backup USB - Problem Volume data

  • Hello.
    I use BAckup USB for synchronizing 2 disks.
    But the synchronisation targer consume very more data volume than source !!!


    Is there because source is a urbackup disk with i think a lot of symbolics links ?


  • You mean the USBbackup plugin, right?

    Option delete target file which does not exist is set

    I had assumed that this option was not set. If you want an exacty copy of the source, then the delete option must be set.


    Therefore I would propose to delete the target disk completely and then give the USBbackup plugin a second try.

  • You should switch off "Silence". Then you get a very detailed email report, what was going on.

  • Hello
    i have the same problem after deleting file et trying second time.


    I think because i am cloning a urbackup backups
    There is a lot of hard link in incremental backups.


    I think rsync in plugin does not preserve hardlink and symlink and copy files directly more than one time


    there is a lot of discuss about subjet
