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.

What is a Snapshot
Note:
The following applies to TimeVault versions below 0.4.0. TimeVault has changed significantly since then, so the documentation will have to be rewritten accordingly.
Pre 0.4.0 Documentation:
(Working to bring this up to pace) After installing the .deb file, there are two steps required to complete installation:
You must configure TimeVault, the backend will start automatically but the notifier needs to be started: To get the notifier app to start in your systray whenever you log in you can add it to your startup programs in System>Preferences>Sessions in the tab Startup Programs you should have an option to add a program click that, name it TimeVault and put:
'/usr/bin/timevault-notifier'
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
There are four tabs: General, Include, Exclude, and Management. General
Enable Automated Snapshots: By default, TimeVault will not automatically take snapshots of your system. Checking this box will tell it to automatically take daily snapshots.
- Allow users readonly access to snapshots: If this box is not checked, only the superuser (root, or a sudoer) can access the snapshots. If it is, then users will be able to browse snapshots according to their rights. So a user that does not have access to a directory or file will not have access to the snapshot of the directory or file. Note that only read access is granted - snapshots cannot be changed except by the root user (in the Management tab)
- Snapshot Root Directory: Where to store the snapshots. Ideally, you should pick a directory that is mounted onto another physical drive from the data you are backing up. This is so that, in the case of a hard-disk failure, the backups will remain intact (unless the drive containing the backups fails, in which case the current version of the data remains).
Include
Backup paths are listed here. Every directory that you want to be snapshotted should be added to this list.
Exclude
Paths or patterns to exclude from the snapshots should be listed here
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 increment the link count for them. On Linux, when a file is deleted, the link count is decremented, but it isn't actually removed until the link count hits zero.
Only files are hard-linked this way. Directories have to be recreated for technical reasons (since a hard-link is actually the file it points to, you would find yourself in a completely different path if directories were hard-linked).

Change Log
Version 0.6.7
- Automatic reconnect to server (if restarted) from status icon
- Changed debug message system to allow for varying degrees or verbosity (use --verbose multiple times for more debug information)
- Added metadata saving system (this one is a pretty big change), so that file changes from apps like Beagle and Tracker (who ultimately churn through hundreds of MB a day) are not saved.
- Added metadata caching dictionary so it needs to be queried only once for changed files per session. Dictionary auto-trims after 32K entries.
- Added better information printout in Nautilus' property pages
- Added Snapshot Browser handling for metadata (checkbox to hide metadata and show real changes only)
- Fallback mechanism for determining if a file is text in the absence of a mime-type (e.g. extensionless files).
- Diff viewer in Snapshot Browser
Version 0.6.8
- Snapshot picker improvements - filter by dir or file, or by right-clicking on row
- Improved use of SQLite API (i.e. rewrite all queries so parameters are escaped by DB engine) - avoids SQL injection through crafting malformed filenames
Version 0.6.9
- Internal versioning - not for release
Version 0.6.10
- Relatively seemless configuration reload: Reload configuration when changed without restarting Nautilus, Notifier, or server
More config options: Enable/disable nautilus integration from TimeVault Prefs dialog.
- Pending Snapshots Browser: When notifier is clicked, list pending snapshots (abort snapshot functionality not yet implemented)
- Change visualization of different snaptypes in picker so that the total height is still logarithmic(base 1.5), but the ratio is linearly proportional - this makes it easier to see what's happening
- Pending files are resumed if the server restarts
Gracefully add metafile/baselines to snapshotter queue (v. <0.6.10 would do so more aggressively, thereby causing unacceptably long lags when initiating a metadata sigs for newly added paths)
- Fixed a bug where files with carriage returns in them (yes - believe it or not they exist) can be backed
- Efficiency improvements.
Version 0.6.11
- Fixed Baseline generation bug where you could not generate them from the Prefs screen
Added a Take Baseline button in Prefs->Include
- Added a Real and Meta filters in Snapshot Browser
Version 0.6.12
- Compatibility changes for Python 2.4 on Gentoo
Version 0.6.13
Take Baseline button properly connected in Prefs->Include
Version 0.6.14
- Small bug fixes
Version 0.7.0
Alpha Version for bug testers (new point release - no compatibility with saved snapshots from 0.6 branches). If someone really needs a 0.6 => 0.7 importer written, please let me know.
- Revision of underlying layers (Config, Daemon)
- Efficiency improvements
- Live update on Upcoming Snapshots browser
- Paths restructured to allow hiding of snapshots taken by others
- Some parts are bound to be broken

KDE-port: I've done the GUI for KDE port, the code obviously needs a fair few changes but it's on the back boiler for a few weeks. -- KieranHogg
