[pbs-devel] PBS File Retore for NTFS with deduplication enabled leads to corrupted files

[Daniel Koch]

Hello List,

Current situation:

Using PBS for NTFS with the de-duplication feature enabled (https://docs.microsoft.com/en-us/windows-server/storage/data-deduplication/overview) results in
corrupted file restores.

ntfs3 can't handle de-duplicated file systems atm.

ntfs-3g by default is not aware of ntfs'es de-duplication but provides plugins for those features:

Is there any chance that the restore kernel will use ntfs-3g over ntfs3 with dedup capabilities? The de-duplication feature of NTFS is widely used and people don't seam to be aware that their backups are actually corrupted.

Restoring the whole disk image will be fine tho.

Kind regards,
Daniel
