Overview<\/h2>\n

When you attempt to perform a backup to a Common Internet File System (CIFS)-mounted drive, you may receive errors that resemble the following example:<\/p>\n

\n
\/bin\/cp: failed to preserve ownership for<\/span> `<\/span>': Permission denied \/bin\/cp: failed to preserve ownership for `'<\/span>: Permission denied<\/code><\/pre>\n<\/div>\n
These Permission denied<\/code> errors may result from missing extended attributes on the CIFS-mounted drive.<\/p>\n
\n

\n
For more information about CIFS, read our Backup Configuration documentation.<\/p>\n<\/p><\/div>\n<\/div>\n
Resolve the error<\/h2>\n
To resolve the permission denied errors for the CIFS-mounted drive, perform the following steps:<\/p>\n
    \n
  1. \n
    Edit the \/etc\/fstab<\/code> file so that the CIFS-mounted drive uses the user_xattr<\/code> option. This will resemble the following example:<\/p>\n<\/p>\n

    In this example, line 4 displays the CIFS-mounted drive entry.<\/p>\n
      \n
    • The local user owns the mounted files.<\/li>\n
    • The CIFS drive\u2019s access credentials reside in the \/root\/.cifs<\/code> file.\n
      \n
      Important:<\/div>\n
      \n
      We strongly<\/strong> recommend that you store your CIFS-mounted drive\u2019s access credentials in a separate, secure file.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n<\/ul>\n<\/li>\n
    • \n
      Run the remount mount<\/code> command to remount the CIFS-mounted drive.<\/p>\n<\/li>\n
    • \n
      Run the lsattr \/CIFS_mount<\/code> command to add the extended attributes.<\/p>\n
      \n
      Important:<\/div>\n
      \n
      The mount does not<\/strong> support extended attributes if the lsattr \/CIFS_mount<\/code> command returns the following error:<\/p>\n
