I do not see any information as to whether I can backup raw partition on Linux using remote agent of BackupExec. I am trying to back up /dev/sda8 volume.
The only supported filesystems are Ext 2, Ext 3, Reiser FS, JFS, and VxFS. You may wish to go to http://enhancement.veritas.com/, and submit this as a feature request for consideration in a future release.
