Disable Software Compression on a second copy

 hello @JanR 

You can do this by going to storage resources → Right-click the AUX copy and then click Properties → Click the Settings tab and unchecking the "Enable Software Compression with Deduplication" checkbox.

Hi Mohamed,

thx for the reply!

To understand it better…is then the compression on the primary copy disabled too, or on the secondary only?

I am asking, since I want to disable the compression (and deduplication) on the secondary copy only.

The primary copy should be deduplicated and compressed.

hello @JanR 

This setting applies only to the secondary copy in the storage policy. The primary copy will remain enabled unless you change it.

@Mohamed Ramadan 

Thx Mohamed, but I am a little bit confused, sorry.

My second copy is a non deduplicated one, so I can‘t activate the seeting shown in the first screenshot since there isn‘t a dedup engine.

Or did you mean, I have to deactivate it in ddb engine for the primary copy and then I am able to set it for each storage policy copy itself?

hello @JanR 

 No, don't disable deduplication for the primary copy (as you mentioned, it should be deduplicated and compressed). You only need to uncheck this option for the non-deduplication storage policy copy (your secondary copy).

@JanR You can create a second copy as non-dedup copy only (using a non-dedup pool). On the copy you can choose to disable compression as guided above.

Hi @Abhishek Narulkar + @Mohamed Ramadan!

First of all, thx for your help.

If I have a look on my secondary copy (which is a non deduplicated storage pool, the option to disable the compression is not visible, please check the screenshot below.

Have I done a mistake before?

hello @JanR 

Hmm, something seems to be missing... the software compression should be there.

can you check i know this for dedup SP expand Storage Resources > Deduplication Engines > storage_policy_copy. Right-click on the deduplication_database and select Properties. The Deduplication Database Properties dialog will open. Click the Settings tab and check the box for Enable Software Compression with Deduplication.

“The software compression settings are applicable only to the primary storage policy copy and not applicable to the secondary copies.

The auxiliary copy operations follow the compression settings of the primary copy”

Hi @Erase4ndReuseMedia,

do you have this information from the documentation?

If so, do you have a link?

Apologies, the link should have been included in my last comment: 

Software Compression (commvault.com)

​@JanR What was your final resolution to this? Did you have to either disable compression on the primary (which would create a new baseline of data and inflate the DDB) / create a new Storage Policy with compression disabled and setup the copy using DDBoost that way?

Experiencing the same issue right now and curious how everything worked out for you.

Thanks in advance.
