TimeShift – Provides System Restore functionality in Ubuntu
Sponsored Link
Snapshots are taken using rsync and hard-links. Common files are shared between snapshots which saves disk space. Each snapshot is a full system backup that can be browsed with a file manager.
Features:
Minimal Setup
TimeShift requires very little setup. Just install it, run it for the first time and take the first snapshot. A cron job will be enabled for taking automatic snapshots of the system at regular intervals. The backup levels can be selected from the Settings dialog.
Snapshots are saved by default on the system (root) partition in path /timeshift. Other linux partitions can also be selected.
Boot Snapshots
Boot snapshots provide an additional level of backup and are taken 30 minutes after the system is started.
Hourly, daily, weekly and monthly levels can be enabled if required.
Better Snapshots and Rotation
TimeShift runs at regular 30-minute intervals but takes snapshots only when needed.
Applications like rsnapshot rotate a snapshot to the next level by creating a hard-linked copy. Creating a hard-linked copy may seem like a good idea but it is still a waste of disk space. This is because only files can be hard-linked and not directories. The duplicated directory structure can take up as much as 100 MB of space. TimeShift avoids this wastage by using tags for maintaining backup levels. Each snapshot will have only one copy on disk and is tagged as "daily", "monthly", etc. The snapshot location will have a set of folders for each backup level ("Monthly", "Daily", etc) with symbolic links pointing to the actual snapshots tagged with the level.
System Restore
Snapshots can be restored either from the running system or from a live CD. Restoring backups from the running system requires a reboot to complete the restore process.
Cross-Distribution Restore
You can also TimeShift across distributions. Let's say you are currently using Xubuntu and decide to try out Linux Mint. You install Linux Mint on your system and try it out for a week before deciding to go back to Xubuntu. Using TimeShift you can simply restore the last week's snapshot to get your Xubuntu system back. TimeShift will take care of things like reinstalling the bootloader and other details. Since installing a new linux distribution also formats your root partition you need to save your snapshots on a separate linux partition for this to work.
Excluded Files
TimeShift is designed to protect system files and settings. User data such as documents, pictures and music are excluded by default. This has two advantages:
You don't need to worry about your documents getting overwritten when you restore a previous snapshot.
Your music and video collection will not waste space on the backup device.
Install timeshift in ubuntu 13.10/13.04/12.10

sudo aptitude update
sudo aptitude install timeshift
Screenshots
Well, i installed timeshift and it showed me that first snapshoot need 8,1GB. I have 25GB free space on my HDD where i planned to store snapshots. I clicked Backup and it filled up whole 25GB until i had 0 bytes free space. What’s up with that? I removed timeshift and deleted timeshift snapshot folder.
I’d really like to use timeshift, but it modifies my crontab entries — such that all entries are deleted, only timeshift’s own remaining.
How to stop this unwanted behaviour?
THANKS for consideration!
How can i change the save directory “/timeshift” ?
Timeshift cannot be installed on 14.04 LTS, is that correct?
sudo aptitude update
sudo aptitude install timeshift
Both the message “command not found”
Timeshift is not a part of the Ubuntu Repository so your method won’t work. Use the following to install:
sudo add-apt-repository ppa:teejee2008/ppa
$ sudo apt-get update
$ sudo apt-get install timeshift
In 14.04 I get a “cannot add ppa” message. Any suggestions?

On Mythbuntu 12.04, Timeshift does not allow me to save on an external hard drive. The drive shows up in the list of storage devices, but the mounted drive is not selectable.
Correction: (Mythbuntu 14.04, not 12.04. ) Timeshift does allow external drives, and they must contain a Linux partition. When I posted before, my external drive had a NTFS partition. I formatted it to Linux and it works fine with Timeshift.
I have external drive with ext4 partitioning and timeshift doesn’t allow me to select that drive.
