The program is fine, but has a major flaw. After you are done backing up it produces a log. Non critical errors are listed in a section. But critical errors are not listed in a separate section but noted in the regular log.
Since back up may be thousands of files you have to go through pages and pages of the log to see what did not transfer.
It also lists puzzling errors like file name may be too long. Fair enough but if this is so, how come I can click and drag it to the same place OR copy and paste file with no issues?
Also it should guide you through small issues. Like (slanted apostrophe)won't transfer but the ' will.
The software developer responded to this review on Dec 10, 2012:
We ve recently released V6 which resolves your issues: errors are listed in their own section, there are no filename length limits, and many other new features. Enjoy!
