the benefit of taking a hot backup is that the database is stille available for use while the backup is occuring and you can recover the database to any pint in time.
the benefit of taking a cold backup is that it is typically easier to administer the backup and recovery process.Since you are taking cold backups the database does not require being in archive log mode and thus there will be a slight preformance gain as the database is not cutting archive log to disk

backup is the duplication of the database at a time when the database is consistent
no transaction should be in progress while is copied
in an incremental backup at a cretain level, only htose blocks that had changed since the last lower-level backup are copied. a full backup has level zero
