Intro

backintime enables incremental backup of files.

Listing it as the first application software to be installed after installing Ubuntu is an indication of the importance of backing up files.

-> Top

Install

Execute:

$ sudo apt install backintime*
$ sudo apt install backintime-qt

(updated 12 May 2020)

-> Top

Bring up

Select Activities.

Type "ba" to bring up some application icons:

Select Back in Time (root) to show the front page:

Alternatively, execute

$ sudo i backintime
or
$ pkexec backintime

However, the terminal commands are not reliable to bring up backintime. Using the graphical desktop is more reliable.

Take snapshot any time

Bring up the front page:

Select the take snapshot button: 

It would take some time to take a snapshot depending on the extent of file changes since the last snapshot.

-> Top

Restore

Restore backup files when the present files have been lost or corrupted.

Bring up the front page:

 

Select:

• the desired snapshot in the left window
• the desired backup folder in the middle window
• one or more folders or files in the right window

Select the restore button:

Select whether to backup local files with a trailing suffix before restoring the old files:

Select Yes to proceed if for sure.

Folders and files will be restored.

It would take some time depending on the size to be restored.

Let the process finish with the use permissions set back to the original state.

If only the folders in the middle window is selected before the restore button is selected, this message will appear to indicate that the "/" root folder will be restored:

It is important not to just select the folders in the middle window and select the restore button to proceed, because it will easily restore files to the "/" root directory and overwrite the still valid system and programme files in the root directory to cause problems.

Repair

Sometimes, backintime cannot be brought up to run, even after a removal and re-installation.

This can be caused by the removal of some other programmes which backintime depends on but which have been removed when some other application software is removed. Re-installation of backintime may not bring them back.

The following shows the programmes which backintime depends on:

Try to re-install the missing programmes:

$ sudo apt install <name of programme>

rsync, python3, openssh-client are likely missing programmes.

 

In case of the following error:

Traceback (most recent call last):
  File "/usr/share/backintime/common/backintime.py", line 28, in <module>
    import config
  File "/usr/share/backintime/common/config.py", line 45, in <module>
    import tools
  File "/usr/share/backintime/common/tools.py", line 37, in <module>
    from packaging.version import Version
ModuleNotFoundError: No module named 'packaging'

 

Execute:

$ sudo apt install python3-packaging
