There is a server on CentOS 7 with ispmanager, with an SSD disk (on which both the OS and sites) and 2 HDDs (Raid 1).
Physical access to the server is carried out with the help of intermediaries.
Is there a way to remotely and quickly restore a working system with all sites in the event of an SSD failure?

Before you back up a partition, make sure that you will be able to restore it.
Do you have ipmi on the server?
It doesn’t always work out quickly and remotely, I would recommend you in this case: 1. Keep a backup copy on the railway on the server itself, that is, if the hardware is replaced / dev / sda1 and there will be a new ssd, sometimes it’s easier. 2. Look for hosting to reserve with minimal ping to your server.

The simplest and most reliable tool is a full backup. The more convenient. Acronis and others like it.
