IBM has released a new data protection product that
keeps a copy of files as changes are made, allowing users to dial
back to recover any version of a document they want on local disks
and on network servers.
The new software, Tivoli Continuous Data Protection for Files,
provides real-time data backup for laptops, PCs and file servers by
continuously protecting information from viruses, file corruption,
accidental deletion or theft of a laptop.
Continuous data protection (CDP), also known as time-addressable
storage, saves all changes at the bit level, time-stamps them and
moves them to local or networked disks to be stored. If a data
restore is required, an end-user or systems administrator can dial
back an application to any notable point in time, such as just
before a virus struck a server.
Microsoft, EMC and Veritas are all expected to announce similar
CDP products soon, which makes you wonder why, if it is such a good
idea, no-one has done it before.
