This guide is part of the BackupYourSystem Page. It is separate for the sake of organization.

Introduction

Data can be lost in many different ways. Sometimes it is lost because of hardware failures, accidental deletion, or overwriting files. Some data loss occurs as a result of natural disasters and other circumstances beyond your control. Now we will use an easy backup and restore tool called Simple Backup Suite, or sbackup for short. SBackup is a simple backup solution intended for desktop use. It can backup any subset of files and directories. Exclusions can be defined by regular expressions. A maximum individual file size limit can be defined. Backups may be saved to any local and remote directories that are supported by gnome-vfs. There is a Gnome GUI interface for configuration and restore. SBackup uses compressed archives, so it is not the best backup solution if you are primarily backing up large amounts of multimedia like videos, photographs, or music. These data types are already compressed, so you will spend lots and lots of time compressing these files with gzip with little or no space being saved.

Installation

To install sbackup, you need to install the sbackup package from the Universe Repository. You can use Synaptic, or install from terminal:

sudo apt-get install sbackup

Backing Up Your Data

Once you have completed the installation you can access sbackup using System -> Administration —> Simple Backup Config, you can see this in the following screen {{https://help.ubuntu.com/community/BackupYourSystem/SimpleBackupSuite?action=AttachFile&do=get&target=1.png%7D%7D <

Recommended Backup

If you are new Ubuntu user or are not sure what you should backup. This will perform a daily backup of your /home, system data held in /etc, /usr/local and /var. This will deliberately exclude any files over 100MB. By default this backup will be stored in /var/backup.

Custom Backup

This is the same as the recommended backup and in this you can change the settings include, exclude files, you can change the schedule time. With this option you will be able to specify where to save the backup file.

Manual Backup

If you want to backup some files from time to time this option is for you. You can click backup now button to manually perform a backup according to the settings on the other backup properties dialog box tabs. With this option you will be able to specify where to save the backup file. For the rest of the guide, it will be assumed that you chose the custom backup or the manual backup option. If you chose the recommended backup, you will not be able to customize any settings. Next, click on the Include tab. Here you can include any file or directory you want to backup. {{https://help.ubuntu.com/community/BackupYourSystem/SimpleBackupSuite?action=AttachFile&do=get&target=4.png%7D%7D <

Restore Your Data

If you want to restore backups or any files or folders go to System —> Administration —> Simple Backup Restore, as shown in the following screen. {{https://help.ubuntu.com/community/BackupYourSystem/SimpleBackupSuite?action=AttachFile&do=get&target=13.png%7D%7D <

> In this example I have choose to restore one .iso file and once you select your file and click on Restore it will ask for your confirmation. Click on yes, this will restore the file in its original location. If you want to restore in a different location you need to select the Restore As option. {{https://help.ubuntu.com/community/BackupYourSystem/SimpleBackupSuite?action=AttachFile&do=get&target=15.png%7D%7D <
> Note: By default, Restored Files and Directories are owned by root This is because sbackup runs with root priveleges. You need to change these file or folder permissions using chmod, or just right click and select properties of the file or folder.

Backup Destination on Remote machine

One more nice thing about sbackup is that you can store your backup on a remote machine. For this it will give the option of using SSH or FTP. For this go to System —> Administration —> Simple Backup Config Once it opens the application you need to click on destination tab. Here you can select the Use a remote Directory option, type ssh:// or ftp:// followed by the username:password, then @, then the remote host to connect to and the remote directory. {{https://help.ubuntu.com/community/BackupYourSystem/SimpleBackupSuite?action=AttachFile&do=get&target=16.png%7D%7D <
> Final Tip: Sbackup does not create a new backup file each time it runs, instead it creates an incremental backup. This means that it updates the last backup with files which have been modified or created. Any files that have not been modified since the last backup are unchanged.

Sbackup Configuration from the command line

If you want to configure sbackup you need to edit the /etc/sbackup.conf file. Restore Backup from command line Run

sudo srestore.py /var/backup/2006-11-18_03 /home/myuser /home/myuser/old

You can omit the last parameter to restore to the same directory.

Automatically backup at shutdown

In case you want to shutdown your workstation when you're done and not have to backup manually every now-and-then, you might find it useful to have simple-backup being run every time you log off. To enable this, you need to do only a few things:

1. save this page UbuntuHelp:sbackupd to `?action=AttachFile&do=get&target=etc%2Finitd%2F%60
2. set file ownership to `root:root` and file permissions to: `rwx-r-xr-x`
3. execute the following from a terminal:

   sudo update-rc.d sbackupd start 00 0 1 6 .
   

   which will effectively run the downloaded script every time Ubuntu comes into single-user-mode, shutdown or reboot. Since the script will only run `sbackupd`, this effectively gives you a backup every time you shutdown or reboot your machine.
   

I find it useful to use both a schedule and this 'at-shutdown' script because i get a backup at least once a day, and i needn't care about keeping my machine powered on.

sudo update-rc.d -f sbackupd remove
