Linux Server Backup Scripts

Bash scripts that snapshot app data and databases, then transfer archives to a remote server over SSH/scp. Designed for Linux hosts but can back up from any environment where these services run.

Included

• NGINX config snapshot
• Orion-Assets static assets
• SQL Server data-directory archive
• PostgreSQL logical dump (pg_dumpall)
• MongoDB dump from container
• Core-Fabric stack archive
• Consolidated Mongo dev stack archiver

Requirements

• Linux host with Bash, tar, gzip, scp
• Docker (for container-based services)
• Remote server with OpenSSH enabled
• .env populated from sample.env

Quick start

cp sample.env .env
chmod +x scripts/*.sh
# test one component
env $(cat .env | xargs) scripts/postgres-backup.sh

Usage

# NGINX
env $(cat .env | xargs) scripts/nginx-backup.sh /etc/nginx/nginx.conf

# Orion-Assets
env $(cat .env | xargs) scripts/orion-assets-backup.sh

# SQL Server
env $(cat .env | xargs) scripts/sqlserver-backup.sh

# PostgreSQL
env $(cat .env | xargs) scripts/postgres-backup.sh

# Mongo (single container)
env $(cat .env | xargs) scripts/mongo-backup.sh

# Core-Fabric tree
env $(cat .env | xargs) scripts/core-fabric-backup.sh

# Mongo dev stacks (pass directory name under $PERSIST_ROOT)
env $(cat .env | xargs) scripts/mongo-dev-backup.sh mongo_dev
env $(cat .env | xargs) scripts/mongo-dev-backup.sh mongo_dev_1

Scheduling

crontab -e
# run nightly at 01:30
30 1 * * * cd /opt/linux-backup-scripts && \
  env $(cat .env | xargs) bash scripts/postgres-backup.sh \
  >/var/log/pg-backup.cron 2>&1

Restore cheat sheet

• PostgreSQL:

  gunzip -c postgres-*.sql.gz | psql -U postgres

• MongoDB:

  tar -xzf mongodb_*.tar.gz && mongorestore dump/

• File archives:

  tar -xzf backup.tar.gz -C <target_dir>

• NGINX conf:

  cp backup-nginx.conf /etc/nginx/nginx.conf
  nginx -t && systemctl reload nginx

Security

• Keep .env out of Git.
• Use a least-privileged SSH account and key authentication.
• Restrict scp destination directories on the remote server.
