I’m in the process of moving to a new Droplet using this guide

> This method is different than restoring file in UI. Maybe there is a more downtime but it’s simpler for linux folks without Discourse knowledge and it’s easy to automate. Prepare new VPS First, prepare our new Current Ubuntu LTS VPS with empty Discourse dir, OS upgrade and Docker install sudo mkdir -p /var/discourse sudo apt-get update sudo apt-get dist-upgrade wget -qO- https://get.docker.com/ | sh Then, make sure that we are on latest installed kernel and other libraries by just restarting …

I’ve gotten to where I need to rebuild, and it goes along fine for a while before getting here:

```plaintext

2933:C 21 Dec 2023 17:29:25.583 * DB saved on disk

```

Looking at older posts which mention this issue, most of the suggestions center around rebooting your VPS and retrying the command. I did this and it did not resolve the problem. I have now run the rebuild three times with the following results:

1. Reboot without it returning
2. Waited about an hour and the following finally happened

```

1. Ran for about an hour before I got a broken pipe error and disconnected

Any clues as to how to proceed from here?

This droplet is 2G RAM / 50G disk running Ubuntu 23.10 x64. The rsync command seemed to run as expected.

Thank you!
