Time Machine and local backups
If you run Time Machine for backups over Wi-Fi like I do, then macOS High Sierra will simultaneous use your remote backup disk and your local disk to save backups to. The reasoning behind this is that in the event the remote backup disk is not available or present, then you can recover files in spite of a missing remote backup disk and recover from the local disk.
In fact, macOS High Sierra manages this disk usage seamlessly without user intervention. It also purges local backups if disk space starts to get too low. However, sometimes the purging doesn't happen to leave enough disk storage for my very large video files and I'll get a 'not enough disk space' message.

Purging local backups
Please note that although this doesn't affect your remote backup from Time Machine, this will get rid of the redundancy (at least until the next Time Machine backup) that a local backup disk will provide. If you need such redundancy or are worried about the recovery of your data then you would be best served to let macOS determine when to purge these files.
