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.
