  1. CEO? of Code42, the people behind CrashPlan. Apparently reached out personally when an incident affected 20 users causing data loss. Maybe worth pinging with CrashPlan issues...
  2. Free app to mirror an OSX hard drive onto an external disk, which can, I think, then be booted from. Not possible with time machine, that requires a recopy.
  3. Alternative to CrashPlan. Seems nice, same price (near enough) but will delete external drive files after 30 days. Sucky.
  4. Watch a folder and automatically sync changes to a remote system with rsync / ssh mv. Very neat. Handy for backup syncing.
  5. Tutorial on how to have launchd automatically run scripts (such as rysnc) when USB devices are plugged in, automated backup when a USB drive is plugged in for example.
  6. Tutorial on how to set up OSX to automatically backup when a USB drive is plugged in. Neat.
  7. One strategy to backup encrypted ecryptfs data as suggested by the author of ecryptfs. Useful and simple. Backup the metadata and the raw files with rsync.
  8. A critical utility for ecryptfs called ecryptfs-recover-private which automates and simplifies the process of recovering encrypted home directory data from Ubuntu.
  9. A different strategy to find an encrypted filename from an unencrypted filename under ecryptfs (Ubunut's encrypted home directory system).
  10. Interesting article including a script that figures out a mapping from unencrypted filenames into ecryptfs encrypted filenames. Potentially useful.
  11. Handy howto on encrypting files with openssl and a passphrase. Dead easy, `openssl aes-256-cbc -salt -in file -out file` then `openssl aes-256-cbc -d in file out file`. Can also be used in pipes like `tar cp /blah | openssl aes-256-cbc -salt -out b.tar``
  12. Handy little post. If .svn/tmp dirs are msising, say excluded from backup, one line solution `find -iname ".svn" -exec mkdir {}/tmp \;`
  13. Encrypted backups which don't require you to trust the backup provider, although the code is open source but not free (as in freedom) and so there is only one possible provider...
  14. Article explaining how to mount an encrypted container on a remote system. The remote file container is mounted over sshfs then locally mounted via dm-crypt. This has some major challenges, the approach is interesting albeit not particularly practical.
  15. How to restore encrypted partitions on the ubuntu forums. Could be useful if needing to restore from a backup of an encrypted disk.
  16. Useful article on how to backup and restore MySQL databases. Includes example commands and a basic overview of the theory.
  17. ChironFS is a fuse based filesystem that supports multiple backends. Writes are written to multiple hosts, reads come from a single host. It removes single points of failure and provides real time duplication / backup.
  18. Duplicity performs incremental, encrypted backups onto a range of interfaces including scp, ftp, rsync, WebDAV and Amazon S3. It uses standard tar, rsync and GPG tools, so the data can be recovered manually.
  19. Zettabits is a hardware device you lease and install on your network. It contains local hard drives backed by Amazon S3 storage. You write your data to the box, it writes it to S3.
  20. Bucket Explorer is a user interface (front end) for Amazon S3. It comes in a Windows and a Linux distribution. If you provide "useful" feedback during their beta period, they'll give you a free licence!
  21. Quillen is a backup tool backed by Amazon S3. It's currently (Oct 2007) in Alpha.
  22. JS3tream will read stdin and write the data to Amazon S3. It can be wsed with tar or gzip for online backup. It can also read from S3 back to stdout. Data is stored in sequentially numbered files, so it could be reconstructed with cat.
  23. JungleDisk is a WebDAV server which stores it's data on Amazon S3 (via a local cache). It's commercial, non-free software for Linux, Mac and Widows and costs $20, lifetime registration.
  24. is a backup service based on Amazon S3. You upload your files (via a flash uploader) to and they store them on S3. They charge a small premium over S3 prices.
  25. A comparison of Amazon S3 backup tools, a mixture of Windows, Linux and Mac options.
