Maybe the -E option helped you out there.

-E Prevents xfsrestore from overwriting newer versions of files.
The inode modification time of the on-media file is com‐
pared to the inode modification time of corresponding file in the dest directory.
The file is restored only if the on-media version is newer than the version
in the dest directory. The inode modification time of a file can be displayed
with the ls -lc command.
