  17. 17. Protocols Send your data to a destination via any of these: <ul><ul><ul><li>SSH/SCP
  18. 18. FTP (it hurt me to type that)
  19. 19. rsync
  20. 20. file:// (local, so thus NFS / other GFS too..)
  21. 21. WebDAV(s)
  22. 22. Even freakin' IMAP(s)
  23. 23. Some I'd never heard of! (Tahoe-LAFS, HSI) </li></ul></ul></ul>
  24. 24. And the Cloud, man... Rackspace CloudFiles Amazon S3 Others?
  25. 25. ENOUGH SLIDES!
  26. 26. Other info Don't use the version in Debian Lenny, it's rather old (0.4): 1) The encrypted chunks are hardcoded to 5MB or so. 2) No support for Rackspace Cloud Files. 3) Missing some neat features Using the version from lenny-backports is fine (0.6): 1) Encrypted chunks are 25MB. --volsize can change this 2) Support for Rackspace Cloud Files (cf+http://), install python-cloudfiles from github 3) Lots of new features, such as --full-if-older-than, --remove-older-than 4) Stores local 'archive dir' cached copy, allows for saving state if backup aborted, among other things
