Remote secure backups

  1. 1. Remote secure backups Paula Valença aka phantas
  2. 2. It is a truth universally acknowledged, that a single geek in possession of an (arguably) good set of data, must be in want of a backup.

  3. 3. I forget when was the last time I actually worked on a PC instead of a laptop I don’t have a home server but I have a remote one ( my birthday is on the 21st of November, I want a 256K slice kplstks) Yes, I have a “portable” hard disk; there’s also a reason I have 3 agendas that all sync
  4. 4. Problem: daily sync critical data to a remote server which is not under my full control. Want: remote server not to have access to plain data at ANY point low bandwidth usage low leakage of information
