DataDomain Dedup information in mminfo
Hi all,
We have a NetWorker 7.6SP3 environment and are using DDBoost with DataDomain devices.
In the NMC reports, we can see some DataDomain statistics and also see the dedup information for each save set or client or so.
Is it also possible to see this kind of information from the mminfo command?
Ive been reading through the man-page of mminfo, but can't find any field which provides this info.
Kind regards
Tim

size is the pre dup value that standard mminfo see's
size=335633084
this is also reported in the domain dedup statistics wth mminfo -avq ssid=537106346 -S
"v1:1342414086:336723696:297880120:148206473";
the 3rd value from the end
The last value 148206473 is the actual deduped data sent to the DD
standard mminfo withn the attrs switch added will also give you the same output as -S

I do not have Boost, but I believe mminfo -mv was supposed to give de-dupe ratios?

Doesn't seems like it has dedup info
state volume written (%) expires read mounts capacity volid next type

Ah perfect,
The -S did provide some datadomain dedupe statistics.:

Now I just have to figure out what they mean :-D

I'm quite sure there has to be some hidden switch to get that info too. I just did strings against mminfo and could not find obvious hint except -q dedupe one I mentioned earlier.

I know there is dedupe switch (-q dedupe) which used to work with Avamar - not sure if it works with DD Boost though - you may wish to check. If this data is part of mdb, which I don't know, then querying ssid info should show it. In such case mminfo -q ssid= -S should give you detailed data about ssid. If you don't see it there, I suspect this information is not part od mdb and might be calculated with NMC by checking mdb data and data from DD in combination.

Thanks Hoppo,
That's indeed what I need.
The mminfo -r attrs indeed also provides that info. Great!!!
