Time Machine does not do initial back up and created partial backup file

I would recommend that you start with reviewing the following Apple Support article:

If you can't back up or restore your Mac using Time Machine - Apple Support

We see a number of posts here related to issues with Time Machine backups to the Time Capsule where the backups are either corrupted or incomplete since Apple released macOS Sierra. These same issues do not seem to occur with backup drives that are directly attached to a Mac.

Although there are a few things that you can try to help alleviate these issues, a number of us have been recommending using a third-party solution, like Carbon Copy Cloner, instead of Time Machine for your incremental backup strategy.

Those "few things" to try are:

• Disable any AV apps or software firewalls running on your Mac.
• Verify that your Mac does not have any adware or malware present.
• Configure both your Mac and your Time Capsule for IPv6 Link-local only.
• Assign a fixed local IP address to your Time Capsule.
• Assign a 16-character base station name, that does not include spaces or special characters, to the Time Capsule.

You're very welcome! I'm glad you got it worked out ...
