Hi,

I'd like some clarification on the definitions in the "Single Instancing" tab on my primary copy please.

I have backed up a single server with a full and some incrementals to get an idea of "SI savings". Total data size is 201GB with a compression ratio of 1:35.

Total size of Single Instanced data: 33.72GB
and
Total data size on media: 114.41GB

I'm interpretting this as I have 201GB of restorable data. Actual space taken up on the maglib is 114GB, of which 33GB is SI'ed". That would mean I'm saving 81GB of maglib space??

I hope I've attached a pic...

Thanks,
 
Are you sure you have that the right way round?

Isn't it;-
Total size of Single Instanced data: 114.41GB
and
Total data size on media: 33.72 GB

This means that there was 114.41GB of data processed & that data was deduped and compressed down to 33.72 GB

Birky,

Nope that was the right way round.
However I've since done a synthetic full (so now have 2 fulls under the belt) and it now looks more like the way you expected it.

Total size of Single Instanced data: 181GB
and
Total data size on media: 115GB
