Veeam One Help me make sense of the Veeam Backup & Replication page

[jcofin13]

I have one large storage server with 4 extents. 110/110/100/100. All of these are in a SOBR.

IF i open VeeamONE and go to the SOBR it has a space usage bar graph showing daily graphs what appears to be the last 2 weeks under the "SPACE USAGE" heading. The blue represents "VM and Computer Backups (TB). Is this supposed to represent some nonsense number before compression and deduplication? How can i have almost 800tb of space when clearly i dont and how am i backing up 400tb of data when im not?

Each day says i have ~800tb of storage with 400tb used. This makes NO sense. Each extents used space in windows shows 20/20/10/10 used respectively if i look at each drive.

On the same page in veeam one, it does show each extent showing Top Extents by Used Space and each of those make sense. The numbers do appear to be 20/20/10/10 as i would expect for each of the 4 extents but the key lists the data as Other (TB). Other what? If it isnt VM and computer backup data then it doesnt exist.

Also if i drill down into the sobr on the left and look at each extent it says there under "Space Usage" that each extent has 220+tb and each daily job for the 2 weeks shows ~138tb of VM and Computer backup (TB). How can this be for each extent when they are not the big to begin with?

Another thing that makes absolutely no sense. If i look at the SOBR item under overview it says i have 156.8tb of full backups and 253.2tb of incremental backups. That should mean im using 253.2+156.8 or 410tb of space. This makes no sense since at the bottom under capacity planning in the same pane it says i have 418tb capacity and my free space is 354.3tb. How can my backups be 410tb in size on a 418tb sobr and still show i have 354tb of free space?

My ultimate goal in looking at any of this is to just figure out how much space i am actually using so i can budget to get new storage. I would think this would take minutes to see but i have been staring at this nonsense for days and cant make sense out of any of the numbers and am extremely frustrated. I must be missing something obvious here.

Hello jcofin13,

We've checked with QA and Used Space on charts should reflect used space on the repository. "Other" could be some non-backup files. So the situation looks a bit suspicious. Could you please open a support case and provide a case ID in this thread so we can check all data?

Thanks

Are you using ReFS by any chance?

[jcofin13]

Yes...we are using REFS at this time.

When using ReFS you get disk space savings because synthetic fulls do not take up the full space on disk.
However if you ask Windows the size of the that synthetic full it will show the full size.

So, for instance your synthetic full VBK file shows in Explorer as 5TB big, but on disk it's actually only taking up a couple of GB's.
If you would ask Explorer the total size of the folder that contains the back-up files it could show up as 200TB, while if you ask explorer the total space used on the disk it would show as 20TB used.

I'm not sure if that is what's causing the views in Veeam One, I haven't used it in a while, it's just a theory.

Dear all,

Unfortunately, the post above is correct, in the case of ReFS it is not a theory.

Thanks
