IBM has introduced "safety net" software that continually backs up files, protecting them from viruses, file corruption or accidental deletion of data.
Tivoli Continuous Data Protection for Files offers non-stop automatic back-up for files on individual laptops, desktop PCs or file servers, replacing traditional scheduled back-up sessions run by systems administrators.
The software creates a copy of the file on the local machine then sends another copy to a remote server. It allows end-users to restore files that are corrupted or accidentally deleted.
IBM said the software would help people who risk losing hours of work when a file freezes, with even the most recently entered information protected.
The company said its research had revealed that loss of data, including time spent attempting to restore information, was among the biggest problems for mobile workers. Periodic data back-up by systems administrators was often not viable for people working remotely outside the office, it added.
