    So, every hour backup. Lets say I ad a lot of videos every hour. After 2 years, I heard Time Machine consolidades the backups so I dont get hourly options for very old backups. how is this consolidation happening?

    Does TM adds everything to a single file, or does it deletes some files in order to preserve just the most importat backup of that day?

    TM will continue to backup all your data on the schedule you have set for it. When the hdd becomes filled, TM works on a "first in first out" basis. In other words it will overwrite the new backup in place of the very first one made.

    It will continue in this fashion, but will ALWAYS backup the same way it did when the drive had more space.

    In short, your oldest backup is replaced by the newest.
