I just got back from 3 week vacation and… it is a second time I lost all vacation photos.
First time I lost vacation photos was due to hard drive failure in my laptop close to the end of the vacation. The problem was mechanical, thus recovering disk content was just too expensive ($2000). I had an external drive with me to make backups but never got around to actually do them. From that case I told myself I’m going to do backups every night on my trips.
A few years forward. This time I have done backups to two external hard drives. Both laptop and hard drives as well as some other valuables were in one very important bag – the most important bag, the only bag not to lose. And I lost it in an airport. Later I was contacted by airport authorities that the bag was found and everything but laptop was in it. I have not got the bag back yet and I can only hope that I eventually get it back with hard drives undamaged. But I was not very persistent about backing up to external hard drives every night and thus a lot of photos are lost for sure.
What I have learnt from this? First, backup should be simple and done consistently during a trip. Second, those backups should be placed to different bags to decrease probability of losing all photos as a result of loosing one bag.
