CrashPlan 4.3

Code42 Software has released 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 users who log in to 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 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 known issue that requires those running Mac OS X 10.6 Snow Leopard to update to version 4.2 from a previous version before updating to the latest version 4.3. (Free with a 30-day trial of CrashPlan’s online backup service, 55.9 MB, release notes, 10.6+)
