Backup incident troubleshooting guide

This guide walks you through the steps to identify and resolve backup issues reported via email. The goal is to help you fix the problem quickly, or gather the right info before reaching out to our support team.

Step 1: Spot services with errors​

  1. Log in to your Datashelter dashboard.
  2. Click on Servers, then select the server in question.
  3. You’ll see a list of your services, each showing the date of the last snapshot.
  4. If a service has no date, or the date looks outdated, it’s likely where the issue is.

Tip: Keeping an eye on snapshot dates helps catch problems early.

Step 2: Check the backup logs​

  • Backup logs are stored locally on your server at /tmp/snaper.

  • To see which backup name matches which path, run:

    snaper list files

    Example output:

    BACKUP NAME    PATH
    -----------    ----
    crimson-surf   /etc/nginx/sites-available
    summer-sea     /etc/letsencrypt
    damp-cloud     /var/www/blog
    spring-fog     /var/www/blog-fr
    purple-tree    /var/www/datashelter.tech
    ``

Step 3: Try a manual backup​

Once you’ve identified the service, you can re-run its backup manually using:

snaper backup <files/database> --name <servicename>

Example:

snaper backup files --name crimson-surf

If the backup completes successfully, you’re all set. If it fails again, move on to the next step.
