Features

Leverages the same replication technology as CVS MultiSite.

► Delivers transaction-aware continuous hot backup of the primary server to one or more backup servers over a LAN or WAN.

► Meets a recovery point objective (RPO) of zero.

• Everything up to the moment of failure is captured and recovered automatically without administrator intervention.

► Meets a recovery time objective (RTO) of zero.

• Users fail over to backup servers automatically and transparently without anyinterruption in service.

► Ensures zero loss of data and no lost development time.

• Eliminates the risk of human error during disaster recovery.

► Significantly more cost effective than disk mirroring solutions that won’t work over a WAN.

Architecture

► Replicators used by WANdisco’s CVS MultiSite are used to:

• Ensure continuous hot backup of the primary server to one or more backup servers.

• Provide self-healing capabilities to automate the recovery process when the primary server comes back online.

► The failover agent automatically redirects clients to backup server(s) in the event of network or server failures.

Network Optimization

Reduces network traffic and bandwidth costs

► All reads are local and generate no WAN traffic.

► Streaming on Persistent connection.

• TCP 3-Way Handshake Eliminated

• Eliminates normal CVS chattiness over the WAN

► Eliminates tag explosion problem.

• Only the tag command and the associated metadata is sent.

• Other solutions send all of the tagged files as well.

► Server Versions Supported

• CVS Server versions 1.11.17 to 1.11.21 are supported

► Supported Clients

• CVS command line, WinCVS, TortoiseCVS, SmartCVS, Eclipse and IntelliJ.

► System Requirements

• CVS MultiSite will run in any J2SE 1.5 or above compliant Java runtime environment. A minimum of 64 MB of RAM and 450MHz CPU is recommended for the server

System Requirements

► Meets a recovery point objective (RPO) of zero. Everything up to the moment of failure is captured and recovered.

► Meets a recovery time objective (RTO) of zero. User access is restored immediately after a server failure or network outage.

► Requires no retraining. Developers and administrators use the Subversion clients and tools they’re familiar with.

► Backup servers can be on the same local area network (LAN) as the primary server, or located remotely over a wide area network (WAN).

► Minimizes network traffic and bandwidth usage over a WAN.

► Can be implemented standalone, or in conjunction with WANdisco’s CVS MultiSite solution.
