How to set up backup recovery in isp?

Question

ISPmanager

I reinstalled the server + isp manager lite 5.
Backup is set up via Yandex, and I see copies:

But when I go to any particular date, it's empty:

How to be, why so?

Answer 1

I’ll answer myself - I don’t know why it was like this:
Centos was standing - backups were made on it
Then I installed Debian - it was not possible to restore copies
ten times reinstalled both the OS and Isp5 - to no avail
And then I thought, I’ll return Centos back. And about! Miracle - backups are restored!
How is that?!
