I’m not sure how to answer this. Volumes have been written about backup.
Encryption is a security process to hide the contents of a file from prying eyes. Perhaps you are asking about file compression, often used to reduce the size of a file for long-term storage. Most backup programs use some sort of compression/decompression algorithms. Some backup programs can also optionally encrypt the data.
I use the File History program included in Windows 10 for file backups. It’s automatic to a local hard drive and I can find files to restore easily.
My photos are all backed up to my Google Photos account in the cloud. Indeed, all my important files and information are saved in several places online. Business stuff is mostly in Dropbox. Personal stuff is on Google Drive. Microsoft OneDrive is there for redundancy.
I also make an emergency boot USB drive with an image backup for a catastrophic failure.
