.Nm evobackup-incl
.Nd incremental backup configuration
.Sh SYNOPSIS
.D1 +%Y-%m-%d.-%day
.Sh DESCRIPTION
Located by default in
.Pa /etc/evobackup/ ,
each
.Nm
file is named after the
.Xr bkctld 8
backup for which the rules it contains must apply.
.Pp
The rules it defines decide which incremental backups are kept when running
.Bd -literal -offset indent
# bkctld rm
.Ed
.Pp
Each line defines a single rule.
The first part of the rule describes when the backup was taken,
the second part decides how long to keep it.
Lines beginning with the
.Sq #
character are comments and are ignored.
The order of the rules does not matter.
.Pp
Evobackups that do not have their nominal
.Nm
file use the default rules defined in
.Pa /usr/share/bkctld/inc.tpl
