Proxmox Backup and Restore

This guide provides options for consistently backing up a server, instructions for restoring from backups, and best practices for testing backups prior to needing them.

Back to Server_Guides

Assumptions

This guide focuses on Proxmox servers and assumes:

  • A directory is established on the server for backups. Example: `/datadrive/Backups/`
  • Services run within containers and VMs on the Proxmox server (host).
  • SSH keys have been established and copied into each VM and container. Refer to the SSH Keys guide for more on SSH key generation and usage.

For specific service guides, see:

Backup

# /usr/local/bin/proxmox-backup.sh

# Define variables
BACKUP_DIR="/datadrive/Backups"
VZ_DIR="/var/lib/vz/dump"
BACKUP_REMOTE="pcloud:Backups/Server-Backups"
VZ_REMOTE="pcloud:Backups/Server-Backups/VZDUMPS"
LOCAL_BACKUP_DIR="/datadrive/Backups"

# Authentik variables
AUTHENTIK_REMOTE_USER="root"
AUTHENTIK_REMOTE_HOST="192.168.4.134"
AUTHENTIK_REMOTE_BACKUP_DIR="/home/authentik/authentik/authentik_backups"
TIMESTAMP=$(date +"%Y%m%d%H%M%S")

# Ensure remote backup directory exists
ssh $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST "mkdir -p $AUTHENTIK_REMOTE_BACKUP_DIR"

# Backup PostgreSQL Database
ssh $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST "docker exec -i authentik-postgresql-1 /usr/local/bin/pg_dump --username authentik authentik > $AUTHENTIK_REMOTE_BACKUP_DIR/postgres-back"

# Save Redis Database
ssh $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST "docker exec -i authentik-redis-1 redis-cli save"

# Copy Redis Dump
ssh $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST "docker cp authentik-redis-1:/data/dump.rdb $AUTHENTIK_REMOTE_BACKUP_DIR/redis-backup-$TIMESTAMP.rdb"

# Create Tarball of Necessary Files
ssh $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST "tar czvf $AUTHENTIK_REMOTE_BACKUP_DIR/authentik-backup-$TIMESTAMP.tar.gz -C /home/authentik/authentik authentik docker-compose.yml certs"

# Sync from Authentik server to Proxmox backup
rsync -avz --progress $AUTHENTIK_REMOTE_USER@$AUTHENTIK_REMOTE_HOST:$AUTHENTIK_REMOTE_BACKUP_DIR $LOCAL_BACKUP_DIR/authentik_backups

echo "Remote backup completed successfully."

Restore

Instructions for restoring from backup will depend on the specific service and the type of backup used. Refer to the Authentik Backup or other service-specific guides for restoration steps.
