CobianSoft

By removing this parameter, will the backups be stored in the amount that I set?

Indeed, the lock was there (red flag), is it installed automatically? Accordingly, because of this lock, the old copies were not deleted? Then why do we need a function for storing a certain number of copies?

I don't understand a little what this means

Cobian backup 11 does not delete old backups. The task type is differential, 1 full copies should be stored, 6 difference copies, but when this cycle passes, the old copies are not deleted, there are no errors in the logs
