I suggest you read the Plan for backup and recovery in SharePoint Server.
You can perform backup in the CA and can not perform restore on the same server. You can refer to the article.
If you have a large server farm or store too much data, it is recommended that you use SQL backup tools. More information, please read this article.
I would suggest you read over the section Overview of backup and recovery in SharePoint Server. This will provide you with the best guidance for out of the box backup and recovery solutions for Sharepoint.
It does not make a difference which server you perform the backup from, but you need to back up to a UNC share. Creating that UNC share on a separate disk ...

Unique permission is still possible, but the option is grayed out on ITEMS tab. It seems to be a known issue only in SP16 (also found in another post).
As a workaround, you can use the “Shared With” option on the display form, which is still available and in function.
As Basic AGs can only protect a single database, it isn't very useful for SharePoint.
While Mirroring has been deprecated for quite a few versions but has yet to be removed.
SQL Enterprise with AlwaysOn Availability Groups would be the modern method of synchronization.
Without more info, there are no special actions you need to take other than shut down all SharePoint + SQL VMs that are part of the farm and move the VMs to the new virtualization host.
If you're changing subnets as part of the move, then you'll need to change the IPs of all of the VMs appropriately and fix up any DNS records as required.
I don't think it is good idea, as it has limitation of the only 1 database in the availability group. Their are limitation in SharePoint powershell commands, where you need multiple databases in the same group i.e Config/ admin. search service.
