Hi Rrmarino,

It is not an incremental dump. But .... It is two removable
backups in a row.  Due to this bug

https://bugzilla.redhat.com/show_bug.cgi?id=1257018

The backup drive mounts on /dev/sda the first time,
gets removed and the second drive mounts on /dev/sdc.
This error occurred on the second drive.

Maybe it is using this catalog?
