  1. data-bag.org cloud-free file sync & backup Public domain weather images from http://openclipart.org/search/?query=weather by: Machovka, warszawianka, eady, and jgm104

  2. Dangers of the cloud storage ● Cloud storage services abound & free, but ● Can you trust them? – not to harvest & analyze – not to sell or share – not to leak ● your – financial documents – health records – other private files? data-bag.org: cloud-free file sync & backup

  3. Sensitive records: requirements ● Security and control ● Reliable storage ● Simple access procedures ● Safety net against – equipment failures – human errors (including those discovered late) – haste and confusion data-bag.org: cloud-free file sync & backup

  4. Technical goals for data-bag ● Open-source: transparency, flexibility, reuse ● Portable – store and recover files on most machines – no need to install, run from the medium if needed ● Efficient – works with small media: ● flash cards, USB sticks – no need for frequent purges ● Fast data-bag.org: cloud-free file sync & backup

  5. data-bag now ● A Java application – runs from a single ~1.5Mb .jar file – runs anywhere with a Java runtime – supports OpenJDK ● Command-line interface ● Set up once, sync quickly ● Recovery, undo, conflict resolution ● Storage ( bag ) compression & encryption data-bag.org: cloud-free file sync & backup

  6. data-bag in action ● See yourself at www.data-bag.org ● Download the binary by clicking Download ● Install Java SDK & Apache ANT to build from source – sudo apt-get install openjdk-6-jdk ant - or - – http://java.oracle.com/ – http://ant.apache.org/ ● Read doc/manual.md or doc/manual.html for instructions data-bag.org: cloud-free file sync & backup

  7. data-bag is free ● Project's code is covered by – GNU Affero GPL v.3 with amendments ● Code reused from Apache ANT is covered by Apache License v.2.0 ● Libraries are covered by – Commons: Apache License v.2.0 – H2: Eclipse Public License v.1.0 data-bag.org: cloud-free file sync & backup

  8. The future of data-bag ● rsync integration: sync and store on a server ● web-interface: easier to use, server access, mobile-ready ● Android port? ● core improvements: – selectivity – digests vs. dates – renaming/moving files; etc. ● testing and documentation data-bag.org: cloud-free file sync & backup

  9. data-bag and you ● You are welcome to use it ● Your feedback matters ● Skills you can contribute: – algorithms & data mgmt. with Java & SQL (core) – build a web-interface in Java (web) – reading and writing C/C++ with Linux runtime (rsync) – building Android apps with native GUI ● Dual-license contributions: AGPL & Apache data-bag.org: cloud-free file sync & backup

  10. Contacting the data-bag team ● Download at www.data-bag.org ● Join https://github.com/data-bag/code ● Check out www.livitski.name ● E-mail data-bag at livitski dot name ● Ask questions now and later Thank you! Stan. data-bag.org: cloud-free file sync & backup
