[msg #3263 filesystem.cpp 1029 PSDBG 5] Failed to find the character device path for blk device [<mount_point>]

Cause

There is a typo in /etc/filesystems that is making the backup to fail to discover the correct device name associated to one of the mount points. In this particular case the following incorrect line is in /etc/filesystems:
 
soze            = +100G

The previous is not a valid attribute and therefore it should be removed from /etc/filesystems.

Resolution

  • Check /etc/filesystems looking for invalid entries or typos.
  • Remove the invalid entries or correct the typos if they are found.
  • Do a new backup.
