# Script: nextcloud_backup.sh
|
|
# Description: This script securely backs up NextCloud to a designated
|
|
# mounted drive using rsync. It includes pre-run checks to ensure
|
|
# the source files and destination are valid, and sends ntfy
|
|
# notifications for each task.
|
|
# Usage: sudo ./nextcloud_backup.sh
|
|
# Notes: This script may require sudo/root privileges to access files.
