How often does a full backup happen, how can I configure this?

By default, a full backup will happen if the last full backup is older than 30 days. Between full backups, all backup sessions are incremental.

We recommend enabling the daily backup cron job so that daily incremental backups happen automatically:

chmod +x /etc/cron.daily/tklbam-backup

You can override the default by setting the full-backup parameter in the tklbam configuration:

# create a full backup every 14 days
echo full-backup 14D >> /etc/tklbam/conf
