Dropbox analog with smart sync?

Question

dropbox

Due to the impossibility of paying for dropbox, it became necessary to find an analogue. The killer feature of dropbox in the form of smart synchronization made me return to it many times, now it has become vital at all, since I started working with photos and the source files take up tons of space that simply is not on the laptop. Is there something similar that can be paid with a Russian card?

Answer 1

For example, you can take a mail disk.
Synchronize with it manually, let's say using the rclone program, and connect the cloud itself as a network drive via webdav
Such a killer feature ...)) is solved in 5 minutes by third-party programs)
