    Good Day,

    I m seeing a wierd pattern when i take a backup of one of my KVMs.

    I used to have over 40G of data in that kvm centos, then removed all those files/folders not there is only 1G of data in that server. I took a backup of that kvm on proxmox and it took forever and i see that the backup file is over 35G?

    What might be the problem here

    here is df -h on that kvm centos;
    [administrator@svn ~]$ df -h
    Filesystem Size Used Avail Use% Mounted on
    47G 880M 44G 2% /
    tmpfs 120M 0 120M 0% /dev/shm
    /dev/vda1 485M 32M 429M 7% /boot

    This is because when you delete a file, the datas are not deleted from the disk,only the file entry in the filesystem.

    you can use "zerofree" tools the clean the disk. (must be unmounted)
