I like SuperDuper! and used without incident it for over a year. However, Synk 6.3.2 works better than SuperDuper! in just about every way. Like SuperDuper!, Synk is one of the only backup utilities that will allow you to make fully bootable backups and still preserve file fork info (or whatever info is normally lost during backup using most other backup applications). However, Synk also does synchronizations and archives, and it allows you to exclude selected files from a backup or sync process.

I like SuperDuper for its simplicity, but Synk Basic is just as simple to use, and Synk Standard is far superior (and it also allows for rules/exclusions). Synk also can schedule backups and archives.

There are three versions of Synk: Synk Basic (which is SUPER SIMPLE TO USE, has a scheduling function, and is very similar to Super Duper which costs $25); Synk Standard ($35), which adds advanced synchronization and more advanced exclusion rules; and Synk Pro (45), which adds N-way synchronization, advanced rule capabilities for arbitrary actions and archiving, more flexible scheduling options, and more.

I am not in any way affiliated with Decimus Software (the makers of Synk). I just want people to know that SuperDuper! is not the only option out there for making bootable backups -- AND for SYNCHRONIZATION. Also, Synk offers a totally reasonable tryout period of (I think) 29 days, whereas SuperDuper only lets you backup 100 MB until you pay the $27.95!!!! In my opinion, those are the worst software trial terms I have ever heard. Furthermore, Synk's developer Ben will bend over backwards to help you.

Again, I swear that I'm in no way associated with Decimus Software or its employees. I'm writing this glowing review because SuperDuper! seems to have some kind of marketing advantage over Synk -- even though Synk is a superior product. So, I'd like to get the word out about Synk.
