Revision of Backup Files Quickly and Easily from Sat, 03/23/2024 - 05:33

This documentations shows how to backup files, in our case the home directory, to a mounted drive. We will cover this topic with the applications Back in Time, that can be used graphically and on the command line and later rsync, a command line tool.

Back in Time and rsync are pre-installed on Trisquel GNU/Linux. For instructions on how to install them, see the Documentation about Installing, Updating and Removing Software.

• To select /home/<user name> folder to backup, in Settings go to the tab titled Include, click Add folder and select the folder <user name>

Now, /home/<user name> should be listed in Include files and folders

You're done!

Using Back in Time from the command line

To back up:

 backintime backup

To list options run:

 backintime -h

Comment

This is the simplest way to backup and restore. Please take a look at other options e.g. Mode, Schedule, et cetera.

Using rsync

To make a backup of your home directory using rsync you can use the following example:

First, create a directory on a mounted drive. For example, run the following command in a terminal, where /media/trisquel/backup/home/$USER/ is the target we want to use later:

 mkdir -p /media/trisquel/backup/home/$USER/

Second, run rsync, where /home/$USER/ is the source and /media/trisquel/backup/home/$USER/ is the target. Make sure not to forget the / at the end of them, that will mark them as a directory. The following command will exclude the .cache directory, because in most cases it is not needed.

 rsync -av --exclude=.cache /home/$USER/ /media/trisquel/backup/home/$USER/

To restore a backup you can use rsync again.

 rsync -av /media/trisquel/backup/home/$USER/ /home/$USER/

Adapt this examples to your needs!

Notes

For your security, you should only store your data on a device you control, e.g. an external drive.
