Data

Hi. I wondered how everyone stores and backups both their projects and specifically data used in projects (samples, sounds, software etc).
Ive made a massive error all mine were on two external hard drives which were not backed up and have now failed. Im in the middle of a panic and trying to get data restored.
I don’t want to make same mistake again hence asking what others do.
I have quite alot of files and seem to need somethung more reliable or less prone to failure than USB external hard drives. Any advice welcome
