How to backup Linux to Amazon S3 step by step

Performing a Linux backup to Amazon S3 involves several steps. Here's a guide to accomplish Linux backup:

Prerequisites for executing Linux backup

• ssh access to your server
• sudo permissions
• an amazon s3 account
• AWS-CLI installed

Steps to backup Linux server to Amazon S3

1. Configure the S3 storage setting: Set up the s3cmd to use bucket. Type the following command to process:

aws configure

2. Create an S3 bucket in Amazon from command line: Using AWS-CLI, create a bucket to upload files with just one straightforward command:

aws s3 mb s3://myserver_backups

3. Write the backup script: First, you need a place to keep the backups, for example:

mkdir /var/www/_backups

4. Create a backup.sh file in home directory:

#!/bin/sh

THEDBUSER="myDatabaseUsername"

THEDBPW="myDatabasePassword"

THEDATE=`date +%d%m%y%H%M`

# Export all the databases

mysqldump -u $THEDBUSER -p${THEDBPW} --all-databases > /var/www/_backups/dbbackup_${THEDATE}.sql

# Remove backups older than 31 days

find /var/www/_backups/site* -mtime +31 -exec rm {} \;

find /var/www/_backups/apache* -mtime +31 -exec rm {} \;

find /var/www/_backups/db* -mtime +31 -exec rm {} \;

# Export files

tar czf /var/www/_backups/sitebackup_${THEDATE}.tar -C / var/www/docs

# Export the Apache vhosts configuration

tar czf /var/www/_backups/apachebackup_${THEDATE}.tar -C / etc/apache2/sites-available

# Sync to amazon. With the 'delete' option, the files removed from

# /var/www/_backups will be removed from the bucket as well

aws s3 sync /var/www/_backups s3://my-bucket-name –delete

5. Make that script executable with the following command and test it.

chmod +x backup.sh

./backup.sh

6. If all is well, edit your crontab with ‘crontab -e’ and append something like:

0 3 * * * /path/to/backup.sh > /dev/null 2>&1

Conclusion

In conclusion, backing up Linux systems to Amazon S3 provides a reliable and secure solution for protecting your valuable data. The advantages of leveraging Amazon S3 make it an ideal choice for Linux backup storage. By following the outlined steps, you can ensure the accessibility and integrity of their Linux system backups.
