I use backblaze which will backup any modified file and has copies back 30 days, longer if desired. It would be great if there was some way (is there?) To flag if a file was recently encrypted to detect potential ransomware early before backups are corrupted also. Seems like a changed file being backed up could be compared to the previous unencrypted file for this purpose.

Of course this would be more complicated if the files were user-encrypted in the first place, but good tools to detect these things asap would have a good market above & beyond antivirus that is more focused on detection of the virus and not a complete packaged of file recovery as well.
