# MongoDB Online Dump Script (Standalone Docker)
|
|
# ==============================================================================
|
|
#
|
|
# PURPOSE:
|
|
# Creates an online backup of only the 'utility-bills' database using mongodump.
|
|
# The database server remains running during the backup process.
|
|
#
|
|
# WHEN TO USE:
|
|
# - For standalone Docker deployments (not Docker Swarm)
|
|
# - When you need a quick backup without downtime
|
|
# - When you only need the database content, not the full volume
|
|
#
|
|
# BACKUP TYPE:
|
|
# - Online (hot) backup - DB server keeps running
|
|
# - Database-level backup - only 'utility-bills' database
|
|
# - Creates compressed archive (.tar.gz) using mongodump
|
|
#
|
|
# OUTPUT:
|
|
# - Backup files stored in: ./mongo-backup/
|
|
# - Filename format: utility-bills-dump-YYYY-MM-DD_HH-MM.tar.gz
|
|
# - Log file: ./mongo-backup/db-dump-db-standalone.log
|
|
# - Automatic rotation: keeps newest 7 backups (configurable via KEEP env var)
|
|
#
|
|
# USAGE:
|
|
# ./db-dump--standalone.sh
|
|
# KEEP=10 ./db-dump--standalone.sh # Keep 10 backups instead of 7
|
