When setting the backups of many sites in Mainwp, we have to/can set a specific time, but from that indicated time, the backups should be staggered rather than all at the same time (as we see performance drops on some vps’es because of these running all at the same time).
Ideally, it should probably adhere to the Mainwp ‘Maximum simultaneous requests’ setting such as:
Maximum simultaneous requests
or
Maximum simultaneous requests per IP
That way, the backups would automatically be staggered and the pressure on the vps’es would be significantly less.
