SQL Server backups are resource intensive operation that strain on I/O and CPU(with backup compression). Always On Availability Group(AOAG) has a mechanism to offload SQL Server Backups and read operations from primary replica to reduce such workloads and utilize secondary replica in a better way. 1. Regular FULL BACKUPS are not allowed from secondary replicas.   But  COPY_ONLY  full backups are allowed on secondary replicas. That means you cannot run regular Full backup  from any of the secondary replica.  Remember that copy-only backups do not impact the log chain or clear the differential bitmap. 2. DIFF BACKUPS(Differential backups) are not supported on secondary replicas . If you need Differential backups for your availability databases don't chose backup preference as SECONDARY ONLY 3. Only regular log backups are supported on secondary replicas. COPY_ONLY log backups are not supported on secondary replicas. 4. Secondary replica must be in SYNCHRONIZED or SYNCHRONIZ
