# Make sure to:
|
|
# 1) Name this file `backup.sh` and place it in /home/ec2-user (or symlink it)
|
|
# 2) Run sudo apt-get install awscli to install the AWSCLI
|
|
# 3) Run aws configure (enter s3-authorized IAM user and specify region)
|
|
# 4) Fill in DB host + name
|
|
# 5) Create S3 bucket for the backups and fill it in below (set a lifecycle rule to expire files older than X days in the bucket)
|
|
# 6) Run chmod +x backup.sh
|
|
# 7) Test it out via ./backup.sh
|
|
