Natasha from Backblaze here. Just wanted to let you know that we do backup iCloud data, as long as the files are stored locally on your device (not just in iCloud as “optimize storage” / cloud-only files).
If iCloud is set to keep full copies on disk, Backblaze will treat those like normal files and back them up.
More details here: https://www.backblaze.com/computer-backup/docs/en/back-up-ic...
Happy to answer any questions if anything’s unclear.
