DDB file location for secondary copy on Cloud storage

Hi @AndresL 

Not really sure how this statement in documentation is intended, but for every storage pool combined with it's own DDB I always use separate folders.

It is a separate engine/partition so I would say no thanks to any situation where DDB files will mixed together.

Side note: not sure what the current Q&I times are on your DDB, but by adding another DDB to the same disk please do keep an eye on the performance of the DDB and move a DDB to a dedicated disk if necessary.

@AndresL that does sound a little unclear, I’ve submitted a request to check on the verbiage used

But go with what Jos said, that makes more sense, don’t mix it up in the same folder

I’ll let you know if I find something different

Hello guys,

Want to resume this conversation. I do planning of new media agent setup, and found that newer “Deduplication Building Block Guide” (https://documentation.commvault.com/2023e/expert/deduplication_building_block_guide.html) says:

“You must use one deduplication database (DDB) path only for all the storage pools that are associated with the MediaAgent. The DDB path can be a drive or a folder in a drive on the MediaAgent computer. For example, if you used D:DDB as the DDB path for a storage pool that you created first for the MediaAgent, then you must use the same folder D:DDB as the DDB path for the next storage pools that you create.”

I read this like: Use single folder for all DDBs on media agent. Who knows maybe it works:)

Could you share please your experience, how you organize space for DDBs.

For example you have two huge physical SSD disks in hardware RAID1 array. Do you split this on multiple volumes/partitions, each per single DDB or you create single big volume and use separate folders? Or maybe single folder like mentioned in KB above?

Hello @Jos Meijer ,
You wrote “... for every storage pool combined with it's own DDB I always use separate folders.” 
Do you have in production multiple storage pools with respective multiple DDBs on single NTFS volume? If yes what is your experience, maybe problems? How big media agent is, i mean total single media agent DDBs and Library's size?
