Backup Manager
After purchase of Backup Manager I found that some app apks wouldn't restore. I therefore contacted support. The response was very quick, but following unsuccessful command line attempts to get the restore function to work it was agreed that a full refund would be provided. As promised this was credited to my account in a couple of days. Sean was very helpful and efficient and so, if the software works for others, I have no problem recommending this company. It didn't work for me but I didn't lose out.
