why is time capsule not doing a full system backup?
It's only backing my users folder and nothing more. Their is nothing excluded from time machine in the options. Also I have my time capsule set up the right way.
TM only does one full system backup when it first starts.. all other backups are incremental and so will generally only involve the user folders.
To force it to backup everything, delete the old backup or use a different target disk and it will start over with a new full backup.
