Thanks for your comment. Actually, Client-Side-Encrypted-Backups is different in that a backup cannot be created unless tar, ccrypt and sftp on the user's machine execute smoothly. In your example, in the case of a user's local drive going bad during a backup, one of these (tar, ccrypt, sftp) would fail causing the backup to not be created. All files that show up in the completed_backups log file are golden backups and can be restored at anytime. For me, I have been exclusively using Client-Side-Encrypted-Backups to do all of my backups (since 2011). I don't ever recall seeing an issue in all of those years. It's been very reliable.
