Roxio Adaptec GoBack (previously known as Wildfile GoBack, Roxio GoBack) is a Microsoft Windows based disk utility, that can record up to 8Gb of disk changes. When the filesystem is idle for a few seconds, it marks these as "safe points". The product allows the disk drive to be reverted to any safe point. It does this by effectively undoing all changes made to the disk since the safe point.

How it works
GoBack replaces the Master Boot Record, and also replaces the partition table with a single partition. This allows a hard drive to be reverted even in the event that the Operating System is unable to boot, while also protecting the filesystem from alteration so that the revert information remains correct.

Incompatible products
Due to the changes made to the partition table, this can cause problems when dual booting other operating systems on the same hard disk. It is possible to retain dual-boot compatibility, but can involve saving the partition table before enabling GoBack, and after enabling GoBack, re-writing the partition table back to the disk (after booting from a different device, such as a Live CD).

It may also be necessary to disable GoBack prior to using certain low level disk utilities, such as formatting software. Such low level utilities which do not first check for the presence of GoBack can (in combination with GoBack) cause data to become corrupted.

Usage precaution
GoBack is not yet officially supported by Windows Vista. GoBack is not compatible with RAID drives. There is a serious "gotcha" with some versions of GoBack. If the system clock date is changed for any reason, this can confuse GoBack on boot-up. It appears to be related to the system restore points saved by GoBack having dates out of order. It then responds with a gb_genlog error. On booting up, it is not possible to get past this point. See http://service1.symantec.com/SUPPORT/goback.nsf/0/2cebac0b31f2c06c88256d21005dd5c5?OpenDocument for more information. Goback 4 will display a notice on bootup if it detects the clock has changed and will update its history log to compensate.
