backintime-config - Man Page

BackInTime configuration files.

Synopsis

~/.config/backintime/config
/etc/backintime/config

Description

Back In Time was developed as pure GUI program and so most functions are only usable with backintime-qt. But it is possible to use Back In Time e.g. on a headless server. You have to create the configuration file (~/.config/backintime/config) manually. Look inside /usr/share/doc/backintime-common/examples/ for examples.

The configuration file has the following format:
keyword=arguments

Arguments don't need to be quoted. All characters are allowed except '='.

Run 'backintime check-config' to verify the configfile, create the snapshot folder and crontab entries.
