Dalamser has updated TimePreserver (http://www.dalamser.com/TimePreserver/index.html) for Mac OS X 10.6.6 or higher. It’s available for new users at a price of US$24.99 at the Mac App Store. The new version (1.4) supports customized archving.
TimePreserver lets you make archives of your Time Machine backups stored on a Time Capsule. To use you attach an external disk to your Mac, run TimePreserver, and then store the disk away from your Mac and Time Capsule. Re-attach the disk and run TimePreserver to update the archive. You can use multiple external discs in rotation to provide extra protection. A minimum of two is good, always keeping one in a different location.
According to the folks at Dalamser, the advantages of using TimePreserver are:
° Complete archive of the Time Capsule without it being unusable for hours;
° Integrity of the Time Machine backups is protected;
° TimePreserver understands Time Machine backups unlike generic backup applications.
TimePreserver 1.4 is a free update for registered users of version 1.x. Dalamser also offers TimePreserver Lite 1.4, a feature limited version, in the Mac App Store for free.
