Hi,
I currently use a program called copywhiz on windows that backs up any files or directories created after a certain date to a usb hard drive and runs once a day.
I want to transition fully to Linux. Is there any easy to use software that works on Linux that can do this?
P.S. I have tried creating a bash script to do this but for some reason it has trouble with the date part. So a software solution would be prefered.
I think that for your use case (backing up to an external USB drive) great option would be something based on Borg.
Vorta and Pika Backup are great graphical tools for Borg program, with the first being more advanced while the latter being simplier.
