Rsync for Your Network Backup Strategy
Rsync backup software is the software, based on the tool. It synchronizes files and folder from one location to another with little data movement. It is name rsync (remote synchronization) for Unix-like and cwrsync for Windows operating systems.
In simple phrase, this tool compute the inequality between files of both locations and transfers this inequality to the synchronized one. This method of approaching bring the great point in comparison with original incremental and differential backup, when synchronization is implemented by revising the files of the same name.
There is no need to be a expert to understand that rsync substitute software let to very well save the movement time. In addition, it offers encryption and data compression, which serve both the safety and the time economy. What in its turn allow, as all we know, to economize money.
Functionality of Rsync Backup Solution for Windows
Here we are not going to discuss in detail the subject of using rsync or cwrsync for synchronization of files and directory between several servers and depict its peculiarities for different OS (Unix-Windows or Linux-Windows servers). These are certainly entertaining topics, but they can be attractive mostly for server administrators (with whom we will certainly discuss them some other time).
So let us pay our attention at realization of rsync-based synchronization to substitute software for Windows, because this subject will be entertaining and vital for users of the relevant software.
Performance Functionality of Rsync for Windows
The quality implementation of off-the-shelf rsync (cwrsync) utility in substitute software on the one hand will permit to get some advantages of this technology. They are such as: fast differential substitute and recovery, minimal in memory usage for substitute software, and capability to back up not only the Windows servers, but the Unix and Linux ones as well. But on the other hand this will grant its problems too. Here are some of the probable difficulties in using rsync substitute software:
- Bounded support of 64-bit based server platforms;
- Unstability, during continuous operation with big volumes of Data;
- Necessity of configure for every task. It can be done automatically, but the problem is, that there are no universal solution for all servers and all kind of data.
So we notice the ambiguity of using of off-the-shelf rsync (cwrsync) solution for substitute software. But there can be another method of approaching: use not a ready tool, but to adapt its inner algorithm to certain software. In this case an experienced programmer could resolve of most of the problems, and grant the power of the original tool to the rsync substitute software.
