> Can I sign up somewhere to get notified when "back up to your own cloud destinations" is complete?
If you edit your backup, you can create a custom hook (https://relicabackup.com/docs/backup-hooks). We plan to implement email notifications when such events occur as well.
> As great as cloud backup solutions are, the weak point is always getting things out.
We're implementing "Bring your own cloud" now, so you can provide your own S3-compatible, SFTP, Azure, or Google storage (more to come). This feature is almost done.
> Also, trust and security are going to be huge.
Backups are encrypted on the client, and the key is kept on your local device (don't lose it!). We can't access your data, and even your file selection is encrypted.
