I have a few questions --

1) Yes, catalog backups can be deduplicated, but in some scenarios, sometimes it is best to not leave your only copy of a catalog backup in a deduplication pool/device/server. Some of us prefer to keep the most recent few catalog backups on tape, or basic disk, or advanced disk.
2) A re-activaed policy is not considered as a modified policy, in so far as all clients will not be considered to have changed nor appear to be new. Yes, the usual deduplication will still be ok. But really it depends how long the policy was deactivated for. If the policy was only de-activated for a few minutes or hours, then you shouldn't notice anything. If it was deactivated for several weeks, then previous backups may have since expired from dedupe storage, in which case all backups of all clients in the policy may become effective new full backups.

I would really really really really really really really really really really really really NOT recommend 'deduping' the catalog backup.

Thanks all for the posts/suggestions --
However --
In our environment we tested for the catalog backup deduplication
We had the ddboost plugins on the media server and started the catalog backups on the DataDomain. The Storage type for the diskpool being OST-DataDomain.
We did not find any deduplication taking place also the catalog backup grabbed each and every file in the catalog db.
Not sure why the data was not deduplicated any thoughts on that would be really helpful.... :)

The first copy of the backup won't dedup much, if at all. Try again and you'll should see 'dedup happening'.
However, I still don't recommend it. The catalog is the most important backup you have, and catalog recovery from anything but basic disk, advanced disk or tape can be problamatic.

A full backup was run twice but no effect on the size of the the catalog backups backed up. It takes same time and size for all the copies...
Can it be since its a database it doesn't get deduped...?

Show us screen shots, or text.
