hi, I have ~1G of personal documents that include all documents that I wrote/edited since high school. Most of them are docx/pptx/txt/markdown/pdf, and mostly text with a small fraction of pictures. I wonder if there is a rock solid backup against almost all possible corrupt in my data files? There are not large files (very few photos/videos) so I do not mind using 10x storage space (with huge redundancy to protect against any corruption) to back up data. Any ideas?
At one gigabyte, your best option is redundancy, not reliability. Put copies on a dozen cheap USB thumb drives and store them with friends, relatives, or just in a metal box out in the woods. Upload to Google Drive, OneDrive, and everywhere else that’s offering a free tier that’s large enough. Burn a fresh copy to a DVD-RW every weekend and stash it somewhere.
When you’ve got enough backups, it doesn’t matter if a few of them fail – you can always grab another copy and restore from that.
