Backup and Restore Site and DB snapshots

1. All-in-one Snapshot backup script (preferred method)

A. Create environment variables in your shell session for

  1. The Jira build ticket id

  2. The cloud.gov space to which deployment is taking place

  3. A string indicating the type of backup (e.g. pre or post deployment, emergency, interrim, etc.)

     TICKET=USAGOV-999
 SPACE=prod
 SUFFIX=pre-deploy

B. Ensure you are in the Cloud Foundry space which you want to backup e.g:

    cf target -s $SPACE

C. Run the all-in-one backup script.

This will fail if the current CF space does not match the SPACE env var. This will wait for a currently-running tome job to complete before proceeding. It will wait up to 25 minutes. It will then disable tome and enable Drupal maintenance mode while the backup is performed, restoring them when complete

    # dryrun='--dryrun'
    bin/snapshot-backups/local-snapshot-backup $dryrun $SPACE $TICKET $SUFFIX

D. Make a note of the snapshot tag string emitted by the previous script, and set an environment variable for it.

The string will look like USAGOV-999.prod.1234.pre-deploy or similar. It is made up of the TICKET, SPACE and SUFFIX environment variables, and a number - representing the CircleCI build number for the deployment being backed up

  SNAPTAG=USAGOV-999.prod.1234.pre-deploy

E. Run the all-in-one snapshot download script (downloads the snapshot zips to the current directory)

    # dryrun='--dryrun'
    bin/snapshot-backups/local-snapshot-download $dryrun $SPACE $SNAPTAG

F. Copy the downloaded snapshot zips to the appropriate Google Drive folders:

1. All-in-one Snapshot Deploy/Restore script (preferred method)

Please note that in a disaster recovery situation, the Cloud Foundry spaces will need to be set up and working, prior to performing these restore steps.

A. Create an environment variable in your shell session for the CF space you wish to restore into

    SPACE=prod

B. Download the latest snapshot zips from the appropriate Google Drive folders, into the root directory of your local environment

Make sure each of the files has the same snapshot tag (the beginning of the file names should all match. eg USAGOV-999.prod.1234.pre-deploy)

C. Make a note of the snapshot tag string common to the files you downloaded from Google Drive, and set an environment variable for it

  SNAPTAG=USAGOV-999.prod.1234.pre-deploy

D. Ensure you are in the Cloud Foundry Space to which you wish to deploy

    cf target -s $SPACE

E. Run the all-in-one restore script:

  # dryrun='--dryrun'
  bin/snapshot-backups/local-snapshot-deploy $dryrun $SPACE $SNAPTAG
