Scheduling backups in a remote server

This page describes how to schedule backups for Cassandra without the Cloud Storage. In this method, backups are stored on a remote server specified by you instead of a Cloud Storage bucket. Apigee uses SSH to communicate with the remote server.

You must schedule the backups as cron jobs. Once a backup schedule has been applied to your hybrid cluster, a Kubernetes backup job is periodically executed according to the schedule in the runtime plane. The job triggers a backup script on each Cassandra node in your hybrid cluster that collects all the data on the node, creates an archive (compressed) file of the data, and sends the archive to the server specified in your overrides.yaml file.

The following steps include common examples for completing specific tasks, like creating an SSH key pair. Use the methods that are appropriate to your installation.

The procedure has the following parts:

Set up the server and SSH

  1. Designate a Linux or Unix server for your backups. This server must be reachable using SSH from your Apigee hybrid runtime plane. It must have enough storage for your backups.
  2. Set up an SSH server on the server, or ensure that it has a secure SSH server configured.
  3. Create an SSH key pair and store the private key file in a path that is accessible from your hybrid runtime plane. You must use a blank password for your key pair or the backup will fail. For example:
    ssh-keygen -t rsa -b 4096 -C
      Enter file in which to save the key (/Users/exampleuser/.ssh/id_rsa): $APIGEE_HOME/hybrid-files/certs/ssh_key
      Enter passphrase (empty for no passphrase):
      Enter same passphrase again:
      Your identification has been saved in ssh_key
      Your public key has been saved in
      The key fingerprint is:
      The key's randomart image is:
      +---[RSA 4096]----+
      |          +.  ++X|
      |     .   . o.=.*+|
      |    . o . . o==o |
      |   . . . =oo+o...|
      |  .     S +E oo .|
      |   . .   .. . o .|
      |    . . .  . o.. |
      |     .  ...o ++. |
      |      .. .. +o+. |
  4. Create a user account on the backup server with the name apigee. Make sure the new apigee user has a home directory under /home.
  5. On the backup server, create an ssh directory in the new /home/apigee directory.
  6. Copy the public key ( in the previous example) into a file named authorized_keys in the new /home/apigee/ssh directory. For example:
    cd /home/apigee
    mkdir .ssh
    cd .ssh
    vi authorized_keys
  7. On your backup server, create a backup directory within the /home/apigee/ directory. The backup directory can be any directory as long as the apigee user has access to it. For example:
    cd /home/apigee
    mkdir cassandra-backup
  8. Test the connection. You need to make sure that your Cassandra pods can connect to your backup server using SSH:
    1. Log into the shell of your Cassandra pod. For example:
      kubectl exec -it -n apigee APIGEE_CASSANDRA_DEFAULT_0 -- /bin/bash

      Where APIGEE_CASSANDRA_DEFAULT_0 is the name of a Cassandra pod. Change this to the name of the pod you want to connect from.

    2. Connect by SSH to your backup server, using the server IP address:
      ssh apigee@BACKUP_SERVER_IP

Set the schedule and destination for backup

You set the schedule and destination for backups in your overrides.yaml file.

  1. Add the following parameters to your overrides.yaml file:


        enabled: true
        keyFile: "PATH_TO_PRIVATE_KEY_FILE"
        server: "BACKUP_SERVER_IP"
        storageDirectory: "/home/apigee/BACKUP_DIRECTORY"
        cloudProvider: "HYBRID" # required verbatim "HYBRID" (all caps)
        schedule: "SCHEDULE"


        enabled: true
        keyFile: "/Users/exampleuser/apigee-hybrid/hybrid-files/service-accounts/private.key"
        server: ""
        storageDirectory: "/home/apigee/cassbackup"
        cloudProvider: "HYBRID"
        schedule: "0 2 * * *"


    Property Description
    backup:enabled Backup is disabled by default. You must set this property to true.


    The path on your local file system to the SSH private key file (named ssh_key in the step where you created the SSH key pair).



    The IP address of your backup server.



    The name of the backup directory on your backup server. This must be a directory within home/apigee (the backup directory is named cassandra_backup in the step where you created the backup directory).



    For a Cloud Storage backup, set the property to GCP. For example, cloudProvider: "GCP".

    For a remote server backup, set the property to HYBRID. For example, cloudProvider: "HYBRID".



    The time when the backup starts, specified in standard crontab syntax. Default: 0 2 * * *

  2. Use apigeectl to apply the backup configuration to the storage scope of your cluster:
    $APIGEECTL_HOME/apigeectl --datastore -f YOUR_OVERRIDES_FILE

    Where YOUR_OVERRIDES_FILE is the path to the overrides file you just edited.

  3. Verify the backup job. For example:
    kubectl get cronjob -n apigee
    NAME                      SCHEDULE     SUSPEND   ACTIVE   LAST SCHEDULE   AGE
    apigee-cassandra-backup   33 * * * *   False     0        <none>          94s
