[SOLVED] How to disable deduplication in PBS?

[svm482]

I'm looking to disable deduplication in Proxmox Backup Server 2.0-4. I have an HPE StoreOnce that has built in deduplication and want to compare deduplication rates between PBS and the Store once. Is there a way to disable deduplication in PBS?

no. you can use regular vzdump on a directory storage backed by your storage appliance as a baseline.

Thanks @fabian for the quick response. Is there any plans in the future to consider offering an on/off switch for deduplication for specific datastores within PBS?

No plans.

to expand a bit on this: deduplication is at the core of how we store the backups (by chunking data and using the contents as 'address' for the chunk), disabling it would be a lot of work for no gain. it's also what enables us to do incremental backup uploads, which is one of the other main benefits of using PBS..
