Hey friend!
This situation is a bit deeper than anyone can know from an external perspective. If you have a system administrator that you trust, you should ask them to review that server for you. Files don’t really just go missing from a reboot, and it’s especially odd if they do and yet the operating system still boots (as that kind of file system corruption is unlikely to specifically target items non-essential to boot).
My concern is that your server was compromised and configured by an attacker to act this way. Most likely you’re not going to restore that data in a meaningful way and should start pulling your external backups. I would not re-deploy on this server, but I would have a sysadmin look at it to see if any evidence remains of what occurred so that it might be prevented.

It’s worth double-checking if you have backups enabled:
- DigitalOcean Snapshots:
- Log in to your DigitalOcean Control Panel.
- Navigate to the “Droplets” section.
- Check if there are any snapshots that were taken automatically or manually. If you find one, you can create a new droplet from the snapshot to recover your files.
- Backups:
- Again, check if you might have enabled backups at any point. These are different from snapshots and might provide another route to recovery.
If snapshots and backups are not available, you can try using testdisk to recover deleted files. testdisk is a powerful data recovery tool that can work in some cloud environments. You can also check this article:
