Guest Agent Restores

You can restore files using an agent installed in the destination client or virtual machine. This option supports recovery of larger amounts of data and generally offers the best performance, but it may not always be possible.

Prerequisites

  • For Windows clients:
    • The destination client must have a Windows File System iDataAgent installed (in full or restore-only mode). For more information, refer to Installing Restore Only Agents.
    • The version of the file system agent must be the same as the version of the Virtual Server Agent.
  • For Linux clients:
    • The destination client must have a UNIX File System Agent installed (in full or restore-only mode). Existing deployments using an Image Level Agent (deprecated) are also supported.

Considerations

  • For Linux clients:
    • The Preserve Source Paths option is not supported when you are restoring files or folders from a virtual machine.
    • The Restore ACLs option restores basic user/group/world permissions and timestamps; advanced permissions are only restored when using a guest agent together with a File Recovery Enabler for Linux.
    • If the original user for a folder does not exist on the destination, restored files will have the user ID instead of the user name. Otherwise, folder user names and permissions are preserved.
    • Symbolic links can be restored if the source files are also restored, but they will use the timestamp of the restore operation instead of the original timestamp. If the source files are not restored, symbolic link files are restored but without links; as a result the linked data cannot be read.
    • Hard link files can be restored; if source files are also restored any corresponding link files use the same index node (inode).
