NAME
config - 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 useable with
backintime-qt4. 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.
