Modify the Borgmatic configuration `/etc/borgmatic/config.yaml`:
|
|
|
|
```
|
|
|
|
location:
|
|
|
|
source_directories:
|
|
|
|
- /etc
|
|
|
|
- /home
|
|
|
|
- /opt
|
|
|
|
- /root
|
|
|
|
- /srv
|
|
|
|
- /usr
|
|
|
|
- /var
|
|
|
|
|
|
|
|
repositories:
|
|
|
|
- backuplogin@backupmachine:/path/to/backup/Borg.repo
|
|
|
|
|
|
|
|
exclude_from:
|
|
|
|
- /etc/borgmatic/excludes
|
|
|
|
|
|
|
|
storage:
|
|
|
|
ssh_command: ssh -p XXXXX
|
|
|
|
# archive_name_format: '{fqdn}-{now:%Y-%m-%dT%H:%M}'
|
|
|
|
archive_name_format: '{fqdn}-{now:%Y%m%d}'
|
|
|
|
|
|
|
|
retention:
|
|
|
|
prefix: '{fqdn}-'
|
|
|
|
|
|
|
|
output:
|
|
|
|

|
|
|
|
|
|
|
|
```
|
|
|

Check the Borgmatic configuration file:
|
|
|
|
```
|
|
|
|
validate-borgmatic-config
|
|
|
|
```
|
|
|
|
|
|
|
|
Define the borgbackup machine in `/etc/hosts`:
|
|

```
|
|
|
|
xxx.xxx.xxx.xxx backupmachine
|
|
|
|
```
|
|
|
|
|
|
|
|
Create local SSH keys:

Sometimes, there is broken pipe with ssh. Add the following to the `~/.ssh/config` file on the client:
|
|
|
|
```
|
|
|
|
Host *
|
|
|
|
ServerAliveInterval 120
|
|
|
|
```
