About backup storage

Backup storage uses Backup Gateway is a storage access point. It is intended for service providers who use Acronis Cyber Backup and/or Acronis Cyber Backup Cloud and want to store their clients’ backed-up data in the local cluster, in the cloud (like Google Cloud, Microsoft Azure, and AWS S3), or on NAS (via the NFS protocol).

Backup Gateway enables a service provider to easily configure storage for the proprietary deduplication-friendly data format used by Acronis. In addition, the Backup Gateway data can be geo-replicated.

Backup Gateway supports the following storage backends:

• Acronis Cyber Infrastructure storage clusters with erasure coding providing for data redundancy
• NFS shares
• Public clouds, including a number of S3 solutions, as well as Microsoft Azure, OpenStack Swift, and Google Cloud Platform

While your choice should depend on the scenario and requirements, it is recommended to keep Acronis backup data in the Acronis Cyber Infrastructure local storage cluster. In this case, you can have the best performance due to WAN optimizations and data locality. Keeping backups in an NFS share or a public cloud implies the unavoidable data transfer and other overhead, which reduces overall performance. Besides, with external storage backends, redundancy has to be provided by the external storage. Backup Gateway does not provide data redundancy or perform data deduplication itself.

Backup storage architecture

Backup Gateway, the backup storage access point, runs as a service on the Acronis Cyber Infrastructure nodes. It is recommended to deploy it on two or more nodes for high availability.
