For security reasons you should chmod /var/backup and the backup file. Users could copy the backup over and untar it and have a nice readable shadow file. |

| anyone else for making such a script part of the base install or the gentoolkit package? I mean it wouldn't be "Active" until the user does an rc-update to add it to the ini anyway....so why not make a standard tool for backup the ever so important /etc directory? |

Here is my contribution:
1.- Don't show any message such 'file not found' when run for the first time (as first make the tar.bz and then check for files)
2.- Added hour-minute-and-second to the tar name so we can run at any time (with /etc/init.d/backup-etc restart) and still stores the three last tar.bz's
| Code: |
#!/sbin/runscript
# Backs up /etc/*
# Put this script in /etc/init.d and perform the following:
# chmod 0755 /etc/init.d/backup-etc
# rc-update add backup-etc default
start() {
local BACKUPDIR="/var/backup"
local DATE=`date +%Y%m%d-%H%M%S`
ebegin "Backing up /etc/* to ${BACKUPDIR}/etc-${DATE}.tar.gz"
if [ ! -d ${BACKUPDIR} ]
then
mkdir -p ${BACKUPDIR}
chmod 700 ${BACKUPDIR}
fi
tar -Pzcspf ${BACKUPDIR}/etc-${DATE}.tar.gz /etc
local files=`ls -r ${BACKUPDIR}/etc*.tar.gz`
backup=3
for arg in ${files}
do
if [ "${backup}" -le 0 ]
then
rm -f ${arg}
else
backup=$((${backup} -1))
fi
done
chmod 700 ${BACKUPDIR}/etc-${DATE}.tar.gz
eend $?
}

how about changing
chmod 700 ${BACKUPDIR}/etc-${DATE}.tar.gz
to
chmod 600 ${BACKUPDIR}/etc-${DATE}.tar.gz
no need to make it have executable permissions  |
