Fedora 5 Backup to usb hard drive

Hello EE.  I have a linux box, providing file services, firewall and proxy.  setup with help from many of you (thanks)
What I want to do is backup the /data partition (samba)  to a usb drive which is permanently attached and then shut down the machine daily at 7pm.  So basically I have a folder on the driver  which is at /media/sea_disk/Backups

I would like the daily backup to only backup what has changed.  And then on saturday do a complete backup to the same location.

And then shut down the machine.

for the daily backup, you can try rsync

rsync -avz --delete /data/* /media/sea_disk/Backups/

please note that the --delete is only an option if you want the target files to be deleted as well. remove it if you want to retrieve any deleted files that a user might request for (which happens at all time with me :-)

for a weekly backup, just to a

cp -Rp /data/* /media/sea_disk/Backups/  

the weekly backup and daily backup can be run through the crontab.

do a

crontab -e (as root)

01 0 * * * (your rsync command here)

and for weekly backup

01 0 * * 6 (your cp command here)

the weekly would run on mondays at the change of system clock date.   the hour can be any 24 hour format to run at a specified time.

by shutdown the machine are you stating that the machine should be powered off??? or only the usb drive to unmounted???

you can also put the same in a bash script and run it as a script at an appointed hour ending with

'shutdown -h -t 5 "an optional message here"   ' (without the initial and end single quote) at the end of the script to tell the machine to shutdown after finishing the rsync/ cp command.

sorry the weekly command is to run on saturdays (number 6 in crontab entry is right) but monday is wrong

ygouthamCommented:
in crontab you have five fields

01 13 * * * sh /path/to/some/script.sh

the above line means to execute a script called script.sh which is a shell script at 13:01 hours every day.  read more on

man 5 crontab
man crontab

to shutdown a machine

shutdown -h -t 5 now

this means to shutdown the machine in 5 seconds from now and halt the system.  the same command can also go into your crontab.  but shutdown is not given enough rights to be run from crontab.  just check on the first before adding the same.  just look at /etc/sudoer
