StoreOnce helps with long-term data retention and disaster recovery strategies. It works similarly to Data Domain. It provides site-to-site replication, like StoreOnce to StoreOnce. Additionally, it offers snapshot backup functionality, just like Data Domain. StoreOnce has built-in ransomware protection, with immutable backup options, similar to Data Domain's automated approach. Finally, it integrates with Veeam, just like Data Domain. So, they're very similar products. However, I have not used StoreOnce in a multi-site environment. We do have implementations with single-site, standalone deployments for many customers. But, I don't have any personal experience with using StoreOnce for multi-site replication, like StoreOnce to StoreOnce for disaster recovery purposes. However, I do have experience with Data Domain's multi-site implementation. Its DR and ER functionalities were good, including the bandwidth-compressed layer application aspects.
