Are backups deduplicated?

Exclusively within the European Union, on S3 object storage: in France with Leviia, in Germany and the Netherlands on T Cloud Public, or with other European S3 providers (OVHcloud, etc.)

Yes — at the source, block by block.

 

Before anything leaves your server, Cybee splits data into blocks and checks which ones already exist in the repository. Only new or modified blocks are transferred and stored; identical data across snapshots — or across servers sharing a repository — is stored once.

 

The impact is direct: on homogeneous Windows Server fleets, the observed reduction typically reaches 70 to 90%. That means proportionally less storage consumed, lower S3 costs and far less bandwidth used during backup windows.

Deduplication also underpins one of Cybee’s pricing options: when you choose volume-based pricing, you pay for data actually stored after deduplication — not for the raw volume of your servers.
