Computers break and servers get hacked. Sooner or later everyone realizes the importance of backing up your important data, usually after a few unfortunate events. I had a few of these, from having my laptop stolen with all the important business data that I didn’t have a copy for much of it (luckily I had my passwords and other sensitive data on a flash drive) and to having servers hacked and losing the sites.
More recently, after researching a but into some different options for backup I got a 1TB external drive and set up some software for backups on it. I also use a few flash drives and some online backup services.
What do you use for backup?
