One question, why use rclone for the Backblaze B2 part? I use restic as well, configured with autorestic. One command backs up to the local SSD, local NAS, and B2.
I explain in the post. Here's a copypasta of the relevant paragraph:
"My reasoning for splitting these two processes — restic backup and rclone sync — is that I run the local restic backup procedure more frequently than my offsite rclone sync cloud upload. So I’m OK with them being separate processes, and, what’s more, rclone offers a different set of handy options for either optimizing (or intentionally throttling) the cloud-based uploads to Backblaze B2."
So you did! Sorry, hadn't read the post beforehand. Oh, and I too mourned the loss of CrashPlan. Being in Canada, I didn't have the option offered to have a restore drive sent if needed, but thought it was a brilliant idea. On the other hand, I think Backblaze might!
