SuperDuper! 2.6.2 now even more so!
Many Mac pros are unnaturally fond of SuperDuper!, the accurately-named backup utility from Shirt Pocket Software. The application is inexpensive (free, actually, if you don't want advanced features -- the best US$27.95 you've ever spent, otherwise), powerful, and easily makes fully-bootable backups of your Mac.
The latest version of SuperDuper! has just been released. Version 2.6.2 is now available and has a ton of new features and fixes. Here's the scoop from the revision history:
Significant copy speed improvements (up to 2 times faster!)
Preserves compression when copying
Fixed extra copying under Snow Leopard
Scheduled copies in old format are now disabled and we prompt the user to recreate
Scheduled copies work on Japanese systems and with more Unicode/composed character drive names
Backup-on-mount should work on 10.4.11
Adjusted SDUtil path to improve robustness when application is moved (now symlinked/refreshed)
Minor copy tweaks
Reworked SL status to use 1000B = 1MB, 1024B = MiB for Leopard and earlier.
Fixed crontab escaping if user has tcsh as their default shell
Fixed issues with explicit Spotlight disable/enable under 10.5+
If you currently have SuperDuper!, you'll be notified of the update the next time you fire it up. If you don't have it, get it.
Thanks to Scott for the tip!
