Back-up software manufacturer Dantz may be sold to EMC Corporation.

Dantz, which publishes Retrospect, is particularly strong in the small to medium-sized storage market. The acquisition is thought to be an attempt by EMC to raise its profile in that market.

EMC vice president Victoria Grey told "We are in discussions with Dantz about an acquisition. Dantz has complementary technology to our product set and additional channel strength in the SMB market."

The deal has not yet been confirmed.
