WARNING: TimeVault has been unmaintained for a while

Overview

TimeVault is a simple front-end for making snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time. Restore functionality is integrated into Nautilus - previous versions of a file or directory that has a snapshot can be accessed by examining the properties and selecting the 'Previous Versions' tab.

Snapshots are protected from accidental deletion or modification since they are read-only by default. The super-user can delete intermediate snapshots to save space, but files and directories that existed before or after the deletion will still be accessible.

TimeVault Snapshot

A snapshot is a copy of a directory at a certain point in time. Snapshots don't use space for the files that haven't changed but instead simply add a link to the same data on disk. When a file (link) is deleted, the link count for the data on disk is decremented. When it reaches 0 the data is marked free in the allocation table and new data can then be written to those blocks. As most allocations of data have only 1 file that links to them data is usually freed when its file is deleted.

Only files are hard-linked this way. In most filesystems directory hardlinks are disallowed because they can cause endless recursion. Apple specifically modified their system by adding mandatory recursion detection to prevent infinite loops, ostensibly purely for their backup software.

This is a page about Time Machine and covers how it works. TimeVault has a similar method of creating snapshots.

(Possibly still some issues in this!)

After installing the .deb file, there are two steps required to complete installation:

in the command box, you can put whatever you like in the comments box. After you have done this if you log out and back in again you should magically have the TimeVault notifier app sitting in your systray. Right click on it and go to preferences to configure TimeVault as you wish.

Configuration

When you start the TimeVault Notifier for the first time the tray icon will be greyed out and if you hover over it it will say that it is unconfigured. Listed below are the steps needed to configure TimeVault:

There are three tabs: General, Include and Exclude.

General

Include

Exclude

When you have finished making the necessary changes press the save button and TimeVault should pop up a message saying

You have included new directories in the TimeVault. File signatures will now be computed.

Click ok in this box and TimeVault should be active and will start watching your files.
