Druva Phoenix is specifically designed keeping in mind the remote office needs. The product incorporates following features to deliver unmatched performance and security while backing up over VPN or WAN -
Unlike most other backup offerings, Phoenix uses backup agent initiated network connections. The backup agent opens and maintains a SSL secure connection to the Phoenix backup server, which the backup server can use for initiating any backup/restore requests. This simplifies configuration and aids in security and scalability of the server. The administrator just needs to open one-way secure port for the Phoenix backup server and can securely backup remote servers over VPN or WAN.

Druva Phoenix uses global source based data deduplication technology to save "only a single copy" of content duplicated across servers. This delivers up to 10 times faster backup with 90% reduction in bandwidth and storage.
Druva Phoenix backup agent automatically detects changes in the network to calculate network latency and available bandwidth. The agent then prioritizes bandwidth based on a percentage limit set by the user and chooses optimal packet size to make the best use of the network availability. This is specifically useful for backups over a weak WAN link. Flexible scheduling runs backups at the most convenient times making backups almost invisible.
Agent-triggered backup architecture and strong 256 bit network and storage encryption makes Druva Phoenix the most secure backup solution available. This comprehensive and multi-layered approach effectively secures data, preventing its compromise or misuse.
