Hello, Last night I damaged a plain UTF-8 HTML file (I copied by accident a JPEG file over it) and it turned out that the backup was done a month ago. I learned my lesson from this re/ doing backups more often of files I'm working on... Maybe there is a chance that the disk blocks are still not overwritten, what would be the best way to look for them block by block and if it contains certain string "foo-bar" having the block number from the beginning of the device to get it back with dd(1) into a file. Any scripts or tools for this? Thanks matthias -- Matthias Apitz, ✉ guru@unixarea.de, http://www.unixarea.de/ +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub
