Introduction 

The Macintosh File System iDataAgent is the backup and restore vehicle for file system data (i.e., files and directories) residing on Macintosh computer systems. This File System iDataAgent provides backup and restore support for different kinds of data in what is often a heterogeneous network environment. The following figure shows one such example.

Supported Data Types

In general, the Macintosh File System iDataAgent supports data protection operations for the following data types: Apple Filing Protocol (AFP), Hierarchical File System (HFS), HFS+, ISO 9660, Mac OS Extended, Mac OS Extended (Journaled) [for Mac OSX 10.3.x], MS-DOS, Network File System (NFS), Universal Disk Format (UDF), and Universal File System (UFS).

The Unix File System iDataAgents can restore Macintosh file system resource fork data. For an overview, see Restore Macintosh File System Resource Fork Data.

In addition, the following tables provide specific information on the effect of supported data types on Macintosh File System iDataAgent backups and restores. The right-most column in each table provides references to the appropriate commentary, requirements, and/or restrictions for each scenario. If the reference is flagged by "*", be sure to check the referred section for further information if necessary.
