7. (tie) Dell
Dell's acquisition early last year of EqualLogic gave it an instant pre-built storage channel that included solution providers working with the backup and recovery software related to the EqualLogic iSCSI storage appliances.
In addition, a big part of Dell's overall business comes from its reselling of products from a wide range of vendors, and that includes backup and recovery software.
Dell's product line includes backup and recovery software from companies like Symantec, CA, EMC, CommVault (shown), and Double-Take.
Many solution providers resell the software from Dell because the price they get is often lower than from other sources, especially in small quantities.
