Backups should also be incremental when possible (rather than mirror copies) so an accidental deletion isn't propagated into the backups, making the file irrecoverable.
## Strategy
The key is to have one central location that all your files, projects, and data are cloned to and then back that directory up to multiple locations.
I have one backup folder `/mnt/backup` on my media server at home that serves as the destination for all my backup sources. All scheduled automatic backups write to their own subfolder inside of it.
This backup folder is then synced to encrypted 2.5" 1 TB hard drives which I rotate between my bag, offsite, and my parents' house.

## Backup Sources
I use the tool `rdiff-backup` extensively because it allows me to take incremental backups locally or over SSH. It acts very similar to `rsync` and has no configuration.

The virtual server has routing enabled and forwards inbound traffic __from the internet__ to my media server at home. This allows me to have external HTTP and SSH access.

## Server Setup
Spin up a Debian 12 server on your favourite hosting provider. If you're using an older version of Debian, you can follow the [[Bypassing Ports Old |old version of this article]]. You should harden this server. Assign a subdomain to it like `vpn.example.com`.
