Re: The value of "Capacity used" is greater than "Bytes protected"

Jump to solution

Ok, used capacity is the amount of space used by all backup data, it does not contain anything else.

Returning to the previous question: DPN summary report as well as status.dpn %Full value provide that the used space is 13,3TB

I have done the steps described in the article https://support.emc.com/kb/197986 but 7,5TB is still used for the unspecified data. Are there any other method of obtaining a realistic analysis of data?

There is a report named backend capacity report. That can be used to caculate the backup size after de-duplication. You could run it, then get the real size of all backups.

If the size is less than capacity used, that could be some hidden backups somewhere. You can open a case for support.

root@avamar://#: mccli server show-prop

0,23000,CLI command completed successfully.

Attribute                        Value

-------------------------------- ----------------------------

State                            Full Access

Active sessions                  0

Total capacity                   23.3 TB

Capacity used                    20.8 TB

Server utilization               89.2%

Bytes protected                  16.1 TB

The 89.2% server utilisation value is derived from the following calculation

Capacity Used / Total Capacity (20.8TB / 23.3TB)

Please ignore the 'bytes protected' value.  It bears no direct relation to capacity consumption on the Avamar server.

Hi Nicholas,

Yes, I got it. I'm trying to find the solution of how to clean up the "hidden" backups in order to decrease GSAN capacity and make it equal to 13,3TB as it should be, instead of 20,8TB as it is right now.

Hi Tom,

There is no '13TB' of hidden data.  I see a problem with the calculation you mentioned earlier:-

%Full value of 57% is represented the proportion of actual physical space, i.e., used space is 23,3 TB * 57% = 13,3 TB

In actual fact:-

23.3TB == status.dpn value of 65% == 100% of user backup storage capacity

20.3TB == status.dpn value of ~57% == 89% of user backup storage capacity

The values returned by mccli server show-prop are all you need to understand capacity from a backup storage perspective.

These report on the 'green area' that you see in the schematic in https://support.emc.com/kb/457224 below the section titled "How is data stored on the Avamar?"

Thanks,

Nick
