| − | == Common setup ==
| |
| − | | |
| − | A pub/private keypair; with a blind, incremental rsync over ssh.

| − | It relies on
| |
| − | | |
| − | .ssh/config
| |
| − | .ssh/id_rsa
| |

| |
| − | | |
| − | which does an incremental backup (rsync) of all mounted EXT4 volumes - excluding the devices:

| − | with a quick sentinel and we're keeping a log of the most recent backups. In order for the email to work - outbound ssmtpd was configured in /etc/ssmtp/ssmtpd.conf as:
| |
| − | | |
| − | FromLineOverride=YES
| |
| − | mailhub=smtp.xs4all.nl

| |
| − | | |
| − | backed by an encrypted FS with a daily zfs-snapshot post the backup run; which ultimately gets offloaded onto tape. The rentention policy is currently 5 years (to be adjusted).
