Safe Delete

[Paskinel]

Hello to everybody!
1) Is there any program that Safely Erases files/folders?
(i.e. by using DoD-3, DoD-7, Gutmann 35 methods)
OR
Do I have to use commands each time?

2) About KleanSweep:
-Which are the safe-to-delete entries?
In other words, what files do I check,
before KleanSweep begins searching for Junk files?

Re: Safe Delete

Not sure what you mean by safe delete.

If what you want to do requires execution of a number of processes and you cannot be asked to type the same sequence in time and again you could for one put an alias into your .bashrc - for more info search bashrc in this forum. You can also put scripts into your .bashrc

Re: Safe Delete

Take a look at the "secure-delete" package, which you can download from the repositories.
The program "srm" is part of that package, and may do what you want.

You can also use dd and dcfldd to accomplish the same thing, with a little more fiddling.

If you are concerned about data security, you might want to install an encrypted file system such as encfs or truecrypt, also available in the repositories.

Re: Safe Delete

1) I'm looking for a program that will
Safely(=Secure=No Possible Recovery) Delete/Erase a File or a Folder.
There are special Overwriting methods (patterns) for this:
DoD-3, DoD-7, Guttman-35 etc.
-Is there such a program in Linux?

2) What about KleanSweep?
Which are the safe-to-delete entries?
In other words, what files do I check,
before KleanSweep begins searching for Junk files?

Re: Safe Delete

I googled "safe delete linux" and came up with shred. You should have it installed already. For more info type

man shred

Re: Safe Delete

man shred: In the case of ext3 file systems, the above disclaimer applies (and
shred is thus of limited effectiveness) only in data=journal mode,
which journals file data in addition to just metadata. In both the
data=ordered (default) and data=writeback modes, shred works as usual.
Ext3 journaling modes can be changed by adding the data=something
option to the mount options for a particular file system in the
/etc/fstab file, as documented in the mount man page (man mount).
In addition, file system backups and remote mirrors may contain copies
of the file that cannot be removed, and that will allow a shredded file
to be recovered later.


Keep it simple: just use dd (dcfldd from Live Helix CD).

Example, my how-to here:
dd Command

EXPERIMENT #4: Wipe a file before deleting it (to prevent recovery).
