Overview

The following page describes the agent-specific restore options. Additional restore options are accessible from the Related Topics menu.

The Macintosh File System iDataAgent supports data recovery operations for the following data types:

• Apple Filing Protocol (AFP)
• Hierarchical File System (HFS)
• HFS+, Universal Disk Format (UDF)
• ISO 9660
• MS-DOS
• Network File System (NFS)
• Universal File System (UFS)

In addition, sometimes depending on particular scenarios, data recovery support may or may not be available for the following items, among others:

• Executable files
• Files with special characters
• Sparse files

See Effect of Data Types on Restores by Macintosh File System iDataAgents for more information.

For the Macintosh File System iDataAgent, restore operations can be performed from the client, iDataAgent and backup set levels in the CommCell Browser.

When the root file system is lost, a full system restore is required. See Restore Data - Macintosh File System iDataAgent - Full System Restore for more information.

Restore Considerations for this Agent

When restoring any Macintosh File System data, keep the following in mind:

• You can restore Macintosh File System data to any eligible Darwin client computer. Also, you can restore this data to a Unix machine or vice-versa, but you cannot restore the data to a Windows machine or vice-versa.
• UFS files with holes (sparse files) can be restored, but HFS+ files with holes cannot be restored.
• When restoring files with holes, the null blocks that form the hole may not be in the same location in the file relative to the data. The file size is not changed, but the number of disk blocks may change.
• Restore operations on files that include the "[]" character sequence and/or the "\" character fail when restored without browsing. In order to restore these files via a browse operation, the directory that contains these files, or a higher level directory, must be selected in the browse window as content to restore.
  For example, if there is a file named file[]name in the /opt directory, then you must select the /opt directory or any directory that contains /opt for restore. If you select only the file, the restore will fail.

• Do not set a quota for an object (such as a volume, directory, or user) that is lower than the amount already used. Doing so may cause improper results for data protection or recovery operations.

• When restoring a default subclient after a full backup, the Latest Backup Data dialog window incorrectly displays top-level directories for any user-defined subclients that have not been backed up. Attempts to restore data from user-defined subclients that have not been backed up will fail.
• If you do a framed browse (i.e., select both a begin and end date/time for the browse) and select the entire resulting data tree for restore by selecting the top-most (or root) node, an erroneous error message is displayed stating that the restore operation failed. Restores under these circumstances are successful regardless of the error message. To avoid this error message, select the data to be restored from the next-to-highest level in the tree.

• An advanced restore option allows you to filter out mount points that are part of the backup data during the file system restore. This is useful in cases where you did not mount all the mount points and do not want to fill up the holding file system during the restore. Using this option will ensure that data belonging only to the restoring file system will be restored.

Finally, see Effect of Data Types on Restores by Macintosh File System iDataAgents for more relevant information.

Restore Destinations

By default, the Macintosh File System iDataAgent restores data to the client computer from which it originated; this is referred to as an in-place restore. You can also restore the data to another Client computer in the CommCell. Keep in mind the following considerations when performing such restores:

• The destination client must reside in the same CommCell as the client whose data was backed up.
• Note that when you perform restores other than in-place restores, the restored data assumes the rights (i.e., permissions) of the parent directory.

The following section enumerates the types of restore destinations that are supported by the Macintosh File System iDataAgent. See Restore/Recover/Retrieve Destinations - Support for a list of Agents supporting each restore destination type.

In-Place Restore

• Same path/destination

Out-of-Place Restore

Keep in mind that out-of-place restore operations are also subject to the conditions described in Cross-Platform Restores.

• Same path/destination
• Different path/destination

Restore Data Using a Map File

• Restore Data Using a Map File

Cross-Platform Restores

• Same Operating System - Different Version

Restore to Network Drive/NFS-Mounted File System

Besides restoring data to a client computer’s local drive, you can also restore data to an NFS-mounted file system. (See Restore to Network Drive/NFS-Mounted File System for comprehensive information.)
