BorgBackup is a deduplicating backup program with optional compression and encryption.
That means your daily incremental backups can be stored in a fraction of the space and is safe whether you store it at home or on a cloud service.
The backup will run based on `matrix_backup_borg_schedule` var (systemd timer calendar), default: 4am every day
You will need a remote server where borg will store the backups. There are hosted, borg compatible solutions available, such as [BorgBase](https://www.borgbase.com).
The backup will run based on `matrix_backup_borg_schedule` var (systemd timer calendar), default: 4am every day.
## Prerequisites
1. Create ssh key on any machine:
1. Create a new SSH key:
```bash
ssh-keygen -t ed25519 -N '' -f matrix-borg-backup -C matrix
```
2. Add public part of that ssh key to your borg provider / server:
This can be done on any machine and you don't need to place the key in the `.ssh` folder. It will be added to the Ansible config later.
2. Add the **public** part of this SSH key (the `matrix-borg-backup.pub` file) to your borg provider/server:
If you plan to use a hosted solution, follow their instructions. If you have your own server, copy the key over:
```bash

Check the `roles/matrix-backup-borg/defaults/main.yml` for the full list of available options
`matrix_backup_borg_location_source_directories` defines the list of directories to back up: it's set to `{{ matrix_base_data_path }}` by default, which is the base directory for every service's data, such as Synapse, Postgres and the bridges. You might want to exclude certain directories or file patterns from the backup using the `matrix_backup_borg_location_exclude_patterns` variable.
Check the `roles/matrix-backup-borg/defaults/main.yml` file for the full list of available options.
