Rsync in Windows: Using the Technology the Smart Way

Rsync backup software is the software, base on the utility. It synchronizes files and directory from one location to another with minimal data transfer. It is name rsync (remote synchronization) for Unix - like and cwrsync for Windows operating systems.

In simple phrase, this utility compute the difference between files of both locations and transfers this difference to the synchronized one. This approach give the great benefit in comparison with traditional incremental and differential relief, when synchronization is implement by rewriting the files of the same name.

There is no need to be a specialist to understand that rsync relief software help to considerably save the transfer time. In addition, it offer encryption and data compression, which serve both the security and the time economy. What in its turn allow, as all we know, to save money.

Features of Rsync Backup Program for Windows

Here we are not going to discuss in detail the subject of using rsync or cwrsync for synchronization of files and folder between several servers and depict its peculiarities for different OS (Unix - Windows or Linux - Windows servers). These are certainly interesting topics, but they may be attractive mostly for server administrators (with whom we will certainly discuss them some other time).

Hence let us pay our attention at implementation of rsync - based synchronization to relief software for Windows, because this subject will be interesting and actual for users of the respective software.

Implementation features of Rsync for Windows

The quality realisation of off - the - shelf rsync (cwrsync) solution in relief software on the one hand will permit to get some advantages of this technology. They are such as: fast incremental relief and restore, reduce in memory usage for relief software, and opportunity to back up not only the Windows servers, but the Unix and Linux ones as well. But on the other hand this will bring its problem too. Here are some of the probable difficulties in using rsync relief software:
  • Limited support of 64 - bit based server platforms;
  • Instability, during continuous work with big volume of Data;
  • Necessity of configure for every task. It can be done automatically, but the problem is, that there are no universal recipes for all servers and all type of data.

So we see the ambiguity of using of off - the - shelf rsync (cwrsync) solution for relief software. But there may be another approach: use not a ready utility, but to adapt its inner algorithm to certain software. In this case an experienced developer could resolve most of the problem, and bring the power of the original utility to the rsync relief software.
