From b8a3c982970e5ab3fa277a0056fc3a842b90d482 Mon Sep 17 00:00:00 2001 From: Peter Wood Date: Sun, 25 May 2025 23:35:47 -0400 Subject: [PATCH] feat: Add enhanced backup-media script and documentation - Introduced demo-enhanced-backup.sh to showcase new features. - Created backup-media-enhancement-summary.md for a side-by-side comparison of original and enhanced scripts. - Developed enhanced-media-backup.md detailing features, usage, configuration, and error handling of the new backup script. - Enhanced logging, error handling, and performance monitoring capabilities. - Added support for multiple media services with improved safety and maintenance features. --- README.md | 195 ++++-- backup-media.sh | 794 ++++++++++++++++++++++- demo-enhanced-backup.sh | 126 ++++
