CrashPlan For Home Version 4.14.2009

Applies to:


    We've got a cure for the tax man blues: A free CrashPlan upgrade!

    New Private Key Model

    Previously CrashPlan had two security settings that secured the encryption key that protected your backup archive: Account Password (secure) and Private Password (really secure). Now there is a third option for the super-paranoid-can't-be-too-secure types: Private Key (really really secure). The Private Key option replaces the default encryption key with one that you generate yourself.

    NAT-PMP, UPnP Now Supported

    CrashPlan boosts your NAT-PMP or UPnP capable router to work with multiple computers on either side of your firewall or router. This makes it even easier to connect to other computers with CrashPlan no matter where they are.

    Check out your Settings > Network page to see which connectivity mode is currently active. Original CrashPlan TCP NAT Traversal is still in place and used.

    Now with Snow Shoes!

    Don't you hate it when you upgrade your operating system and your favorite apps stop working? So do we. That's why we've been working hard to make sure CrashPlan continues to impress in Snow Leopard. Our engine is 64-bit ready! We'd love to say more, but we're under NDA.


    Check out these changes to backup. And we've added some features to the security and network settings.


    • New custom regex patterns now allow CrashPlan to recognize when Entourage files have changed.
    • New default exclusions ensure that Entourage temp and Windows temp files are automatically excluded.
    • Improvements when backing up to local folders so that syncing happens as expected.
    • The data de-duplication process is even faster.
    • Scanning is even faster!


    • No changes in this release.



    You now have the option to replace the default encryption key with a private key that you generate yourself. You can create your private key in several ways:

    • Enter a passphrase that supplies a private key in the encryption key box
    • Allow CrashPlan to generate a private encryption key for you without entering any text (just click the Generate option)
    • Import an encryption key that has been saved to a text file (e.g. an SSH private key)


    Important Stuff to Know About the Private Key

    • When using private key, you do all the work: You create, manage, and escrow your own encryption key. BEWARE! If you lose your key, it's just like losing your backup. This super, super secure option is only recommended for those folks who never misplace the remote control, always know where their car keys are, and never forget birthdays of their spouse's family. Additional details
    • Important: If you lose the password or key, you will not be able to restore your data.
    • Important: Once you have upgraded your security settings, you can never downgrade.
    • Important: CrashPlan Support has no way to recover your private password or private encryption key because we never have access to this information.
    • Really Important! If you forget your private password or lose the private key that you created, you must reinstall CrashPlan on all computers in your account with a new email address and start backup over.
    • Also: If you must restart your backup, your previous backups are no longer available and cannot be restored.

    Connection discovery is a process that helps determine and test a computer's external connectivity. The process tests various connection mechanisms and also uses a router feature known as port mapping to allow external connections. Using port mapping we communicate with the upstream router and tell it to open a port that maps to our internal address, so that external instances of CrashPlan can connect to a client.

    On the Settings > Network page, you can now click Discover to test, update and view the status of your connection.

    Bug Fixes

    • EULA (in English) now appears in installs for all languages.
    • If you at first mistyped your user ID when logging in to the desktop, but then retype the user ID correctly, CrashPlan now logs you in.
    • Under some rare conditions, changes to encryption security settings were not updating as expected. Settings now take effect immediately and persist in all situations.
    • In some situations, the enable inbound backup option was not being updated as expected. Settings now take effect immediately and persist in all situations.
    • In some situations, if folder parent was missing the file's path was not being identified properly as being selected. Now CrashPlan interprets this relationship and child folders remain associated with parent folders and are selected for backup.
    • Some Windows Services were not stopping cleanly. Now they do.
    • Archives maintenance would sometimes erroneously report corruption detected. These “false positives” have been corrected.
    • Corrected process that under some conditions resulted in a service that would prevent desktop UI from connecting.

    General Enhancements

    Improvements to the UI include making the scan smarter (and faster), clearer messaging and more reliable linking to website from the desktop.

    • Mac OSx: We've made improvements to automatic backup exclusions using metadata tags.
    • Linux: We've eliminated unnecessary waiting for watching process to complete, that delayed CrashPlan start.
    • Changes to wait interval setting that determines when computer is idle (user is “away”) no longer requires a restart and now takes effect immediately.
    • You no longer need to supply a private password to receive backups (one less thing for you to remember.)
    • When you enter a backup code to allow someone to back up to you, you no longer need to enable the inbound backup option.Features
