How can you ensure the transfer of a large volume of data between two remote servers over a 100 Kbps connection?

When transmitting large volumes of data over a connection with a bandwidth of 100 Kbps, it is important to optimize the transmission process and minimize losses. Here are some approaches:

• Data compression: Use compression algorithms (e.g., gzip, zstd) before sending to reduce the amount of data transmitted.
• Chunking: Divide data into small parts to better control transmission and resend only damaged parts.
• Use of error-checking and acknowledgment protocols: For example, rsync or scp with resume options.
• Scheduling transmission during off-peak hours: To make the most of available bandwidth.

Example of using rsync with compression and resume:

rsync -avz --progress --partial source_file user@remote_host:/path/to/destination/

This allows efficient data transfer even with low bandwidth.
