Summary | 0000804: Support secure delete of files | ||
Revision | 2016-04-20 16:14 by Ulrich Schwab | ||
Description | A normal delete removes only the entry in VTOC or INODEs but the data on disk is still there. A secure delete will overwrite the file data before the file is removed. NOTE: The file needs to be opened with O_DSYNC or O_SYNC and might require several passes before the file is finally removed. See: http://srm.sourceforge.net/srm.html [^] or man srm after pacman -S srm |

Description | A normal delete removes only the entry in VTOC or INODEs but the data on disk is still there. A secure delete will overwrite the file data before the file is removed. NOTE: Also the write needs to be flushed and written to disc otherwise the operating system might mark the write as "no need to actually write this on the disc, it is deleted anyway" and the data on disc still remains intact |
