Final answer:
To manage a 250 GB backup hard drive that's filling up quickly, consider options like buying a larger drive, deleting old backups, compressing files, or adjusting Time Machine settings.
Step-by-step explanation:
If you find that your 250 GB backup hard drive is filling up faster than expected, you have a couple of options for managing your storage space. One option (A) is to increase the backup disk size by purchasing a larger hard drive. Alternatively (B), you could manually delete old backups that are no longer needed to free up space. Another viable solution (C) is to compress backup files, which can save space, though this may impact the speed at which you can restore from those backups. Lastly, if you are using a Mac with Time Machine, you can (D) adjust Time Machine preferences to manage the frequency and size of backups, which can help to prevent your drive from filling as quickly in the future.
