hi
I have Debian Sarge installed on ext3
by mistake I've deleted some important TEXT files
how I know ext3 data structures do not support any method of undeleting
I've heard there is only a one possibility using grep, but knows someone how it works ?
which system should have possibility of undeleting ?
I'd like to setup a new Debian Server using a system with the possibility of undeleting.
greetings

Undeleting on ext3 is not straightforward, the most you can do is to check the blocks and see if they contain anything useful. This means checking the physical device for pieces of data you know to be in your deleted file, and hope for the best. I'd say the undeleting on ext3 is destined to be futile.
Ext2 can be undeleted, however, so if you use only ext2 FS, there are a bunch of tools you can use for undeleting.
And no, you can't mount an ext3 FS as ext2 to use these tools.

I think none of the modern journalling file systems support any undelete mechanisms.
You could write a shell script which moves files to a directory called ~/.trash or something. Then, using this script instead of "rm" to "delete" a file, this technique would result in a similar behaviour as the trash bin in desktop systems like Gnome or KDE.

mority, the script you described would really make sense, however, it isn't protecting you from other means of deleting files, like from mc. When I go cleaning up some mess on the HD, I usually use mc to do so, because this way I can see the files and directories what I want to delete. Should I accidentally delete something important, the script won't help me.
I think that the effort would be put into preventing important files from deleting, like setting the immutable attribute on them. This way, any change, including deletion would require you to clear the attribute first. Of course, if you need to change the file contents often, this could be irritating....
