Version 4.3.0 of the CrashPlan app is a minor release that includes a number of enhancements and fixes. All CrashPlan apps that connect to the Code42 cloud will be upgraded over several days, beginning on June 30, 2015.

Per-user installation on Windows and OS X

The CrashPlan app can now be installed separately for each user account on Windows and OS X computers. When you install the CrashPlan app per user, each installation behaves as a separate device with its own settings, license, and backup archive.

This is only recommended for advanced users. Before installing the CrashPlan app per user, review these important considerations.

Fixes and enhancements

  • Security updates.
  • Performance and stability improvements.
  • The CrashPlan app now uses dynamic port selection when connecting to the Code42 cloud and computer destinations. If necessary, you can review our tutorial to identify the ports used by the CrashPlan app.
  • Corrects an issue that prevented users from restoring a previous version of a file from the CrashPlan web app when the filename contained an apostrophe.
  • Corrects an issue that prevented users from using the CrashPlan web app on OS X and Linux to restore files in a folder with restricted permissions.
  • Adds a filename exclusion for Windows devices to not back up files or folders ending with .tmp.
  • Corrects an issue introduced in 4.1.6 in which the critical backup alert email for a computer not backing up (sent after 7 days by default) would not always send. The warning backup alert email for a computer not backing up (sent after 3 days by default) was not impacted.

Known issues

Maintenance update 4.3.3

Version 4.3.3 contains minor fixes for a small number of enterprise customers, and was also released to some CrashPlan for Home customers. No CrashPlan for Home fixes or enhancements are included in version 4.3.3.

Some devices were upgraded automatically to version 4.3.3, and some will remain on version 4.3.0. Version 4.3.3 behaves exactly the same as version 4.3.0 for CrashPlan for Home customers.
