Symantec's Veritas accounted for the most total market share by vendor in this category, but the Extended Edition of Tivoli Storage Manager was the top-selling SKU.
The Extended Edition expands on backup, restore and archive abilities and runs on Windows, HP Unix, z/OS, Linux, Sun Solaris and AIX. It also has NDMP backup for NAS, data de-duplication and Advanced tape library support -- greater than four drives or 48 tape slots, features not found in the regular edition.
As is the case in some other categories, IBM had the best-selling SKU but wasn't the biggest vendor in terms of dollar volume share. IBM sells far fewer SKUs than some competitors. Symantec's Veritas group had the biggest share overall and many more SKUs than IBM, including six of the top 10 best-selling SKUs.
