Transferring backups from P.sh to S3

Questions & Answers
#1

I think this would make a good how to guide.

Asking here first. I understand I can install s3cmd or aws-cli. Is there any examples kicking around?

#2

Do you mean backups taken by the “Backup” button in the UI, or something you would do manually with mysqldump and rsync?

#3

I’m not sure of the format of the P.sh backup. But I assume (like mine) some clients have a need to store backups within their own infra or own specified location. So in my case I mean the database and files dumped and rsynced respectively over to S3 or wherever.

I was able to transfer my PostgreSQL dumps to S3 doing the following:

  1. Create sensitive variables for my AWS credentials
platform variable:create --level=project --name=AWS_ACCESS_KEY_ID --value=<KEY_ID> --json=false --sensitive=true --prefix=env --visible-build=true --visible-runtime=true
platform variable:create --level=project --name=AWS_SECRET_ACCESS_KEY --value=<ACCESS_KEY> --json=false --sensitive=true --prefix=env --visible-build=true --visible-runtime=true
  1. Since PostgreSQL comes with a default password main, I created another sensitive environment variable PGPASSWORD to set up the dump cron job
platform variable:create --level=project --name=PGPASSWORD --value=main --json=false --sensitive=true --prefix=env --visible-build=true --visible-runtime=true
  1. I created a mount to save the dumps to in my .platform.app.yaml 
mounts:
    'backups':
        source: local
        source_path: backups
  1. Installed the awscli in my build hook
        if [ ! -z "$AWS_ACCESS_KEY_ID" ] && [ ! -z "$AWS_SECRET_ACCESS_KEY" ]; then
            pip install futures
            pip install awscli --upgrade --user 2>/dev/null
        fi
  1. Created a cron job that called my forwarding script restricted to master 
crons:
    dumps_to_s3:
        spec: '*/15 * * * *'
        cmd: |
            if [ "$PLATFORM_BRANCH" = master ]; then
                ./cron/forward_dumps_s3.sh
            fi
  1. Then included a script to perform the dumps and AWS syncs every 15 minutes
#!/usr/bin/env bash

TODAY_DATE=$(date +%Y-%m-%d-%H:%M:%S)
DUMP_FILE=${TODAY_DATE}-DUMP.sql

DB_HOST="database.internal"
DB_PORT=5432
DB_USER="main"
DUMP_LOC="backups"

AWS_BUCKET=<your bucket name>
AWS_FOLDER=<bucket folder name>

pg_dump --host=$DB_HOST --port=$DB_PORT --username=$DB_USER --file=$DUMP_LOC/$DUMP_FILE

aws s3 sync ~/$DUMP_LOC s3://$AWS_BUCKET/$AWS_FOLDER/
