FileReplicationPro release 6.5.3 June 3, 2013  all OSes (except Windows 8 / 2012)


FileReplicationPro release 6.5.3 August 26,  2013  Windows 8 and Server 2012



With this release we complete the upgrade of FRP to natively support 64 bit and 32 operating systems on Windows, Linux and Mac. Additionally we have upgraded all platforms to Java 7 where the bundled Java Virtual Machine is used.


All of these efforts bring FRP to a new level of high performance and stability on a wide range of Operating Systems.



The following are the Changes done for the FRP 6.5.3 Release:


  • FRP on Mac OS joins the rest of our line in using the latest Jnotify library to monitor the file system events.

  • We have integrated a New Filter Component which filters the duplicate modification events that arise in many operating systems, the net effect is to decrease the amount of overhead in preparation for file transfers reducing CPU and memory requirements and adding speed to the processing.

  • We have fixed an issue were in some cases the time stamp on destination folders was incorrectly updated.

  • New logic is now used to update the timestamp of the parent directory for both files and folders to ensure nothing is missed.

  • FRP now is compatible with OSX 10.8.X, at the present time admins must permit the installer to run in the OSX gatekeeper settings. Future releases will not require this setting.


Configuration Changes:


We have reduced the threshold for comparing file changed times to 2 minutes. This means that if a file is updated and it's time stamp is less than 2 minutes different from the other server it will not be replicated until it's age difference exceeds 2 minutes. This is a data safety feature but also impacts the minimum time between events on a file that can be considered as a change worthy of replication.


 February  25, 2013 Version 6.5.2

With this release,  we are completing  a roll-out of FRP which supports 64 bit real time replication for the rest of the major Linux distributions.  This release provides improved performance and better utilization of available memory.  The 64 bit versions are of particular value to our high-volume customers who use modern 64 bit OS's on their servers.

This release also provides performance enhancements and bug fixes to our Windows and Linux 64 bit and 32 bit customers.

We are already at work on our next release which will include compatibility with MAC 10.8.X and Windows 2012 and Windows 8.

New Features

Affected Operating Systems:  Linux
Supported Distributions:  Red Hat,  Ubuntu, Centos,  SUSE and others.
Architecture: 32 bit and 64 bit

Now in addition to our Windows and Mac products, our Linux versions (of the above distributions) feature both 64 bit Java architecture and Real Time Replication.  .

Linux platforms now use the built-in INotify file system extension to capture file system changes and report them to FRP’s replication engine.  FRP then takes immediate replication action as defined by the user.

“Mixed” configurations are supported even for real time so, for example, the user can define real time replication between a 64 bit Windows server, a 32 bit Ubuntu server and a 64 bit RHL server.

Replication Tuning enhancements:

Affected Operating Systems:  Linux and Windows
Linux Supported Distributions:  Red Hat,  Ubuntu, Centos,  SUSE and others.
Windows Versions: XP, Server 2003 - 2008, Vista, and 7
Architecture: 32 bit and 64 bit

“In real time replication, FRP “listens” to file system change events and immediately propagates them to the other server(s).  For example, when a file is added on server A, FRP immediately “senses” the event and copies the file over to server B.  In active systems, a very large number of events may occur in a short amount of time, such as when a large directory with thousands of files and nested sub-directories is added at once to the monitored directory.

This new release includes many enhancements designed to improve the performance and reliability of replication under such conditions.
Bug Fixes

Affected Operating Systems:  Linux and Windows
Linux Supported Distributions:  Red Hat,  Ubuntu, Centos,  SUSE and others.
Windows Versions: XP, Server 2003 - 2008, Vista, and 7
Architecture: 32 bit and 64 bit

Recovery from Real Time job crash - Under certain circumstances, a bug  had the potential of causing data loss on the source machine if a Real Time  job failed mid-way and the Directory Walk was automatically invoked soon thereafter.   We changed the logic to properly account for this circumstance.
Null Pointer Exception - when a missing file pointer was encountered in a disk map.  This problem may occur during real time replication when a very large number of files is affected in a very short period of time (such as when a large set of files and sub-folders is added)  This fix corrects the underlying synchronization issue, the null is handled and replication continues without interruption.
