vSphere Data Protection generates a significant amount of I/O operations, especially when performing multiple concurrent backups. The storage platform must be able to handle this I/O. If the storage platform does not meet the performance requirements, it might miss backup windows. Backup failures and error messages might occur. Run the vSphere Data Protection performance analysis feature during virtual appliance deployment or after deployment to assess performance.
