Script for automation

PostgreSQL

Backup and upload to S3

#!/bin/bash

# Variables to modify
username="your_username"
database="your_database"
bucket_name="your_bucket_name"

# Backup PostgreSQL database
pg_dump -U $username -d $database > backup.sql

# Send to S3
s3cmd put backup.sql s3://$bucket_name/backup.sql

Retrieve from S3 and restore

#!/bin/bash

# Variables to modify
bucket_name="your_bucket_name"
username="your_username"
database="your_database"

# Recovery from S3
s3cmd get s3://$bucket_name/backup.sql /tmp/backup.sql

# Restore PostgreSQL database
psql -U $username -d $database < /tmp/backup.sql

MariaDB

Backup and upload to S3

#!/bin/bash

# Variables to modify
username="your_username"
database="your_database"
bucket_name="your_bucket_name"

# Backup MariaDB database
mysqldump -u $username -p $database > backup.sql

# Send to S3
s3cmd put backup.sql s3://$bucket_name/backup.sql

# Delete backup file
rm backup.sql

Recover from S3 and restore

#!/bin/bash

# Variables to modify
bucket_name="your_bucket_name"
username="your_username"
database="your_database"

# Retrieve from S3
s3cmd get s3://$bucket_name/backup.sql /tmp/backup.sql

# Restore MariaDB database
mysql -u $username -p $database < /tmp/backup.sql

MySQL

Backup and upload to S3

#!/bin/bash

# Variables to modify
username="your_username"
database="your_database"
bucket_name="your_bucket_name"

# MySQL database backup
mysqldump -u $username -p $database > backup.sql

# Send to S3
s3cmd put backup.sql s3://$bucket_name/backup.sql

Retrieve from S3 and restore

#!/bin/bash

# Variables to modify
bucket_name="your_bucket_name"
username="your_username"
database="your_database"

# Retrieve from S3
s3cmd get s3://$bucket_name/backup.sql /tmp/backup.sql

# Restore MySQL database
