I have one file around 10 gb. It is changing a bit over time. I need to take snapshots of this file and compress them.

Currently I use 7z and each archive is around 700 mb. Are there any other archiver that could leverage the fact that new file is pretty similar to the already packed one and make smaller archive?

You want a backup tool that is capable of doing delta block / block level differential backups. Google says Areca is one such tool.
