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
