   In some cases useful info is found in syslog - try

Terminating due to fatal errors.

The instance you're using needs to be able to mount the filesystems being backed up using the "mount" command, the log output here shows that that's failing. Maybe you need to install an NTFS package?

Otherwise, you can pass the --dd option to snap-to-s3 and it'll create a raw image of the entire disk rather than backing up files in a tar (this will result in larger backups if your disk has a lot of empty space / deleted files).
