#2Perfect? Ha.
Wrong ps grep usage. MacOS specific. No shell quoting.
At least he doesn't advocate rm -rf / by an incorrect usage of --delete.

#3Too complicated to even try to read. Rsync is great but I've switched to Borg for backups. Borg isn't perfect but it is a higher level approach to backups, as it were. Hetzner recently dropped the price of their Storage Box backup product to about 2 euro per TB per month, and Borg works nicely with it. Borg encrypts all the backup contents and conceals the metadata on the backup server, and yet you can (with the encryption passphrase) mount the backup archive as a read-only file system through FUSE and access it through normal file navigation. It is impressive.

A shell on a Mac is the "we have x at home" meme to me. Very frustrating.

Is it possible to use it as a read/write mounted drive on macOS?

#6rsnapshot[1] is what I used on FreeBSD with a snapshot. It is like a well-tested version of the author's rsync and ssh blog post. I have a blog post here[2] describing my setup. It saved my bacon multiple times. Also, rsnapshot works in pull mode, so no client is needed on my Linux/macOS desktop or server except ssh and rsync.

#7What seems like a long time ago, I was working at a place that used Linux, but not really any Linux experts. They had backup scripts that assumed (and did not check) that you would connect an external drive. If you didn't, the script would gladly copy files to /mnt/usbdrive, and if the server was full enough, backing up itself to itself would fill the drive and bad things would then happen.
There was no email notification if the backup completed or failed, or even started to run. There was no notification of how long it took, how much data was backed up, etc.
There were plenty of incidents of data loss.

I think restic[1] does provide this.

Yep. We use rsnapshot with btrfs snapshots on Debian / Ubuntu. You can set up multiple generations easily. Efficient storage using hard links.
Very reliable.

>Storage Box backup product
The script here really only makes sense for servers you physically own. You wouldn't accept SSH access from a key located on a plain VPS, right? Also this script doesn't seem to encrypt the data at all!! Very dangerous on a VPS.
