Actually most journaling file systems in Linux use block logging and it would be probably hard to get specific file names out of a random collection of logged blocks. And even if you could they would hit a lot of false positives since everything is rounded up to block level. With intent logging like in XFS/JFS it would be easier, but even then costly :- e.g. they might log changes to the inode but there is no back pointer to the file name short of searching the whole directory tree. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
