So after getting a new laptop, I've turned my old laptop into a small server (installed Linux Mint on it because I still want to control using a GUI (not the best distro for server i know)), and with over 200GB of free storage, I've decided to turn the server into a backup server.
Now, the way I've setup my computer with the server is that:
- My main computer would be connected to the server using an Ethernet cable.
- On the server, I've set the wired connection to
Shared to other computers, which would allow my main computer to have full access to the server (ssh, data, etc.).
And being an Ethernet connection, it should reach around 1 Gbits/sec (which it did when I tested it using iperf):

And when I configured it to use the remote server to store the backup, it seems to work with no problem. Clonezilla was able to detect the server, authenticate and connect to it, so everything looks smooth... until it actually started to back up the data.
At first, the speed was pretty high (7.5 GB / minutes), but when it started dropping dramatically (down to like 600 MB / minutes) and even sometimes to 200 MB / minutes. And I was hoping that maybe it will readjust and bring the speed back up, but nope, it didn't. It kept fluctuating at around 600 MB / minutes.
I don't know if there's a setting in Clonezilla or in the servers that I need to adjust so it would use the highest speed possible, or a bug or an issue which cause the speed to drop when transferring over Ethernet in Clonezilla or ssh.
I'd really like to hear your thoughts and ideas on how I could potentially fix this problem (except ideas like: "Use other back up software").
