I use dirvish a text based cron enabled rsync front end. Read dirvish.org for details about it.

I use this to clone and hold time based backups to external disks which I can verify or use offsite.

Rock solid for years.

Here's some I have even reread.

• The chronicles of Thomas Covenant the Unbeliever. By Stephen R. Donaldson. 10 books
• The Galactic Center Saga by Gregory Benford. 6 books
• The Culture Series by Iain M. Banks 10 books
• LOTR

Love the Murderbot series too.
