Worldwide purpose-built backup appliance (PBBA) factory revenues declined -1% year over year totalling $781,6-million in the second quarter of 2015 (2Q15), according to the International Data Corporation (IDC) Worldwide Quarterly Purpose-Built Backup Appliance Tracker.

Total PBBA open systems factory revenue decreased -1,9% year over year in 2Q15 with revenues totalling $705,6-million while the mainframe market experienced growth of 7,9% for the same period. Total worldwide PBBA capacity shipped for 2Q15 was just shy of 664 petabytes, an increase of 12,9% year over year.

“The worldwide PBBA market experienced a year-over-year decline in the second quarter of 2015 as the market continues to evolve,” says Liz Conner, research manager: storage systems at IDC. “Focus continues to shift away from hardware-centric, on-premise PBBA systems to hybrid/gateway systems. The results are greater emphasis on backup and deduplication software, the ability to tier or push data to the cloud, and the increasing commoditization of hardware, all of which require market participants to adjust product portfolios accordingly.”

EMC maintained its lead in the overall PBBA market with 60,1% revenue share in the second quarter, followed by Symantec with 13,4% share. IBM was in the third position and HP was in fourth, posting 6,9% and 4,7% market share, respectively. Barracuda finished the quarter in the number five position with 3,4% market share.
