Alternative for Yandex.Disk?

Question

Data synchronization

Good afternoon,
There are several win7 machines directly connected to the internet.
You need a repository that machines have access to and upload files to.
Load:
- Small files will be constantly uploaded there. Approximately 1 file per second, 10-20 kilobytes.
What is now:
- Yandex.Disk. But with such a frequency of recording, it is very slow and poorly synchronized.
What I tried:
- Webdav. There were problems with caching (files stopped being deleted - replacing old versions, and this is critical).
Requirements:
- One way or another, there must be integration with windows explorer (network drive, ftp server or something else).
- Encryption
There is an idea to add all machines on win7 to one VPN and make ftp visible only through the VPN, but maybe there is a simpler solution?

Answer 1

Replace the word "file" with the word "information" - and, perhaps, it turns out that you do not need either storage, or explorer, or Windows. A browser and a web service are enough.
The question is where those files come from and how they work with them.

Answer 2

ftp is the easiest.
nextcloud is the most prudent.
giving up windows is the best thing.

Answer 3

if Windows is fundamentally the main platform, the answer suggests itself onedrive

Answer 4

Syncthing, BitTorrent Sync

Answer 5

I vote for nextcloud.
It picks up changes in files on the fly and immediately synchronizes to the nextcloud server. The latter can be located on the same subnet for fast synchronization.
By itself, the Yandex.Disk program client should probably also be good, but synchronization cannot be faster over the Internet than on a local network.

Answer 6

SeaFile, DropBox, GoogleDisk, OwnCloud, etc...

Answer 7

There is a cool program for synchronizing free file sync + ftp
Et as an option.
If it's smart, then of course a personal cloud with an ssd drive.
