Problem/Motivation

I set up backup_migrate to backup Default db. Hit the Backup Now button, and got a WSOD. Error log says:

Allowed memory size of 536870912 bytes exhausted (tried to allocate 294912 bytes) in ../backup_migrate/src/Core/Source/MySQLiSource.php on line 456'

On Apache, php8.1, Mariadb.

If it is relevant, I also saw notice "The backup file could not be saved to 'private://backup_migrate/' because your private files system path has not been set. " In fact I had changed the "Private files" destination to be the asbolute path of a cusotm folder oustide my private files directory, so I assumed that the fact that the "Private files" path with machine name "private_files" was not inside a private files directory would not matter.
