“Currently the network share backup support is limited to only Windows network shares. Problems might be encountered if you use this feature to backup CIFS-compatible shares such as Samba, Snap Appliance Filers or Mac OS X Shares. This includes the inability to backup files with certain filename encoding or lengths, changing the filename while backing them up, or not restoring the permissions correctly”.
