Ubuntu Tip Simple Backup Command Using CP

Backing up your computers hard drive is extremely important. Should the worst happen and you lose all of your important data, you need a way back. While there are many excellent utilities in the Ubuntu repositories that handle partial and full system backups. Sometimes a simpler solution is all that is needed.

Fortunately Ubuntu and Linux in general in fact comes with everything you need in the for of the very simple but also extremely powerful cp command. In case you havent figured it out yet, cp is Linux command line speak for copy. The examples below will show you how to use cp to back up your entire system.

sudo cp -r -u -x -v [source directory] [destination directory]

Example 1:
sudo cp -r -u -x -v /home/ /media/MY_USB_DRIVE

sudo: Gives temporary root privileges.

cp: Linux command line copy command.

-r: Used with cp this switch causes cp to copy directory content recursively. Meaning it will copy all files and subdirectories in the directory being copied.

-u: Used with cp this switch causes cp to only copy files that have changed or dont already exist at the destination.

-x: Used with cp this switch stops cp jumping to other file systems which it will do if it encounters hard links or symbolic links.

This switch also stops cp eating its tail if you choose to back up your entire system. See examples 2 and 3 below.

-v: Used with cp this switch cause cp to give feed back on whats happening.

Full System Backup With CP
If we wish to perform a full system backup then we might feel inclined to use a command similar to that in Example 2 below. The trouble is without the -x switch cp will also attempt to backup the backup to the backup. Basically eating its own tail in a never ending loop until all disk space is used up.

This happens because all other file systems are mounted to a location branching from the root file system. So if root is / then home is mounted to /home. Within Ubuntu all USB drives tend to be mounted to /media/a_USB_drive, etc.

However with the -x switch the command in example 2 will not be enough to back up the entire system if there are several storage devices or file systems mounted to different mount points. To get around this problem we must write a small script that will backup each file system separately. Example 3 shows a small example where the root files system / and /home are backed up separately.

Example 2:
sudo cp -r -u -v / /media/MY_USB_DRIVE

Example 3:
#!/bin/sh
#
# cp based backup script.
#
sudo cp -r -u -x -v / /media/MY_USB_DRIVE
sudo cp -r -u -x -v /home/ /media/MY_USB_DRIVE

This script can be created in any text editor like gedit or nano. After the script has been saved it must be given permission to be run as a program. Example 4 shows the command needed to change to the directory/folder where the script is stored. How to apply execute permissions and how to run the script.

Example 4:
First open a terminal window if you havent already done so and enter the following commands. The actual location of your script is where you chose to save it.

cd /home/aikiwolfie/scripts/ (press enter)
chmod a+x my_backup_script (press enter)
./my_backup_script (press enter)

And thats it. Sit back and watch the backup script do its job.

Ubuntu auto backup to remote host using scp rsync crontab

Bash script to transfer files via SCP

#!/bin/bash 
REMOTE_IP="x.x.x.x"
SCP_PASSWORD="mypassword"
expect -c " 
 set timeout 1
 spawn scp -r /Local/SourceFolder uname@$REMOTE_IP:/Remote/DestFolder
 expect yes/no { send yes ; exp_continue }
 expect password: { send $SCP_PASSWORD }
 expect 100%
 sleep 1
 exit
" 

Save the above script to autoscp.sh and give the execute permission. The SourceFolder is the folder whose contents are sent to DestFolder on the remote host .

$ chmod +x file.sh
$ ./file.sh

Install expect if its not on our machine, expect  is a program that "talks" to other interactive programs according to a script. We use this in this script to provide the password when asked for by the scp command.

sudo apt-get install expect

Bash script to sync local & remote folder via rsync

#!/bin/bash 
REMOTE_IP="x.x.x.x"
SCP_PASSWORD="mypassword"
#And now transfer the file over
expect -c " 
 set timeout 1
 spawn rsync -azvv -e ssh /Local/SrcFolder uname@$REMOTE_IP:/Remote/DstFolder
 expect yes/no { send yes ; exp_continue }
 expect password: { send $SCP_PASSWORD }
 expect 100%
 sleep 1
 exit
" 

-a preserves the date and times, and permissions of the files
-z compresses the data
-vv increases the verbosity of the reporting process
-e specifies remote shell to use

Save the above script to autorsync.sh file and give the execute permission.

Scheduling this rsync and scp scripts to run periodically

Use crontab to schedule these scripts to run periodically. To edit crontab use

crontab -e

Add the below lines

# m h dom mon dow command
0 * * * * cd /location/of/script;./autoscp.sh
30 * * * * cd /location/of/script;./autorsync.sh

m - minute
h - hour
dom - day of the month
mon - month
dow - day of the week
0 * * * *  will run the script at 0 minutes every hour, every day of all the months.
30 * * * * will run the script at every 30 minutes on every hour, every day of all the months.
