Environment Planning

Before you deploy Veeam components and start protecting InterSystems IRIS instances, keep in mind the following requirements and limitations:

• The InterSystems IRIS data volumes must reside on a supported storage system that is registered in Veeam Backup & Replication with the Block storage for application protection role. For details, see Registering Storage System for Application Protection.
• If you plan to run the policy in backup mode, at least one Linux-based backup proxy must be available. Veeam Backup & Replication uses Linux-based proxies to mount the storage snapshots and read the data with the unstructured data backup engine. Backup proxies are not used in snapshot-only mode.
• Veeam Backup & Replication interacts with the storage system only over the Universal Storage API and never communicates with the storage system directly.
• Before you restore an InterSystems IRIS instance from a storage snapshot, create an auxiliary host for the LUN mount in the storage system interface. Do not use the VeeamAUX prefix in the name because Veeam Backup & Replication reserves this prefix for hosts that it creates automatically, and removes when the storage system is removed from the Veeam Backup & Replication infrastructure.
• The application backup policy backs up the journal (log) files of the InterSystems IRIS instance together with other instance data but does not process them separately, so you can restore to the state captured in a full or incremental backup, or in a storage snapshot, but point-in-time restore is not available. For details about available backups, see Backup Types.
