To backup your file in Ubuntu simply means making copy of your file and storing them somewhere for safekeeping. In the event you lose the original file on the computer, you can go to restore the file from the backup location.
Backing up is simply done in case the original files become unstable due to loss or corruption. You should store backup copies of your files somewhere separate from your computer — on an external hard disk, for example. A good location to store backup file is on a USB drive, external hard drive, CD/DVD or an online storage.
This brief tutorial show students and new users how to backup your important files on Ubuntu 17.10
How to Back up your Files
The easiest way of backing up your files and settings is to let a backup application manage the backup process for you. A number of different backup applications are available, for example Déjà Dup.
Alternatively, you can manually copy the file to a backup location instead of using an application. However, using an application to automatically backup your important files is the best method.
What to backup?
Your priority should be to backup important files as well as those that would be difficult to replace. Your personal files like documents, emails, financial documents, family photos and others that would be irreplaceable.
Other less important data would be your profile settings, installed software and system settings. These you can replace, but might spent sometime on settings back to the way there were.
Ubuntu default backup application is called Deja Dup. To access the backup program, click Activities from the top left menu and on the Activities Overview, search for Backups.
Open Backup from the activities overview and launch Deja Dup.
Turn on backups by moving the button to the right to show ON. Then select the Folders to save. This is the folders and files to backup. By default, it should backup your entire home directory. You can also add more location to backup. For most individuals, this is enough.
Select the Storage location.. this is where the backup copies will be store. It can be a local disk, but not recommended. You select local folder and browse to the USB drive or external hard drive to back up.
If you have Nextcloud online account, select that and sign to automatically backup your data online.
Finally, select the Scheduling page. This is where you schedule how often to backup your file and how long to keep copies of the files.
When you’re done, save and exit.
