This is a different type of trial offer than the norm as it's for an application you run on your computer, but also use online. It's a very similar setup to Dropbox,...View More except Backblaze helps you easily backup all your files into the cloud. As with all free trials, there is usually always some type of limit imposed. Backblaze's trial limitation of 15 days is particularly interesting because each person's amount of time to achieve a backup is going to be different, which means for some, 15 days may be enough to backup their files, while for others, backing up a fully stocked computer will likely take more than 15 days (as it did with me). By getting users to get their backup started & become engaged with the process, Backblaze increases their chances that the person will want to continue (since they're so close to getting a full backup). This is much different than your typical free trial where you get a taste of what's inside & can back away with little commitment. Backblaze's trial gets you more invested because you're already in the middle of the very same process they're selling you & if you desire to achieve a full backup, you're more likely to purchase. This particularly works for Backblaze because their price levels are very low. They don't need to really convince you of the price. I'd imagine that the combination of the trial commitment & low price converts quite well which is why they make their sign-up process so easy. I ended up biting on the offer myself & backed up my old computer to transfer to my new computer.
