Introduction

This backup system is a straightforward containerized solution designed to back up one or more supported databases to a secondary location.

Supported Databases & Secondary Locations

Databases

• PostgresSQL
• MongoDB
• MariaDB
• MSSQL - Currently MSSQL requires that the nfs db volume be shared with the database for backups to function correctly.

Secondary Locations

• OCIO backup infrastructure
• Amazon S3 (S3 Compatible / OCIO Object Store)
• FTP Server

Backup Container Options

You have the option to run the Backup Container for supported databases either separately or in a mixed environment. If you choose the mixed environment, please follow these guidelines:

1. It is required to use the recommended backup.conf configuration.
2. Within the backup.conf file, make sure to specify the DatabaseType for each listed database.
3. For each type of supported backup container being used, you will need to create a build and deployment configuration.
4. Make sure to mount the same backup.conf file (ConfigMap) to each deployed container.

These steps will help ensure the smooth operation of the backup system.

Backups in OpenShift

This project provides you with a starting point for integrating backups into your OpenShift projects. The scripts and templates provided in the openshift directory are compatible with the openshift-developer-tools scripts. They help you create an OpenShift deployment or cronjob called backup in your projects that runs backups on databases within the project environment. You only need to integrate the scripts and templates into your project(s), the builds can be done with this repository as the source.

As an alternative to using the command line interface oc (OpenShift CLI), you can integrate the backup configurations (Build and Deployment templates, override script, and config) directly into your project configuration and manage the publishing and updating of the Build and Deployment configurations using the BCDevOps/openshift-developer-tools scripts. An example can be found in the bcgov/orgbook-configurations repository under the backup templates folder.

Simplified documentation on how to use the tools can be found here. All scripts support a -c option that allows you to perform operations on a single component of your application such as the backup container. In the orgbook-configurations example above, note the -c backup argument supplied.

Following are the instructions for running the backups and a restore.

Storage

The backup container utilizes two volumes: one for storing the backups and another for restore/verification testing. The deployment template deliberately separates these volumes.

The upcoming sections on storage will provide you with recommendations and limitations regarding the storage classes.

Backup Storage Volume

We recommend using the netapp-file-backup storage class for the backup Persistent Volume Claim (PVC). This storage class is supported by the standard OCIO backup infrastructure and has a default quota of 25Gi. If you require additional storage, please submit an iStore request to adjust the quota accordingly. The backup retention policy for the backup infrastructure is as follows:

• Backup:

  • Daily: Incremental
  • Monthly: Full
• Retention: 90 days

If you are utilizing S3 storage or the corporate S3 compatible storage, you may not need to use the netapp-file-backup storage class. These systems are already replicated and highly redundant. In such cases, we recommend using the following storage classes:

• netapp-file-standard for backup storage
• netapp-file-standard for restore/verification storage

To implement this, create a PVC using the the appropriate storage class and mount it to your pod at the /backups mount point. Or, if you're using the provided deployment template, update or override the BACKUP_VOLUME_STORAGE_CLASS parameter.

For more detailed information, please visit the DevHub page.

Restore / Verification Storage Volume

The restore/verification volume should use the default storage class netapp-file-standard. Please avoid using netapp-file-backup as it is not suitable for transient workloads. The provided deployment template will automatically provision this volume when it is published.

Ensure that the volume is large enough to accommodate your largest database. You can set the size by updating or overriding the VERIFICATION_VOLUME_SIZE parameter in the provided OpenShift template.

Storage Performance

Our PVC are supported by NetApp storage. It's important to note that the performance of the storage is not affected by the storage class chosen.

Deployment / Configuration

Together, the scripts and templates provided in the openshift directory will automatically deploy the backup app as described below. The backup-deploy.overrides.sh script generates the deployment configuration necessary for the backup.conf file to be mounted as a ConfigMap by the backup container.

The following environment variables are defaults used by the backup app.

NOTE: These environment variables MUST MATCH those used by the database container(s) you are planning to backup.

backup.conf

Using this default configuration you can easily back up a single postgres database, however we recommend you extend the configuration and use the backup.conf file to list a number of databases for backup and even set a cron schedule for the backups.

When using the backup.conf file the following environment variables are ignored, since you list all of your host/database pairs in the file; DATABASE_SERVICE_NAME, DATABASE_NAME. To provide the credentials needed for the listed databases you extend the deployment configuration to include hostname_USER and hostname_PASSWORD credential pairs which are wired to the appropriate secrets (where hostname matches the hostname/servicename, in all caps and underscores, of the database). For example, if you are backing up a database named wallet-db/my_wallet, you would have to extend the deployment configuration to include a WALLET_DB_USER and WALLET_DB_PASSWORD credential pair, wired to the appropriate secrets, to access the database(s) on the wallet-db server.

Cron Mode

The backup container supports running the backups on a cron schedule. The schedule is specified in the backup.conf file. Refer to the backup.conf file for additional details and examples.

Cronjob Deployment / Configuration / Constraints

This section describes the configuration of an OpenShift CronJob this is different than the Cron Mode supported by the container when deployed in "long running" mode.

The cronjob object can be deployed in the same manner as the application, and will also have a dependency on the image built by the build config. The main constraint for the cronjob objects is that they will require a configmap in place of environment variables and does not support the backup.conf for multiple database backups in the same job. In order to backup multiple databases, create multiple cronjob objects with their associated configmaps and secrets.

The following variables are supported in the first iteration of the backup cronjob:

The following variables are NOT supported:

The scheduled job does not yet support the FTP environment variables.

Resources

The backup-container is assigned with Best-effort resource type (setting zero for request and limit), which allows the resources to scale up and down without an explicit limit as resource on the node allow. It benefits from large bursts of recourses for short periods of time to get things more quickly. After some time of running the backup-container, you could then set the request and limit according to the average resource consumption.

Multiple Databases

When backing up multiple databases, the retention settings apply to each database individually. For instance if you use the daily strategy and set the retention number(s) to 5, you will retain 5 copies of each database. So plan your backup storage accordingly.

An example of the backup container in action can be found here; example log output

Backup Strategies

The backup app supports two backup strategies, each are explained below. Regardless of the strategy backups are identified using a core name derived from the host/database specification and a timestamp. All backups are compressed using gzip.

Daily

The daily backup strategy is very simple. Backups are created in dated folders under the top level /backups/ folder. When the maximum number of backups (NUM_BACKUPS) is exceeded, the oldest ones are pruned from disk.

For example (faked):

================================================================================================================================

Rolling

The rolling backup strategy provides a bit more flexibility. It allows you to keep a number of recent daily backups, a number of weekly backups, and a number of monthly backups.

• Daily backups are any backups done Monday through Saturday.
• Weekly backups are any backups done at the end of the week, which we're calling Sunday.
• Monthly backups are any backups done on the last day of a month.

There are retention settings you can set for each. The defaults provide you with a week's worth of daily backups, a month's worth of weekly backups, and a single backup for the previous month.

Although the example does not show any weekly or monthly backups, you can see from the example that the folders are further broken down into the backup type.

================================================================================================================================

Using the Backup Script

The backup script has a few utility features built into it. For a full list of features and documentation run backup.sh -h.

Features include:

• The ability to list the existing backups, backup.sh -l
• Listing the current configuration, backup.sh -c
• Running a single backup cycle, backup.sh -1

• Restoring a database from backup, backup.sh -r <databaseSpec/> [-f <backupFileFilter>]

  • Restore mode will allow you to restore a database to a different location (host, and/or database name) provided it can contact the host and you can provide the appropriate credentials.

• Verifying backups, backup.sh [-s] -v <databaseSpec/> [-f <backupFileFilter>]

  • Verify mode will restore a backup to the local server to ensure it can be restored without error. Once restored a table query is performed to ensure there was at least one table restored and queries against the database succeed without error. All database files and configuration are destroyed following the tests.

Using Backup Verification

The backup script supports running manual or scheduled verifications on your backups; backup.sh [-s] -v <databaseSpec/> [-f <backupFileFilter>]. Refer to the script documentation backup.sh -h, and the configuration documentation, backup.conf, for additional details on how to use this feature.

Using the FTP backup

• The FTP backup feature is enabled by specifying the FTP server URL FTP_URL.
• The FTP server must support FTPS.
• Path can be added to the URL. For example, the URL can be ftp://ftp.gov.bc.ca/schoolbus-db-backup/. Note that when adding path, the URL must be ended with / as the example.
• The username and password must be populated in the secret key. Refer to the deployment configuration section.
• There is a known issue for FTPS with Windows 2012 FTP. http://redoubtsolutions.com/fix-the-supplied-message-is-incomplete-error-when-you-use-an-ftps-client-to-upload-a-file-in-windows/

Using the Webhook Integration

The Webhook integration feature is enabled by specifying the webhook URL, WEBHOOK_URL, in your configuration. It's recommended that you also provide values for ENVIRONMENT_FRIENDLY_NAME and ENVIRONMENT_NAME, so you can better identify the environment from which the messages originate and do things like produce links to the environment.

The Webhook integration feature was built with Rocket.Chat in mind and an integration script for Rocket.Chat can be found in rocket.chat.integration.js. This script was developed to support the BC OpenShift Pathfinder environment and will format the notifications from the backup script into Rocket.Chat messages (examples below). If you provide values for the environment name (ENVIRONMENT_FRIENDLY_NAME and ENVIRONMENT_NAME) hyperlinks will be added to the messages to link you to the pathfinder project console.

Sample Message:

Sample Error Message:

For information on how setup a webhook in Rocket.Chat refer to Incoming WebHook Scripting. The Webhook URL created during this process is the URL you use for WEBHOOK_URL to enable the Webhook integration feature.

Database Plugin Support

The backup container uses a plugin architecture to perform the database specific operations needed to support various database types.

The plugins are loaded dynamically based on the container type. By default the backup.null.plugin will be loaded when the container type is not recognized.

To add support for a new database type:

1. Update the getContainerType function in backup.container.utils to detect the new type of database.
2. Using the existing plugins as reference, implement the database specific scripts for the new database type.
3. Using the existing docker files as reference, create a new one to build the new container type.
4. Update the build and deployment templates and their documentation as needed.
5. Update the project documentation as needed.
6. Test, test, test.
7. Submit a PR.

Plugin Examples:

• backup.postgres.plugin

  • Postgres backup implementation.

• backup.mongo.plugin

  • Mongo backup implementation.

• backup.mssql.plugin

  • MSSQL backup implementation.

• backup.mariadb.plugin

  • MariaDB backup implementation. This plugin should also work with mysql, but is currently untested.

• backup.null.plugin

  • Sample/Template backup implementation that simply outputs log messages for the various operations.

Backup

The following sections describes (some) postgres specific implementation, however the steps are generally the same between database implementations.

The purpose of the backup app is to do automatic backups. Deploy the Backup app to do daily backups. Viewing the Logs for the Backup App will show a record of backups that have been completed.

The Backup app performs the following sequence of operations:

1. Create a directory that will be used to store the backup.
2. Use the pg_dump and gzip commands to make a backup.
3. Cull backups more than $NUM_BACKUPS (default 31 - configured in deployment script)
4. Wait/Sleep for a period of time and repeat

Note that with the pod deployment, we support cron schedule(s) or the legacy mode (which uses a simple "sleep") to run the backup periodically. With the OpenShift Scheduled Job deployment, use the backup-cronjob.yaml template and set the schedule via the OpenShift cronjob object SCHEDULE template parameter.

A separate pod is used vs. having the backups run from the Postgres Pod for fault tolerant purposes - to keep the backups separate from the database storage. We don't want to, for example, lose the storage of the database, or have the database and backups storage fill up, and lose both the database and the backups.

Immediate Backup:

Execute a single backup cycle with the pod deployment

• Check the logs of the Backup pod to make sure a backup isn't run right now (pretty unlikely...)
• Open a terminal window to the pod

• Run backup.sh -1

  • This will run a single backup cycle and exit.

Execute an on demand backup using the scheduled job

• Run the following: oc create job ${SOMEJOBNAME} --from=cronjob/${BACKUP_CRONJOB_NAME}

  • example: oc create job my-backup-1 --from=cronjob/backup-postgresql
  • this will run a single backup job and exit.
  • note: the jobs created in this manner are NOT cleaned up by the scheduler like the automated jobs are.

Restore

The backup.sh script's restore mode makes it very simple to restore the most recent backup of a particular database. It's as simple as running a the following command, for example (run backup.sh -h for full details on additional options);

backup.sh -r postgresql/TheOrgBook_Database

Following are more detailed steps to perform a restore of a backup.

1. Log into the OpenShift Console and log into OpenShift on the command shell window.

   1. The instructions here use a mix of the console and command line, but all could be done from a command shell using "oc" commands.

2. Scale to 0 all Apps that use the database connection.

   1. This is necessary as the Apps will need to restart to pull data from the restored backup.
   2. It is recommended that you also scale down to 0 your client application so that users know the application is unavailable while the database restore is underway.
   3. A nice addition to this would be a user-friendly "This application is offline" message - not yet implemented.
3. Restart the database pod as a quick way of closing any other database connections from users using port forward or that have rsh'd to directly connect to the database.

4. Open an rsh into the backup pod:

   1. Open a command prompt connection to OpenShift using oc login with parameters appropriate for your OpenShift host.
   2. Change to the OpenShift project containing the Backup App oc project <Project Name>
   3. List pods using oc get pods
   4. Open a remote shell connection to the backup pod. oc rsh <Backup Pod Name>

5. In the rsh run the backup script in restore mode, ./backup.sh -r <DatabaseSpec/>, to restore the desired backup file. For full information on how to use restore mode, refer to the script documentation, ./backup.sh -h. Have the Admin password for the database handy, the script will ask for it during the restore process.

   1. The restore script will automatically grant the database user access to the restored database. If there are other users needing access to the database, such as the DBA group, you will need to additionally run the following commands on the database pod itself using psql:
   2. Get a list of the users by running the command \du
   3. For each user that is not "postgres" and $POSTGRESQL_USER, execute the command GRANT SELECT ON ALL TABLES IN SCHEMA public TO "<name of user>";
   4. If users have been set up with other grants, set them up as well.

6. Verify that the database restore worked

   1. On the database pod, query a table - e.g the USER table: SELECT * FROM "SBI_USER"; - you can look at other tables if you want.
   2. Verify the expected data is shown.
7. Exit remote shells back to your local command line

8. From the Openshift Console restart the app:

   1. Scale up any pods you scaled down and wait for them to finish starting up. View the logs to verify there were no startup issues.
9. Verify full application functionality.

Done!

Network Policies

The default backup-container template contains a basic Network Policy that is designed to be functioning out-of-the-box for most standard deployments. It provides:

• Internal traffic authorization towards target databases: for this to work, the target database deployments must be in the same namespace/environment AND must be labelled with backup=true.

The default Network Policy is meant to be a "one size fits all" starter policy to facilitate standing up the backup-container in a new environment. Please consider updating/tweaking it to better fit your needs, depending on your setup.

Example Deployments

The following outlines the deployment of a simple backup of three PostgreSQL databases in the same project namespace, on OCP v4.x.

1. As per OCP4 docs, 25G of the storage class netapp-file-backup is the default quota. If this is insufficient, you may request more.
2. git clone https://github.com/BCDevOps/backup-container.git && cd backup-container.

Create the image.

oc -n 599f0a-tools process -f ./openshift/templates/backup/backup-build.yaml \
  -p NAME=nrmsurveys-bkup OUTPUT_IMAGE_TAG=v1 | oc -n 599f0a-tools create -f -

3. Configure (./config/backup.conf) (listing your database(s), and setting your cron schedule).

postgres=eaofider-postgresql:5432/eaofider
postgres=pawslimesurvey-postgresql:5432/pawslimesurvey

0 1 * * * default ./backup.sh -s
0 4 * * * default ./backup.sh -s -v all

4. Configure references to your DB credentials in backup-deploy.yaml, replacing the boilerplate DATABASE_USER and DATABASE_PASSWORD environment variables.

- name: EAOFIDER_POSTGRESQL_USER
  valueFrom:
    secretKeyRef:
      name: eaofider-postgresql
      key: "${DATABASE_USER_KEY_NAME}"
- name: EAOFIDER_POSTGRESQL_PASSWORD
  valueFrom:
    secretKeyRef:
      name: eaofider-postgresql
      key: "${DATABASE_PASSWORD_KEY_NAME}"

Note that underscores should be used in the environment variable names.

5. Create your customized ./openshift/backup-deploy.overrides.param parameter file, if required.
6. Deploy the app; here the example namespace is 599f0a-dev and the app name is nrmsurveys-bkup:

oc -n 599f0a-dev create configmap backup-conf --from-file=./config/backup.conf
oc -n 599f0a-dev label configmap backup-conf app=nrmsurveys-bkup

oc -n 599f0a-dev process -f ./openshift/templates/backup/backup-deploy.yaml \
  -p NAME=nrmsurveys-bkup \
  -p IMAGE_NAMESPACE=599f0a-tools \
  -p SOURCE_IMAGE_NAME=nrmsurveys-bkup \
  -p TAG_NAME=v1 \
  -p BACKUP_VOLUME_NAME=nrmsurveys-bkup-pvc -p BACKUP_VOLUME_SIZE=20Gi \
  -p VERIFICATION_VOLUME_SIZE=5Gi \
  -p ENVIRONMENT_FRIENDLY_NAME='NRM Survey DB Backups' | oc -n 599f0a-dev create -f -

To clean up the deployment

oc -n 599f0a-dev delete pvc/nrmsurveys-bkup-pvc pvc/backup-verification secret/nrmsurveys-bkup secret/ftp-secret dc/nrmsurveys-bkup networkpolicy/nrmsurveys-bkup configmap/backup-conf

To clean up the image stream and build configuration

oc -n 599f0a-dev delete buildconfig/nrmsurveys-bkup imagestream/nrmsurveys-bkup 

The following outlines the deployment of a simple backup of a single MongoDB database with backup validation.

1. Decide on amount of backup storage required. While 25Gi is the default quota limit in BC Gov OCP4 provisioned namespaces for netapp-file-backup-class storage, teams are able to request more. If you are backing up a non-production environment or an environment outside of BC Gov OCP, you can use a different storage class and thus, different default storage quota. This example assumes that you're using 5Gi of netapp-file-backup-class storage.
2. git clone https://github.com/BCDevOps/backup-container.git && cd backup-container.
3. Determine the OpenShift namespace for the image (e.g. abc123-dev), the app name (e.g. myapp-backup), and the image tag (e.g. v1). Then build the image in your -tools namespace.

oc -n abc123-tools process -f ./openshift/templates/backup/backup-build.yaml \
  -p DOCKER_FILE_PATH=Dockerfile_Mongo
  -p NAME=myapp-backup -p OUTPUT_IMAGE_TAG=v1  -p BASE_IMAGE_FOR_BUILD=registry.access.redhat.com/rhscl/mongodb-36-rhel7 | oc -n abc123-tools create -f -

4. Configure ./config/backup.conf. This defines the database(s) to backup and the schedule that backups are to follow. Additionally, this sets up backup validation (identified by -v all flag).

# Database(s)
mongo=myapp-mongodb:27017/mydb

# Cron Schedule(s)
0 1 * * * default ./backup.sh -s
0 4 * * * default ./backup.sh -s -v all

5. Configure references to your DB credentials in backup-deploy.yaml, replacing the boilerplate DATABASE_USER and DATABASE_PASSWORD environment variable names. Note the hostname of the database to be backed up. This example uses a hostname of myapp-mongodb which maps to environement variables named MYAPP_MONGODB_USER and MYAPP_MONGODB_PASSWORD. See the backup.conf section above for more in depth instructions. This example also assumes that the name of the secret containing your database username and password is the same as the provided DATABASE_DEPLOYMENT_NAME parameter. If that's not the case for your service, the secret name can be overridden.

- name: MYAPP_MONGODB_USER
  valueFrom:
    secretKeyRef:
      name: "${DATABASE_DEPLOYMENT_NAME}"
      key: "${DATABASE_USER_KEY_NAME}"
- name: MYAPP_MONGODB_PASSWORD
  valueFrom:
    secretKeyRef:
      name: "${DATABASE_DEPLOYMENT_NAME}"
      key: "${DATABASE_PASSWORD_KEY_NAME}"

6. Deploy the app. In this example, the namespace is abc123-dev and the app name is myapp-backup. Note that the key names within the database secret referencing database username and password are username and password, respectively. If this is not the case for your deployment, specify the correct key names as parameters DATABASE_USER_KEY_NAME and DATABASE_PASSWORD_KEY_NAME. Also note that BACKUP_VOLUME_NAME is from Step 2 above.

oc -n abc123-dev create configmap backup-conf --from-file=./config/backup.conf
oc -n abc123-dev label configmap backup-conf app=myapp-backup

oc -n abc123-dev process -f ./openshift/templates/backup/backup-deploy.yaml \
  -p NAME=myapp-backup \
  -p IMAGE_NAMESPACE=abc123-tools \
