macOS Limitations

Resource Fork Files

Resource fork files cannot be restored with AhsayOBM installation on macOS 10.8 above.

Case-Insensitive File System

For volumes with a case-insensitive file system, target file of a symbolic link will be backed up twice (in both upper case and in lower case), hence, doubling the backup quota storage requirement.
