(Non-Time Machine) backup software recommendations for Snow Leopard

Question

I have been a long time user of Retrospect Desktop backup software, up to and including version 6.1. It has saved my skin at least twice when I've had catastrophic hard drive failures. I've been using 6.1 successfully in Leopard, under Rosetta. However, as I prepare to upgrade to Snow Leopard, I discovered Retrospect 6.1 will incompatible. According to Roxio:
+Snow Leopard stores some files, including some applications and all files in the /System/ directory, in a compressed format. Retrospect can only restore files in their uncompressed format. This means that a complete OS restore will require an additional 4-5 GB of available storage space on the destination. When /System/ files are restored uncompressed, the Mac OS X may complain about certain files, such as fonts and kernel extensions, not being installed properly.+
Naturally I thought about upgrading to Retrospect 8, which is supposed to be compatible with Snow Leopard, until I read the disaster stories of bug-ridden unfinished Retrospect 8.0 software being released as golden master without a manual. These inexcusable problems persisted through 8.0 and 8.1. Version 8.2 is in beta and addresses restoring from previous version backups and PowerPC compatibility, but it remains to be seen if Roxio will salvage Retrospect and return it to a position of respectability. (Too bad EMC bought Dantz years ago.)
In any case, I'm now looking for other backup software. I need software that does incremental backups, can restore the system to a previous state existing at the time of a given previous (not necessarily most recent) backup, and supports user-defined rules for file inclusion/exclusion, as well as automated scripts. Automatic verification of the backup by comparing original files to the backed-up version (like in Retrospect) is nice, though probably unnecessary most of the time. Time Machine is nice but in my experience doesn't support some of these features and I'm not entirely comfortable relying on Time Machine alone because I've encountered some problems in the past where my backups were lost.
I'm considering Carbon Copy Cloner, but not sure it does true incremental backups and can restore the system to a state that existed at the time of a previous -- rather than most recent -- backup. Also considering Intego's Personal Backup and ProSoft's Data Backup 3.
I would love to hear any recommendations you might offer regarding these or any other backup software solutions.
Thanks.

In any case, I'm now looking for other backup software.

Time Machine can do all that except the scripts - I'm not sure what you're wanting to script - and it doesn't have rules for exclusion, but does let you exclude any items you specify. From the sounds of it, though, you're trying to make your backups more complex than they need to be. Keep it simple and there's less chance for something to go wrong.

You shouldn't be comfortable relying on any single backup program. Backup software is still software, and as such can have bugs and suffer failures. For optimum safety, you should use two different backup programs to maintain a minimum of two separate backups.

CCC does do incremental backups, but restoring to a specific state might not be entirely possible. When a file is added, it is simply added to the clone when CCC runs its next backup. There's no way to know which files were added when, AFAIK. When a file is removed, it is moved from its old location in the clone to an identical path inside a dated folder in the same location as the clone.
Personally, I rely on a combination of TM and CCC. I keep one backup with TM, which lets me go back to any time I want. I also keep several CCC clones of just my user folder (everything else is easy enough to recreate if necessary), with one of them in the safe deposit box at the bank at all times.
