Recommend software for cloud synchronization?

Question

Data synchronization

Hello.
Recommend software for Windows 7+ for this action:
- Cloud folder from cloud Mail.ru. Not necessarily a native client. EMNIP, Mile.ru seems to be able to do webDAV.
- Background synchronization of selected folders
- Well, so that it all gets into the cloud folder encrypted.
- Let the encrypted disk or folder be mounted automatically at login
Well, if on the fingers. The file in the My Documents folder has changed, it is synchronized via copying with an encrypted disk/folder, and he/she is already synchronized with the cloud. It's good that there is both a local copy and a copy in the cloud.
Versioning is certainly not a must-have, but desirable. I did not understand something as native under Windows works. If there are interesting and, most importantly, sensible links to read, I will be grateful.
Well, as usual, everything needs freeware. No one will give me money to buy.
P.S. I've been using Linux for a long time. Here it is somehow simpler and clearer with this matter.

Answer 1

www.freefilesync.org - sync. Here you can set the time. It would be possible to use https://ru.wikipedia.org/wiki/Syncthing , there is file system monitoring, but it does not have filters for or I did not find them.
For encryption https://sourceforge.net/projects/encfsmp/ or members.ferrara.linux.it/freddy77/encfs.html On Linux they work well. These are forks and, as everyone says, they are raw. So still looking.
Well, in the cloud of native software.
UPD: All-in-one solution stefanstools.sourceforge.net/CryptSync.html + native cloud client

Answer 2

Everything is very simple. Native client - any cloud, any. And either encfs or, easier, BoxCryptor Classic is used . The latter has a free version with minor limitations.
It is set on a synchronized folder, it is encrypted on the fly, and it is mounted in decrypted form as a virtual disk with which you work. Not to be confused with regular BoxCryptor without "classic". Manual in English here .
This is much more convenient for archivers. In addition, file encryption.

Answer 3

As for me, the most normal information storage system is Google's Dropbox. I use it, I saved information there, and there is the possibility of encryption.
