Remote Backup Transmission Time Calculator

This calculator will calculate the time required to transmit a backup over an Internet connection. Enter the original (native) size of the files to be backed up, the compression ratio, and the slowest Internet speed between the Client and the Server.

RBackup typically compresses standard business data about 75%. This means that a file of 100 megabytes will become 25 megabytes before it is sent to the Server. It will be stored on the server in its compressed form. Some data, like Word Perfect and MS Word files may compress as much as 90%, while some files like pictures and music may compress only 5%. Pictures and music files are not considered "typical" business data.

This calculation considers only transmission time, which is directly related to costs of doing business. Time for the Client software to prepare a backup by doing its compression and encryption is not a part of this calculation, and can be effected greatly by constraints outside the control of the software. Transmission speeds can vary widely from this calculation depending on outside factors like the configuration of the software, routers, firewalls, ports, and CPU speeds. This calculation is for optimal connections. This calculator is not intended for use as a benchmark or acceptance test for the software.
