Those who do backups and those who will...
Seriously, I can't imaging doing something like research or writing PhD thesis and not having at least one off-site backup.
Just get yourself couple of pendrives and rotate them somewhere else than where you live and work.
I personally have more data. For my backup needs I use 3 4TB drives, a USB HDD docking station and a script to detect when one of the drives is inserted and make backup of data from all places in my home that I need backed up.
I have one drive inserted in the station (once inserted, it will attempt one backup per day). One standing by or in transit and one with the family.
At any point in time at least one of those drives is safe with my family which I visit regularly. When I drive there I yank the backup drive from the station, immediately replace it with the standby drive and take the fresh backup with me. When I am going back home, I take the one drive that was previously kept by my family to use it as a standby.
It is not complicated, you can do the same with a pendrive.
There is no paid software involved, I wrote the script over the years but it is simple and has no extra features. It only detects when the drive is inserted (each has a file with info), makes full/incremental backups (full backup automatically after inserted, incremental every night) and removes old backups and linked increments as needed. Restore is manual as files are just tar.
