Single File Reversion To Or From Symbolic Links Using Snaprestore Not Supported; Changes To The Data Protection Tape Backup And Recovery Guide; Support For Smtape Backup Of Compressed Volumes; Designating Range Of Ports For Ndmp Data Connections - IBM N Series Manual

The Snapshot copy reserve value is 5 percent of the volume size instead of the
20 percent stated in the "What the Snapshot copy reserve is" topic.
Single file reversion to or from symbolic links using SnapRestore not
supported
You cannot perform single file reversion to or from symbolic links using
SnapRestore. This information is not included in the "Reverting a file to a
selected Snapshot copy" topic in the Data ONTAP 8.0 7-Mode Data Protection
Online Backup and Recovery Guide.

Changes to the Data Protection Tape Backup and Recovery Guide

Some additional information about tape backup features has become available
since the previous revision of the Data ONTAP 8.0 7-Mode Data Protection Tape
Backup and Recovery Guide.
v "Support for SMTape backup of compressed volumes"
v "Designating range of ports for NDMP data connections"

Support for SMTape backup of compressed volumes

Starting with Data ONTAP 8.0.1, SMTape supports backup and restore of
compressed volumes.
The information about the lack of support for compressed volumes in the
Data ONTAP 8.0 7-Mode Data Protection Tape Backup and Recovery Guide is no
longer applicable.

Designating range of ports for NDMP data connections

Data ONTAP supports a designated range of TCP/IP ports that can be used
for NDMP data connections in response to NDMP_DATA_LISTEN and
NDMP_MOVER_LISTEN operations.
Data ONTAP 8.0 7-Mode and earlier versions do not support data migration
by using ndmpcopy command and three-way tape backups in environments
where the source and destination networks are separated by a firewall. This is
because the data or mover port that is used in a data transfer is unpredictable.
Starting with Data ONTAP 8.0.1, administrators can designate range of ports
that can be used for NDMP data connections in response to
NDMP_DATA_LISTEN and NDMP_MOVER_LISTEN operations. Therefore,
Data ONTAP enables you to perform data migration by using ndmpcopy
command and three-way tape backups even in environments where the
source and destination networks are separated by a firewall.
