I see in logs that sometimes ghostjs build a database backup before run migrations.
Its not make senses to me the application make database dump with selects, its very expensive, and ocasionaly, the machine will need a extra memory.
The down, phase of migration is responsible to restore database schema at your previous state, your data is responsibiligy from db, and the management o it, where exists ways much more performatics to do this.
And one question for now,
How can i disable this behavior ?
Many thanks to developers
