"i want to make a backup script to make incremental backup every day on the lastday backup.
can any one hlp me for that"
I use the cpbk in a cron job to do a daily incremental backup to a backup partition. Here is my script:
# This command saves fedora to a backup disk
# partition
# It only copies files that have changed.
# It removes backup files for which the source file has been deleted.
# If /backup does not exist then error touch and exit
if test ! -d /backup;
then
touch /root/data/backups/cpbk.failed.date
exit 1
fi
if test ! -d /backup/fedora;
then
mkdir /backup/fedora
fi

mkdir /backup/fedora/bin
