Carbonite does enterprise file backup. OpenText is a big software conglomerate that tends to purchase slow-growing or declining (aka, "boring") enterprise software companies and consolidates them, cutting costs and milking the existing customer base for updates and support contracts. Basically they seem to bet on inertia surrounding technology in big companies, which tend not to change things that are working acceptably.

OpenText also acquired Guidance Software a few years ago. They make EnCase which is one of the largest digital forensic software tools utilized for investigations.

Can't answer fully your question but in 2015 OpenText acquired Actuate a BI and analytics company. It was of interest to me because Actuate at the time was the main contributor to BIRT[0] an Eclipse Foundation project for creating reports. IMHO the best Open Source reporting application. Anyway BIRT has been around for ages and does not seem to have been affected by acquisition. Not much happening there but it was already a mature product.

OpenText is one of the original companies in the Enterprise Content Management space [0].

OpenText also acquired, arguably, their biggest competitor Documentum [1] from EMC in 2017.

Carbonite has been a legit backup service, at times very competitive with its pricing.

Never heard of OpenText. It's a Canadian enterprise information management (EIM) company. Apparently the largest software company in Canada.

carbonite -> backup solutions, similar to Veeam. OpenText -> Enterprise Document Management system (with all the governance stuff big co's want and then some)
