In addition to the storage space required for backups, the time needed to perform them is also increasing. In the worst case, this can mean that a backup has not yet been completed when a new backup begins, which can lead to various problems. Under certain circumstances, the backup that has not yet been completed could be terminated, and no further complete backups would be performed as a consequence. Alternatively, the backup solution could try to perform the new backup in parallel with the previous one and the backup system could end up failing under the increasing load.
