What is Rsync/Syncrify?
Netcom Rsync/Syncrify is a Windows Server based software application used to synchronize files and directories from one location to another while minimizing data transfer between each location.The data transfer is minimized using an algorithm that will transmit, roughly speaking, only the parts of the backup selection that have changed, right down to a bit level transfer. (This technology is also known as in-file delta incremental transfer.) Along with this minimized data transfer Rsync/Syncrify also compresses all data packets sent, further reducing transfer overheads. To do this bit level data transfer Rsync/Syncrify uses a checksum method. This method creates a short alphanumeric string based on the data it represents. Rsync/Syncrify firstly checks whether any data has changed by looking at file size and modification date. If no data has changed then Rsync/Syncrify will not transfer any unnecessary data, saving you time and bandwidth. If, however, the files do not match, then Rsync/Syncrify uses a checksum method called a ‘rolling checksum’ on the changed files to see where it has been altered or appended. It will then transfer only the altered or appended data within the file. With these two methods Rsync/Syncrify can cater for inserted or added data, removed data as well as shifted data, with a minimum transfer overhead.
In real terms, what this means is more efficient use of your bandwidth and data allowances. As Rsync/Syncrify will only transfer data that has changed and knows when file alterations or movements have occurred, your Internet based backups will take a lot less time when compared other methods.
The key benefits of Rsync/Syncrify:
- Improves offsite backup speed through bandwidth optimization.
- Reduced network data transfer by only transferring new data.
- Open standard secure protocol – Rsync/Syncrify over SSH for maximum security, compatibility and flexibility.
- Rsync/Syncrify via a secure shell (SSH, port 22) means that all traffic over the internet is encrypted.
- Scheduled automatic jobs. Detailed reporting via email.
