Re: [Lilux-help] Ext3

It will be like a backup that you can restore whenever you want. http://batleth.sapienti-sat.org/projects/FAQs/ext3-faq.html states: """"""""""""""""""""""""""" Q: How can I recover (undelete) deleted files from my ext3 partition? Actually, you can't! This is what one of the developers, Andreas Dilger, said about it: In order to ensure that ext3 can safely resume an unlink after a crash, it actually zeros out the block pointers in the inode, whereas ext2 just marks these blocks as unused in the block bitmaps and marks the inode as "deleted" and leaves the block pointers alone. Your only hope is to "grep" for parts of your files that have been deleted and hope for the best. """""""""""""""""""""""""""" The grep method does work for text files. It just implies searching everywhere in the partition to grab some chucks of text. I am afraid to tell you that for binary files, like jpg, that should not work that good. Be aware that if ext2 allows some recovering, ext3 deletes most useful things. The file pointer are altered so that you cannot guess where the files are. Plus, if you made some disk access you (or your system) may have scratched the previous data.
