Primary Disadvantages of Backup Exec 2012:
Backup Exec licensing fees tend to be expensive for growing businesses due to the licensing model, which includes charging on a per-feature, per-client, per-operating system, and the like basis.
Backup Exec tends to have a lower ROI (Return on Investment) and higher TCO (Total Cost of Ownership) due to the higher operational expenses of putting together, managing, and monitoring servers, storage, networks, operating systems, and data protection (backup, archiving, disaster recovery) software.
The non-integrated nature of Backup Exec leads to finger-pointing among the server, storage, networks, operating systems, and data protection (backup, archiving, disaster recovery) software vendors when a problem occurs.
Limited heterogeneous support to Windows, Linux and Mac
Customers dissatisfied with new release and less functionality
No desktop/laptop support – developed as a non-integrated product offering
