Backup Architecture details

• we use restic to produce small & encrypted backups
• backup is scheduled at schedule: "10 23 * * *"
• Cloud stores files on /var/jira, these files are backuped. If you create a jira xml backup located in /var/jira this file will also be backed up.
• postgres db is backed up as pgdump

Manual init the restic repository for the first time

1. Scale backup-restore deployment up:
   kubectl scale deployment backup-restore --replicas=1
2. exec into pod and execute restore pod
   kubectl exec -it backup-restore -- /usr/local/bin/init.sh
3. Scale backup-restore deployment down:
   kubectl scale deployment backup-restore --replicas=0

Manual backup the restic repository for the first time

1. Scale Cloud deployment down:
   kubectl scale deployment cloud --replicas=0
2. Scale backup-restore deployment up:

3. exec into pod and execute restore pod
   kubectl exec -it backup-restore -- /usr/local/bin/backup.sh

   kubectl scale deployment backup-restore --replicas=0
5. Scale Cloud deployment up:
   kubectl scale deployment cloud --replicas=1

Manual restore

1. Scale Cloud deployment down:
   kubectl scale deployment cloud --replicas=0
2. Scale backup-restore deployment up:
   kubectl scale deployment backup-restore --replicas=1
3. apply backup-and-restore pod:
   kubectl apply -f src/main/resources/backup/backup-restore-deployment.yaml
4. exec into pod and execute restore pod
   kubectl exec -it backup-restore -- /usr/local/bin/restore.sh
