Schmitz Code42 Software has released [1]CrashPlan 4.3 with added support for installing the Internet backup software on a per-user basis, which is ideal for backing up data for multiple individual users who are logging into the same computer (such as in multi-user desktop environments). Each installation behaves as a separate device with its own settings, license, and backup archive, and it is recommended for advanced users only (see this [2]support document for more details). CrashPlan 4.3 now uses dynamic port selection when connecting to the Code42 cloud and computer destinations, fixes a bug that prevented restoration of a file that contained an apostrophe in the filename, and corrects an issue that prevented the critical backup alert email (sent after 7 days by default) from being sent in some instances. There is a [3]known issue that requires those running Mac OS X 10.6 Snow Leopard to first update to version 4.2 from a previous version before updating to the latest version 4.3.
