New data password!
You now have the option to secure your data with a separate password from your account password. Be careful! If you ever forget your data password, your entire backup is useless. There is nothing we can do to help.

Speaking of passwords, how do we handle them?
Explanation for regular folks- We never transmit your password to us or store your passwords in our database. If someone ever "hacked" us, they would not know what your password is. Nobody at Code 42 can figure out what your password is.

Explanation for security nuts- We secure hash (SHA-1) & salt passwords on the desktop. This is your "password" and that is what's encrypted and sent to our data center and stored with your account. We're immune to rainbow table attacks due to mutating password given, unique salt, and repeatedly hashing the sha-1 hash.

New file exclusion option
There are now three ways to keep files from being backed up:
1. Don't select them. Most people get this without reading a manual.
2. Exclude files ending with something. This is pretty easy too. .mp3 if you don't want to do music, and so on.
3. Regular expressions. This requires a bit of technical know how. Buy a [root] beer for your favorite nerd to turn this feature on. The entire path for any file in backup set is sent through regex to allow you to exclude it. We plan on giving a few examples online, for now, here is one that excludes any folder called "Podcasts" regardless of where it is: .*/Podcasts/.*

FileVault on OS X
We supported FileVault on 10.4, but it was a bit tricky to set up. New in this release is support for FileVault on OS X 10.5. You must log in as the FileVault user and install CrashPlan using the new advanced option to "run as user". Due to the way FileVault works, backups can only occur when you're logged in as that user.


And many other changes
Below is a list of bug fixes and minor changes for those who like to know everything. We've organized it by component and feature. No detail is too small for our release list!

CrashPlan Central Changes
• Account password security upgrades - passwords are hashed using SHA-1 and salted at PRO Client before being sent to PRO Server. There is never a time PRO Server knows a user's password
• Master license ID is now included in emails when evaluating our business product

CrashPlan Backup Engine
• Archive - Improved exclusion of CrashPlan archives from backup regardless of location
• Archive - Enhanced the way we store data blocks during backup and restore. This will allow us to more easily add features down the road. Also added some additional information to help in disaster recovery.
• Archive - Better recovery from archives that have been severely damaged
• Archive - Support new private data password option
• Restore - When restoring to another volume, that volume is used as the temporary holding point as data is received to avoid copying the file later. This speeds things up if you're restoring directly to a USB disk.
• Restore - Now avoids applying meta data to containing folder when restoring to locations other than original
• Compression - If for some reason compression fails to truly compress data, throw away results and store data in original state to avoid decompression on restore
• Encryption - When upgrading from basic to PRO version, encryption key is now upgraded automatically from 128bit to 448bit
• Disk - When a new destination is selected, it is now run through a battery of tests before allowing backup data to be stored there
• Synchronization - Better handling of timeouts in high latency environments
• Backup - Identified rare stalling point that was non-fatal but could affect performance, a few computers may notice increased speed while backing up

CrashPlan Desktop
• Login - More descriptive login failure messages to help users who forget their password
• Settings:Advanced- You may now use regular expressions to define excludes
• Settings:Advanced - You can now specify how often to verify incoming backups from other clients
• Settings:Network - You can now disable incoming backup listener on a client in settings/network
• Settings:Network - Public and Private IP addresses have more user friendly display
• Settings:General - No practical limits on retention policies. You can now retain from 1 day to 90 years or if you prefer, forever.
• Friends - Now friends can let friends restore their data "on-site"
• Friends - Fixed situation where friends settings could repaint after a few seconds
• Friends - Fixed situation where inviting a friend from friend screen could sometimes show a blank screen
• Friends:Backup Location - This is now used as a "default". When your friend's new computers back up to you, they'll store data in this location. You can change any computer's backup location later by clicking on the computer name in the "Backup Source" panel
• Backup:Selection - Fixed minor display issue with backup file selection
• Backup:Source - you may now manage various aspects of an incoming backup to a PRO Client by selecting the computer name in the incoming backup portlet
• Backup:Source - Performance enhancements to reduce CPU usage when displaying statistics
• Backup:Destination - Fixed display bug in the detailed destination screen where it could falsely say backup was incomplete when in fact, it was.
• Backup:Destination - shows detailed information about the status of the destination
• Restore - It is now easier to restore to original location
• Restore - Duplicate directories removed when browsing
• Restore - One the job is complete, you can now jump directory to where it was restored using our link
• Restore - Fixed an ambiguous date / time message in restore panel to clear up possible confusion

Windows
• Fixed situation where system tray status would not know name of computer during restore job
• Installer now configures windows firewall correctly for CrashPlan

Linux
• Folder shortcuts in restore panel now work
• Spacing adjusted on new account screen
• Many Installer improvements

Mac OS X
• We now use smarter locations for various supporting folders (i.e. the log folder is now where it should be, not buried in the CrashPlan.app). Requires a new installation to take effect.
• New installer option to run as user logged in. This was required to support FileVault on OS X 10.5

This small release addresses issues discovered in the 2.29.08 release.
All OS versions:

• Fixed possible scenario where already backed up data could be retransmitted again.  This would only happen for really old large files.  This did not put your backup at risk, but it would have used extra bandwidth and disk space at destination.

• Handy dandy shortcuts to finder fixed

• Installer now offers option to upgrade existing installation
  
• Backup archives will be removed in all cases during uninstall if user requests it
  
• Windows upgrade was failing to stop service in rare circumstances, this has been fixed.
  

• No longer in beta
• Installer fixes:
  
• Permissions set correctly for logs on install
  
• Desktop now launches in background
  
• Startup stdout & stderr redirected to log files
  
• Extraction now as current user, not original
  
• Installations can now upgrade themselves

It's a leap day! Time for a new version of CrashPlan! We've also added an RSS feed and blog so you can easily keep track of what's new with CrashPlan.
Upgrade NotesAfter this release it may appear that CrashPlan is backing up everything all over again. Don't panic! CrashPlan is not starting over, it is validating your backup archives with each of your backup destinations to insure your backup archives are in good health.
If you're running CrashPlan PRO the previous snapshot of your backup files is still available. Select "Display deleted files" in the restore panel and expand the older backup set.
CrashPlan Desktop Changes

• Better multi-user support on a single computer- each user gets their own display preferences
• We now use our own file browser to better communicate what you can and cannot do with CrashPlan. This avoids situations where the user can see a folder, but CrashPlan cannot
• Aliases, Shortcuts, Symlinks. These now have a special green arrow through them to help you know they're not the real deal, but a fancy pointer to something else.
• Backup file selection panel behaves a bit more intuitively for those few users who have local disk systems that are quite extraordinary
  
• Fixed restore UI problem when many computers were involved
  
• Option to require login credentials when launching GUI now works as intended
• A problem with specifying default backup location was fixed
• Massive performance improvements in UI, especially on backup tab
  
• Inviting a friend in foreign languages works better via e-mail. Some 16bit characters were getting lost in translation
• We now speak Dutch! Huge thank you to Ceriel. Contact us if you would like to assist in translation to your language
• Our Swedish has improved! Huge round of applause for Jörgen
  
• Those lucky folks with two 30" monitors will better appreciate how CrashPlan behaves when switching back to smaller screens
• Settings have been reorganized somewhat and small text changes throughout to better communicate what's going on
• You can now specify 999 days for deleted file retention for those users that like to keep things a bit longer. Can you imagine what their closets look like?
• Background on a few control settings didn't match the background of the window. In related news, OCD CEO seems content for the moment
• When moving a friend's backup location, the desktop interface is more predictable when switching friends
• It's more obvious what's going on when trying to force a backup during a time when CrashPlan is configured to not run
• Backup destination names now display better if they have odd lengths

• You can now control how much CPU & Disk I/O CrashPlan may use when backing up. To make things even more fun, we allow you to specify them in terms of when you're using your computer, and when you're away! The default is 80% when you're away, 20% when you're there. You could set them to say 100% when you're away. And 0% when you're there. (Thus turning off backup altogether when computer is in use.) Controls are located in the Settings/Advanced screen
  
• Fixed a rare invalidManifestPath issue seen by an unfortunate few folks
• Better cleanup when someone stops using you as a destination
• Lots of new status messages for backup destinations to better communicate what's going on. (i.e. Who is on first.)
  

• You can now force it to try and reconnect to a particular destination instead of waiting for it to try automatically. Handy if you're testing firewalls, etc.
• Buffers adjusted to further enhance throughput on hi-speed LANs.
  

• Volumes are displayed in a more intuitive way in the restore panel (Not everyone knows an external disk drive is located in /Volumes on their Mac! Shocker! In other breaking news, developers think they're just like everyone else.)
  
• Fixed upgrade scripts for OS X 10.4 permissions. If you're upgrading an older release of CrashPlan and you're running OS X 10.4, you may need to manually upgrade. To do this, download the latest version from our website and run "upgrade". Do not run the uninstaller!

• Fixed situation where a removable disk could prompt to insert a disk. Thanks to all who helped track this one down!
• Installer enhanced to better support Vista and add firewall exclusions for CrashPlan automatically
• Restoring files that were "hidden" when backed up, now appear unhidden if being restored to desktop in certain special cases.
  

• We now e-mail detailed invoices each month when you're billed. It includes total usage by computer (Unlike many other online backup providers, we pool your storage together and charge for total used.)
• Our store has been remodeled - new hard drives, new bundles, and a few really neat package deals
• We're now using blogger to announce new releases so you can subscribe to new
