TPS Replication PlusTM

TPS Replication Plus is an innovative replication solution that protects data to and from remote locations in real time, with easy backup, fast recovery, and superlative data protection.

Key Benefits

Allows real-time backup to and from remote locations
Supports heterogeneous server and storage environments
Reduces downtime with rapid recovery
Simplifies system management
Provides support for simultaneous backup and recovery at multiple locations

Product Features

TPS Replication Plus is built on innovative Mirror File System technology whose unique file-level operational mechanism replicates files and directories over the network in real time. This invention and its extraordinary scope enable:

Real-time Synchronous Support: In contrast to conventional asynchronous replication setups, TPS Replication Plus supports real-time synchronous replication on the network. Any update on one server is immediately replicated and instantly available on another server.
Multiple Location Support: TPS Replication Plus replicates data at multiple locations over LAN, SAN, and WAN. This greatly improves data protection should a disaster occur.
Data Integrity and Consistency Check: Data integrity and consistency checks are run whenever a server is brought into service, to ensure it contains information identical to its mirroring partner or partners.
Automatic Data Recovery and Synchronization: Data recovery is performed automatically when a server is brought back into service after a shutdown, whether expected or unexpected.
Many-to-Many Mirroring Support: Data can be replicated selectively in real time, based on significance. Mirroring is performed on any directory within a file system, and different directories can be mirrored to different file systems on different servers. Granularity can be adjusted at the directory level.
