How to back up MAAS

MAAS uses standard command-line utilities for simple, familiar backups.

Clean reset backup

Uses pg_dumpall. Fully overwrites MAAS and PostgreSQL on restore.

Backup

1. Find PostgreSQL service:

   sudo systemctl list-units --type=service | grep postgres
   

2. Create backup directory:

   mkdir -p <backup-path>/$(date +%s)
   

3. Dump database:

   sudo -u postgres pg_dumpall -c > "<backup-path>/$(date +%s)_dump.sql"
   

4. Stop MAAS:

   sudo snap stop maas
   

5. (Optional) Stop PostgreSQL:

   sudo systemctl stop postgresql.service
   

6. Snap backup:

   sudo snap save maas
   

7. Export snapshot:

   sudo snap export-snapshot <snapshot-id> <backup-path>/$(date +%s)_snapshot
   

8. Restart services:

   sudo systemctl start postgresql.service
   sudo snap restart maas
   

Restore

1. Stop MAAS & remove instance:

   sudo snap stop maas && sudo snap remove maas
   

2. Restore database:

   sudo -u postgres psql -f <backup-path>/<dump.sql> postgres
   

3. Import & restore snapshot:

   sudo snap import-snapshot <backup-path>/<snapshot>
   sudo snap restore <snapshot-id>
   

4. Restart services:

   sudo systemctl start postgresql.service
   sudo snap restart maas
   

Clean package backup

Backs up PostgreSQL and key MAAS files.

Backup

1. Find PostgreSQL service:

   sudo systemctl list-units --type=service | grep postgres
   

2. Create backup directory:

   mkdir -p <backup-path>/$(date +%s)
   

3. Dump database:

   sudo -u postgres pg_dumpall -c > "<backup-path>/$(date +%s)_dump.sql"
   

4. Stop MAAS services:

   sudo systemctl stop maas-dhcpd.service maas-rackd.service maas-regiond.service
   

5. (Optional) Stop PostgreSQL:

   sudo systemctl stop postgresql.service
   

6. Archive MAAS files:

   sudo tar cvpzWf <backup-path>/$(date +%s)_maas_backup.tgz --exclude=/var/lib/maas/boot-resources /etc/maas /var/lib/maas
   

7. Restart services:

   sudo systemctl start postgresql.service
   sudo snap restart maas
   

Restore

1. Reinstall Ubuntu (if possible).
2. Ensure PostgreSQL is installed.
3. Restore database:

   sudo -u postgres psql -f <backup-path>/<dump.sql> postgres
   

4. Install MAAS from packages.
5. Stop MAAS services:

   sudo systemctl stop maas-dhcpd.service maas-rackd.service maas-regiond.service
   

6. Extract backup:

   sudo tar xvzpf <backup-path>/<backup.tgz> -C /
   

7. Restart services:

   sudo systemctl start postgresql.service
   sudo systemctl restart maas-dhcpd.service maas-rackd.service maas-regiond.service
