@Jaymin I meant data loss. I had backed up all my work (which was many GBs) and lost it. back in 2007, the internet was slow and could not take a backup of it on the internet.Movies, serials can always be downloaded, thats not a loss.The real loss is personal data. On average I take 100 pics + 1-2 videos a week.I use 20+ Google accounts to back up those till now.Other than that my code (R&D projects, office work and many other) need back up too. And plus salary slips and hell of other documents (They increase by each passing year!)I dont trust the ext HDD, prefer multiple online backups.
