correctly reported, so it's possible the resizing triggered the update. I didn't check the free space value before resizing.
