[cisco-voip] Unity Connection - Mailbox Stores

[Bill Simon]

All,

We have a 10k user base and about 10GB mail store. Backups (DRS) seldom 
worked on CUC 7.1. Just last weekend upgraded to 8.5 and backups are 
working fine for this whole mail store. SFTP backups to a Linux 
server/OpenSSH.

Backups and increased scalability were the reasons we moved to 8.5. If 
you've got a large system, consider moving to this version.
