The document outlines a comprehensive backup as a service (BaaS) architecture that emphasizes high availability, multi-tenant support, and efficient backup management. Key features include offline data recovery options, client state monitoring, and data encryption, as well as optimization for WAN bandwidth and deduplication. The solution aims to provide a fully software-based backup management experience without the need for dedicated hardware.

 Backup as a Service (BaaS/SaaS) architecture
 (Web) GUI designed to manage an enterprise service
 Service cluster (load balancing + high availability)
 Multi-tenant / Multi-client (Roles/Permissions)
 Client repositories consolidation but segmentation (security)
 Offline data center site restore to LAN Shared Folder, FTP, SSH, CD/DVD
Burn, USB disk/stick (When client s link is down or any other cases)
 Full Backup Cycle Management (Backup programing, Restore, Validation,
Verification, Recycle, Reporting)
 Client state (error) monitoring
 Quota management (email warning configuration)
 WAN bandwidth/transmission optimization
 Repository encryption (Ciphers key per client)
 Virtualized backup servers (is a plus)
 Repository deduplication/compression (is a plus)
 SNMP backup server healthness monitoring (is a plus)
 Licensing scheme based on disk repository size or client numbers.
 Over licensing support is needed: due to average time to buy more
licenses while accepting new clients
 Unstructured data (compacted database dumps, compressed files, source files, office files)
backup (0.5 – 1 TB daily per client) depending on link type and bandwidth
 VMWare/vCenter/Hyper-V/System-Center snaphost generation and backup
 GUI designed to assist and help client s backup operators
 Neither client side backup appliance nor dedicated backup server (All-in-one 100% software
solution is the expectation)
 Active backup agents for unstructured data (Windows/Linux Operating Systems)
 Full Backup Cycle Management (Backup Programming, Restore, Validation, Recycle, Reporting)
following roles/permissions assigned by the provider
 Backup download and client side GRANULAR restoration
 Quota revision (email warning configuration)
 Encryption before data transmission
 Deduplication/Compression before data transmission (on site processing).
 WAN bandwidth optimization and intermittency tolerance (Last byte restart)
 Content filter by file type (is a plus)
 Virus scanning (is a plus)
 Complete and simple recovery procedure from backup client/agent crash
