# Home Assistant backups: keep the emergency kit, store copies off the device

> Home Assistant backups are always encrypted; without the encryption key from the backup emergency kit you cannot restore them. Schedule automatic backups, keep copies outside Home Assistant and one off-site, and test a restore.

## The one thing people lose

Home Assistant backups are **always encrypted**. To restore one you need the **encryption key from the backup emergency kit**. When you set up backups, download the emergency kit and store it somewhere safe *outside* Home Assistant (password manager, printed copy). A backup without the key is useless, and the key stored only on the dead device is too.

## What a backup contains

A full backup includes `config`, `share`, `addons` (only apps you installed or created manually; store apps are reinstalled), `ssl` and `media`. A partial backup is any subset of these.

By default backups are compressed `.tar` files in the local `/backup` directory, on the same disk as everything else.

## Setup

1. **Settings → System → Backups**: configure **automatic backups** (schedule, time, how many to keep).
2. Enable **backup before updating** as the default. On large installs the backup can delay the update start.
3. Add **at least one location outside the device**: network storage (NAS) or a cloud provider. Home Assistant recommends a copy outside Home Assistant and ideally one **off-site**.
   - Home Assistant Cloud keeps **one** backup file of up to **5 GB**: the latest one.
4. Exclude what you don't need (big media folders, large databases) if backups get too large.

## Restore and migration

- On a fresh install, choose **restore from backup** during onboarding and upload the file plus the key.
- The same path migrates to new hardware, e.g. from a Raspberry Pi to a mini PC. The target needs enough storage.

## Test it

A backup strategy you haven't restored is a guess. Restore to a VM or spare device once, with the emergency kit, before you need it.

## Claims

- Home Assistant Cloud stores one backup file of up to 5 GB: the backup that was saved last. (unverified)
- By default, Home Assistant stores backups as compressed .tar archives in the local /backup directory. (unverified)
- A Home Assistant backup can be restored during onboarding, which is also how an installation is migrated to another device. (unverified)
- Home Assistant backups are always encrypted, and restoring them requires the encryption key stored in the backup emergency kit. (unverified)
- A full Home Assistant backup includes the config, share, addons (only manually installed or created apps), ssl and media directories. (unverified)
