Backing up Macintosh computers

After making backup selections, job properties for the Macintosh computer backup jobs should be set. Job properties specifically targeted to Macintosh backup jobs are found in the Job Properties pane under Linux, Unix, and Macintosh.

Use the following steps to set the backup job properties.

To back up a Macintosh computer

  1. After making backup selections from the Macintosh computer, from Properties, under Settings, click Linux, Unix, and Macintosh.

    The following options appear:

    Preserve change time

    Use this option to prevent the Remote Agent from changing an object's (files and directories) attributes when a backup occurs. Normally, during a backup, Backup Exec preserves an object's last access timestamp by resetting the last access timestamp to the value before the backup occurred. When Backup Exec modifies the objects' last access timestamp, the Macintosh operating system internally updates the object's "ctime." An object's ctime is the time when an object's attributes (permissions, timestamps, etc.) have been modified. If the attributes are not changed by the Remote Agent after a backup, the object's ctime will not change. This option does not affect object attributes set during restore operations.

    Follow local mount points

    Use this option to have Backup Exec follow local mount points when backing up data. For more information on local mount points, see your Macintosh documentation.

    Follow remote mount points

    Use this option to have Backup Exec follow remote mount points when backing up data. For more information on remote mount points, see your Macintosh documentation.

    Back up contents of soft-linked directories

    Use this option to back up the contents of directories that are linked using soft links.

    Macintosh computers use many soft-links, some of which may point to parent directories. Selecting this option can result in duplicate data being backed up to tape, and it can also cause backup jobs to continue indefinitely.

    This option can be useful in certain situations. For example, you can use this option to back up a single directory that contains soft-links to data you want backed up.

    When this option is selected, the soft-links themselves are not backed up but the data they point to is.

    When this option is not selected, the soft-links are backed up, but the data is not.

    For more information on soft-linked directories, see your Apple Macintosh documentation.

    Lock remote files

    Use this option if the Remote Agent requires exclusive access to the files on remote systems connected through Network File System (NFS).

  2. Make the appropriate selections or use the default selections provided.

  3. Click General in the Properties pane of the Backup Job Properties screen.

  4. In the list box for Backup method for files, select Full - Back up files - Using modified time rather than Full - Back up files - Using archive bit (reset archive bit), as the concept of an archive bit is not valid in Macintosh environments.
