I have a multisite and each time I try to create a complete Snapshot or a Managed backup I get errors and they are not created. I was only able to create a only-databases snapshot.
If trying to create a Snapshot for the main site, it fails after reaching the /plugins folder and returns a “Gateway Timeout” error.
If trying to run a Managed Backup, it fails at about 82-87% and returns a “500 – Internal Server Error”.
Max execution time is set to 0, memory limit to 768M, I’m running PHP 7.1.21 and the entire multisite, excluding a wp-content-uploads/snapshot folder, is less than 1GB in size.
