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 backup

1. Scale gateway and front deployment down:
   kubectl -n taiga scale deployment taiga-gateway-deployment --replicas=0 kubectl -n taiga scale deployment taiga-front-deployment --replicas=0
2. Scale backup-restore deployment up:
   kubectl -n taiga scale deployment backup-restore --replicas=1
3. exec into pod and execute restore pod
   kubectl -n taiga exec -it backup-restore -- backup.bb
4. Scale backup-restore deployment down:
   kubectl -n taiga scale deployment backup-restore --replicas=0
5. Scale gateway and front deployment up:
   kubectl -n taiga scale deployment taiga-gateway-deployment --replicas=1 kubectl -n taiga scale deployment taiga-front-deployment --replicas=1

Manual restore

1. Scale gateway and front deployment down:
   kubectl -n taiga scale deployment taiga-gateway-deployment --replicas=0 kubectl -n taiga scale deployment taiga-front-deployment --replicas=0
2. Scale backup-restore deployment up:
   kubectl -n taiga scale deployment backup-restore --replicas=1
3. exec into pod and execute restore pod
   kubectl -n taiga exec -it backup-restore -- restore.bb
4. Scale backup-restore deployment down:
   kubectl -n taiga scale deployment backup-restore --replicas=0
5. Scale gateway and front deployment up:
   kubectl -n taiga scale deployment taiga-gateway-deployment --replicas=1 kubectl -n taiga scale deployment taiga-front-deployment --replicas=1

Change Password

1. Check restic-new-password env is set in backup deployment

   kind: Deployment
   metadata:
     name: backup-restore
   spec:
       spec:
         containers:
         - name: backup-app
           env:
           - name: RESTIC_NEW_PASSWORD_FILE
             value: /var/run/secrets/backup-secrets/restic-new-password
   

2. Add restic-new-password to secret

   kind: Secret
   metadata:
     name: backup-secret
   data:
     restic-password: old
     restic-new-password: new
   

3. Scale backup-restore deployment up:
   kubectl -n taiga scale deployment backup-restore --replicas=1
4. exec into pod and execute restore pod
   kubectl -n taiga exec -it backup-restore -- change-password.bb
5. Scale backup-restore deployment down:
   kubectl -n taiga scale deployment backup-restore --replicas=0
6. Replace restic-password with restic-new-password in secret

   kind: Secret
   metadata:
     name: backup-secret
   data:
     restic-password: new
