Russ, thanks for your response! I'm not real sure what version I have as I'm out of town and only have my iPad. But I CAN tell you that I've only had it for about six to nine months.
I got a message saying it was a mandatory update (about a week ago) and would not let me go forward without downloading the update. When it allowed me to continue, I had this auto backup 'thingy.' it defaults to this, which is my tree name followed by_AutoBackup.
I'm a bit upset with myself for not knowing enough about computers, but also that the update did not come with any explanation. And, frankly, I've had very little luck finding it by doing a Help Search!
So, am I in big trouble for doing my work from this AutoBackup while in Ancestry.com or should I do something prior to syncing with the actual FTM?
