Not optimal behavior for low quality network connections

[mio-19]

After experiencing numerous failures due to unstable network connections, I discovered that btrbk is set to send a relatively large incremental backup instead of smaller incremental backups, making it challenging to complete the backup process under unstable network conditions.
Here is what btrbk currently do
(I used a port forward program because one machine doesn't have public ip address)

btrbk run -n

For a better experience on low quality network, a strategy is to send 20240312 snapshots first
