Ok, I think I have all the pieces in place for me to break free of Google
1> Odroid +64GB USB (DietPi) for backing up my phone (next cloud + syncthing?)
2> CubieTruck (Armbian) with 60Gigs hdd space for using imap-backup
3> D-Link DNS-323 running Alt-F with 3TB of storage for files / backups.
4> a Spideroak a/c I've had for ages that has 25gigs
Now to get it working!
