Abstract: Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides many-to-one data mirroring, including mirroring from local servers running the same or different operating systems and/or file systems at two or more geographically dispersed locations. The invention also provides one-to-many data mirroring, mirroring with or without a dedicated private telecommunications link, and mirroring with or without a dedicated server or another server at the destination(s) to assist the remote mirroring unit(s). In addition, the invention provides flexibility by permitting the use of various combinations of one or more external storage units and/or RAID units to hold mirrored data. Spoofing, SCSI and other bus emulations, and further tools and techniques are used in various embodiments of the invention.

Systems and methods for performing data replication
Anand Prahlad,David Ngo +1 more
- 18 Dec 2006
TL;DR: In this paper, the replicated data represents a known good state of the application, as determined by the consistency point entries, and the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replica data and to logically associate the copied data with a time information indicative of the source system time when the application was in the known good states.

- 21 Oct 1996
TL;DR: In this paper, the authors propose a system for backuping files from disk volumes on multiple nodes of a computer network to a common random-access backup storage means, where duplicate files (or portions of files) may be identified across nodes, so that only a single copy of the contents of the duplicate files or portions thereof is stored in the backup storage mean.
