[CentOS] claiming unsused space back

[Leroy Tennison]

I realize this is wandering off-topic but, if you have found Debian commands, you're doing better than me.  What are they?  Also, are you allowing dd to totally fill the partition (what I have found on the web as a recommendation)?  If so, is the OS surviving acceptably?

Hi,

 I´m running a CentOS server in a VPS. Backups of the VPS take quite
much space if I don´t claim unused space.

 Currently I´m using dd if=/dev/zero of=/mytempfile and remove that file
to claim that unused space. Any automatic way of doing a similar thing
in CentOS? I have googled for it but I have only found Debian commands.

 Thanks in advance!

 Miguel
