What would happen if a Time Machine backup over Wi-Fi is in progress and I remove my laptop? I just purchased an AirPort Time Capsule and set up backups of my OS X Sierra. (Actually, they're going to a USB drive connected to it but I think it amounts to the same thing.)

If leave for work with my laptop in the middle of a backup, will Time Machine handle that gracefully and do something sane or will it have a meltdown and corrupt the backup and all the other backups and become unusable?
Time Machine should handle this gracefully, with the in-progress backup continuing the next time you connect.

I have many many Time Machine backups that have all been done over wifi, and I have honestly paid no attention to whether or not backups are in progress or complete while taking my laptop in and out of the house.
