Seeing yet another blog entry about missing or corrupted files, I find myself sticking my nose in. I highly recommend to all authors starting a Dropbox account if you don't have one already. It is free, and stowing a copy of your works-in-progress, story ideas, and unfinished stories is a good idea. I had just uploaded one of the stories I just started, when Microsoft inflicted an update. It failed, but also dorked up my laptop for two days. There was peace of mind in that I knew there were current copies safe and accessible. Mind you, I'm not always good about prompt backups...
Anther benefit is giving your editor(s) access.
On my stories front, I now have two Inkie sequels in progress, a sequel to Siobhan just started, and another Swarm story just a tickle in my imagination. I don't upload until a story is complete and proofed, so it may be a while yet before one sees the dawn...
