I know this isn’t strictly family history, but if you don’t back it up you may lose all your data.
I recently upgraded my hard disk. In the process I discovered that I couldn’t restore the data on to the new disk from my backup. So all my backups were useless. Thankfully I could swap the old disk back in and try another method. Needless to say I have revised my backup procedures and most of yesterday I was using FSync to create a mirror of my data on an external hard disk. I also have monthly disk images on another external hard disk. Hopefully this is better than before.
What do you do for backup? When did you last do it?
