Kid host - disk crash and recovery/cleanup

Yup.  The old boot disk (with Windows Vista & Linux but no /home) crashed.  I did took this as an opportunity to rethink/rebuild my desktop PCs, re-test all old IDE drives lying around, and also redo my backup strategy and include the many laptops that now are lurking around the house without any good backup being made.

So here's what we have now:

Kid2
My main workstation.  Moved the 1TB disk from office that only contained backup partitions, as well as the 160Gb boot disk from office, to have currently 3 SATA disks in it:
sda Two NTFS partitions (1 hidden), swap and Linux boot/root partition
sdb old "home" from Office, with the intention to merge documents into a new /home on kid2 but currently this is full so needs enlarging... after backups are again working
sdc 1TB currently only using the sdc3 as a new /home

Office2
Rebuilt, reinstalled Ubuntu 14.10 afresh.  Empty /home to begin with.  No other users than myself at this point and no documents in there.  To be used as backup server only for the time being.  I might mount /home from kid2 using nfs at some point to avoid spreading personal data on two separate PCs.
