Problem backing up when using redis-cache plugin

When using redis-cache, wp-dbmanager is unable to create backups regardless of whether they’re scheduled or on request.

When the plugin is active. wp-dbmanager reports everything is good to go but cannot create the backup with the error “Invalid Backup File Path”.

When the plugin is inactive, wp-dbmanager works without problems.

I don’t know if this happens to all plugins that use redis as a cache, but it could be the case.
