Does a restore from a NTFS backup restore import stuff such as UID,GUID,permissions etc to a Linux filesystem?

Short answer: NO

Long answer: unless the backup is in a Unix/Linux format, like a .tar file, ntfs doesn't have a UID/GID and/or most of Unix permissions. Furthermore NTFS doesn't support links, neither HARD nor SYMBOLIC ones. So a "file by file" backup has lost all of those on the NTFS disk/partition.
Of course inside a backup format like tar, cpio or some dedicated format from a Linux backup tool all of those values will be stored inside, so can be restored. And when you use such an archive format, the destination file system doesn't matter as only that archive itself is stored there, not the backup'ed file (themselves).

Using a program that saves the unique metadata will save filesystem attributes across any underlying filesystem.

Most compression programs also have a built in parity check to assist with data protection.
