Storeonce data backup4/19/2023 ![]() ![]() Considerations on the maximum number of parallel connectionsĮach StoreOnce model has a maximum number of opened files that applies to the whole appliance, so please check HPE documentation and keep this into account when doing multiple activities that may engage more than 128 concurrent operations. ![]() Synthetic Full backups are still recommended for the majority of general cases anyway, as they will reduce the load on the infrastructure and will likely require less time to complete. It’s been observed on multiple, specific environments where the primary storage is fast enough, that Active Fulls perform faster than Synthetic Fulls, regardless of the Catalyst bandwidth modes, with up to double the performance. The Veeam proxies chosen for the backup jobs should also act as Veeam gateways: if the two services run on different servers, the backup data will not go straight to StoreOnce via Catalyst, and the extra hop in network will cause the data stream not to be deduplicated. To get the best level of performance, it’s also best to have multiple proxy/gateway servers in order to distribute the load and avoid saturating the maximum number of connections allowed from a single host. While backup performance for single stream is roughly 30% faster with source side deduplication disabled (“High Bandwidth” mode), it’s still recommended to keep it enabled as it’s possible to achieve a high throughput by concurrently processing more than 10 streams (eg.
