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.</span></div>

Hi,<br>
<br>
Excerpts from Priyanka Sharma's message of Sat Apr 03 23:35:29 +0530 2010:<br>

<br>
</div>I believe there is such a tool:<br>
<a href="https://wiki.ubuntu.com/TimeVault" target="_blank">https://wiki.ubuntu.com/TimeVault</a><br>
Although I'm not sure how much activity exists on that.<br>
<br>
And I'm sure every red blooded Linux user tried to build a backup system<br>
once. I worked on a project myself called Project Sauron, which aimed to do<br>
most of the things you're suggesting, it used git backing up changes<br>
periodically on specified files, and providing the ability to jump to any<br>
specified point by reverting a specific file to the commit.<br>
<br>
You might find more luck with bup - a system that uses git packfile format<br>
for backing up:<br>

Which is actually written in python.<br>

Thanks,<br>
