### Memory Setup

sudo dd if=/dev/zero of=/var/swappfile bs=1M count=1024

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1662832950239/N9kSRo-KC.png)

sudo chmod 600 /var/swappfile

sudo mkswap /var/swappfile

sudo echo "/var/swappfile none swap 0 0" | tee -a /etc/fstab

Or

sudo nano /etc/fstab

// add  
/var/swappfile none swap 0 0

swapon -a

free -m

services:  
  urbackup:  
    image: uroni/urbackup-server:latest  
    container_name: urbackup  
    restart: unless-stopped  
    environment:  
      - PUID=1000 # Enter the UID of the user who should own the files here
