Other than the free 50 gigs, this might be the only thing that convinced me to use MEGA. We live in a time where (for many of us), our entire lives are held in the digital atmosphere. And by this I don't mean you're addicted to technology, I mean all of your data is in tech. Your work documents, school stuff, photos, applications, data, and so on. Tomorrow if I didn't have my phone or laptop with me, I'd genuinely be lost because I don't write stuff down on paper anymore (character flaw, let's move on).
This is why backups are so important. I've been a victim (more often than I'd like to admit) of losing data quite a few times. Backups have saved my life (not literally, but close). So here's where MEGASync comes in. Once you download the free MacBook/ Windows/ or Linux app (*note, you do not have to as there is a web version as well, this is just for the sync feature), you're able to configure it so that your entire laptop/computer is constantly backed up to the cloud.
Tomorrow if my laptop goes missing and I had to get another one, I could restore all of my data (which is a lot) with just a few clicks-- this is a game changer for me. What makes it better is that since MEGA is constantly n-sync (haha, music joke), I can open up the app on my phone, or visit the website, or log-in through another country whenever, and access any of my folders where all of my data is saved.
Being able to back up my data constantly, and share between devices at any given time, has increased my productivity rate massively.
