After a long wait, Shirt Pocket has released SuperDuper 2.7.2 with full support for OS X 10.9 Mavericks, including a workaround for a problem in Mavericks with Spotlight handling, plus the return of auto-mount and auto-eject for scheduled copies. (For some technical background on the delay, see this Shirt Pocket blog post.) The drive-cloning and backup app also makes volume size information available in the source and destination pop-ups, improves Smart Update speed, transitions scheduling from cron to launchd, and does away with annoying and incorrect
security prompts associated with scheduled copies. SuperDuper 2.7.2 now requires 10.6 Snow Leopard or later, but version 2.7.1 is still available for those running 10.4 Tiger and 10.5 Leopard. (Free for basic functionality, $27.95 for additional features, free update, 2.9 MB, release notes)
I can't recommend SuperDuper more highly.
It saved my neck about five years ago when my hard drive died. It became flaky before dying, which gave me a couple of minutes to save the InDesign document i was working on to a flash drive. With that and the evening-before backup with SD, all I needed to do was restart off my external drive and within 10 minutes I was back at work with nothing lost.
Too bad all of life's troubles aren't that easy to fix.
Too little too late. SuperDuper has always been my go-to backup software. Mavericks was released four months ago, and SuperDuper has been a pain ever since. Here's hoping the update fixes the problems.
I've found that Carbon Copy Cloner works well under Mavericks with no failures so far.
Transition from Cron to launchd is not quite correct, the Backup-Time is still written into the user's crontab, then launchd is used to run an Applescript *every minute* to parse the crontab entry and start the backup if time/clock match.
