Hi Lars,

It copies the inodes and directory contents and other metadata. 
I restore it here and run xfs_repair over it to see how it 
failed. xfs_repair only operates on metadata and does not 
check data.

Currently, it does not obfuscate file names if there is a
privacy/confidentiality concern but that is a feature I
intend on adding later.

Regards,
Barry.
