I backup my PAF database to my gmail account by sending it to myself as an email attachment, but that quickly becomes "labor-intensive" for backing up photos etc.
I have heard glowing reports by people when they first subcribe to Mozy, and then bitter disappointment when they discover that when they need their backup, the most essential files are missing. Apparently you need to specify both the folders and the file types that are to be backed up, (and the native files of most genealogy software are NOT automatically backed up).
There are many such services. I haven't tried them. Maybe others in this forum would be willing to share their experiences.
You are one of the wonderful people who back up their work carefully. I come across some sad people who wish they had done so.
In late January a frantic phone call was patched through to me: "I had 14,000 names in that file and I was almost ready to publish it. Now it is gone, and I have no backup." (This person had the mistaken idea that their computer couldn't hold any more data and cleaned house. They copied their PAF database to a floppy disk and deleted it from the hard drive, and to put the final nail in the coffin, they emptied the recycle bin! Then they discovered that the floppy disk wouldn't work!)
It is heart-breaking to have to tell someone that thousands of hours of careful research is lost. I never want to have to do it!
Everyone, please, PLEASE make backup copies of your data, and keep them in safe places! Also back up family photos and other irreplaceble items, and make sure they are intact on your new computer before junking the old one.
Another note on backups, if your backups are only to the hard disk, if the hard disk fails you have no data and no backups! A cheap flash drive or a 50 cent CD/DVD can hold an amazing amount of data. They are wonderful investments!
Most of you know this and could do a better job of explaining it than I can. My hope is that I will reach someone who needs the message.
