Legato Systems, Inc. was a storage management software company founded in 1988 in Palo Alto, California by four former Sun Microsystems engineers — Jon Kepecs, Bob Lyon, Joe Moran, and Russell Sandberg. Its flagship product, NetWorker, was introduced for Unix in 1990 and became one of the defining enterprise backup, recovery, and archiving platforms of the client-server era, centralizing scheduled backup, media management, and disaster recovery across heterogeneous Unix, Windows, and NetWare environments. Backed by Mayfield, the company went public in July 1995. EMC Corporation announced its acquisition of Legato in July 2003 and completed it in October 2003 for an estimated $1.3 billion, folding the product line into EMC's information-management portfolio. NetWorker survives today as Dell EMC NetWorker following Dell's 2016 acquisition of EMC. No Legato-branded developer or API surface remains: the legato.com domain carries Akamai nameservers but publishes no website, and the company predates modern package registries, so no first-party client libraries exist. This profile is retained as a historical Mayfield portfolio record.
Legato Systems is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Storage, Data Storage, and Backup.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/legato: open an issue to ask a question, or submit a pull request to add artifacts.
