Questions: How can I backup and restore Ubuntu?, How to backup and restore Debian?, How to backup and restore Linux Mint using Timeshift?. Are you looking for a way to create system snapshots on Ubuntu, Debian, and Linux Mint Linux distribution?. Snapshots allow you to restore your entire operating system to a point in time state. This comes in handy whene you experience system failure or sluggish behavior.
In this blog post, I’ll show you how you can easily create system snapshots on Ubuntu, Linux Mint and Debian Linux system using Timeshift.
What is Timeshift?
Timeshift is an open source tool for creating filesystem snapshots using rsync+hardlinks or BTRFS snapshots. It has support for scheduled snapshots, multiple backup levels, and exclude filters. Once you have a snapshot taken, it can be restored while the system is in a running state or from Live CD/USB.
Install Timeshift on Ubuntu / Debian / Linux Mint
Now that you have some basics about Timeshift, let’s change gear to the installation bit. We’re going to install Timeshift on Ubuntu / Debian from the official OS repositories.
sudo apt update
sudo apt install -y timeshiftCreate System Snapshots using Timeshift
You’ll need to save your snapshots in a separate partition. So before I can start Timeshift application, I’ll configure disk and partition used for saving Snapshots. I have a secondary disk /dev/sdb on my machine.
# lsblk
sdb 8:16 0 10G 0 disk
I’ll create a partition table and filesystem on this block device.
$ sudo parted /dev/sdX mklabel gpt
$ sudo parted /dev/sdX mkpart primary 0% 100%
$ sudo mkfs.ext4 /dev/sdX1

Allocating group tables: done
Writing inode tables: done
Creating journal (16384 blocks): done
Writing superblocks and filesystem accounting information: done
Once done, Launch Timeshift from terminal or Applications search menu.
Provide sudo password when prompted.
Select Snapshot type.
Select location where snapshots should be saved.
Select Snapshot Levels
You can choose to use your desired backup options that you see fit for your use case.
eate the first Snapshot manually by clicking on the “Create” button at the top menu.
Restoring System from Snapshot using Timeshift
To revert your system to Snapshot state, select the Snapshot you want to restore to and click the “Restore” tab on the top menu.
This will ask you to “Select target device” and options for /boot and /home.
Timeshift will Perform Dry run before doing the actual restore.
Confirm Actions to initiate Snapshot restore process.
Timeshift will start to sync Snapshot files to the root filesystem.
The system should reboot after the process is completed.
