Automatically backup installed FreeBSD packages

Thursday, January 19, 2006

A while ago I threw together this script to automatically create package files for all installed ports on a FreeBSD box. That way, if a portupgrade doesn't work out, you can delete the broken package, and pkg_add the backup.

Stick this in /usr/local/etc/periodic/daily, and the system will automatically bundle up copies of the installed software and stick them in /usr/local/packages if they don't already exist in there.

#!/bin/sh

# Make sure backups exist of all installed FreeBSD packages

ARCHIVE="/usr/local/packages"

#
# Figure out which pkg_tools binaries to use
#
if [ -f /usr/local/sbin/pkg_info ]
then
    PKG_TOOLS="/usr/local/sbin"
else
    PKG_TOOLS="/usr/sbin"
fi

#
# Make sure backup directory exists
#
if [ ! -d $ARCHIVE ]
then
    mkdir $ARCHIVE
fi

cd $ARCHIVE

for p in `${PKG_TOOLS}/pkg_info -E "*"`
do
    if [ ! -f ${p}.tgz ]
    then
        ${PKG_TOOLS}/pkg_create -b ${p}
    fi
done
