1	Overview
The Agent for AIX is installed on each AIX system that you want to protect. Using Portal or the legacy Windows CentralControl, you can manage the Agent, back up data to a vault, and restore data from the vault.
1.1	Release History
Version 7.51.7267, August 2, 2019
Version 7.50.7262, June 11, 2018
1.2	Compatibility
Portal	AIX Agent 7.51 is supported with Portal version 8.30 and later.
Important: You can only register a newly-installed AIX Agent 7.51 to Portal version 8.30 or later. However, if an AIX Agent is already registered to a previous Portal version, you can upgrade the Agent to version 7.51 and it remains registered to Portal. To determine your Portal version, sign in to Portal and go to Need Help > About.	
Windows CentralControl	You can manage AIX Agent 7.51 with Windows CentralControl version 8.01 or later. 
Important: Changing job configurations using Portal and Windows CentralControl alternately is not supported. Do not manage the same Agent using both Portal and Windows CentralControl. 
Because important security fixes and new features are available in Portal, we recommend using Portal to manage the Agent instead of the legacy Windows CentralControl. 	
Director	AIX Agent 7.51 is supported with Director version 8.00 and later. 	

1.3	Supported Platforms
This Agent is supported on the following AIX versions:
•	AIX 7.2 TL 0 or later
•	AIX 7.1 TL 5 or later
•	AIX 6.1 TL 9 or later
The XL C/C++ runtime environment for AIX version 13.1.3.1 or later must be installed. 
Note: For AIX 5L version 5.3 or 5.2, please use AIX Agent 6.00a.
2	New FEATURES
2.1	New Feature in Version 7.51
•	Information provided with the Agent has been updated.
2.2	New Features in Version 7.50
•	Security improvements have been made, including using SHA-256 for communication between the Agent and Portal or vault, and TLS support for SMTP. 
•	Job names can now be up to 30 characters in length.
•	When restoring files or folders to an alternate location, the Agent no longer restores all parent directories. For example, if you back up the file /a/b/c/d/file1.txt (including the full path), and restore the file to a new /restoreA directory, the file will be restored to /restoreA/file1.txt. With previous Agent versions, the file would be restored to /restoreA/a/b/c/d/file1.txt.
3	INSTALLATION NOTES
3.1	Installation Requirements
•	CPU - IBM Power5 or greater
•	RAM - Minimum of 512 MB recommended
•	At least 410 MB of free space for a new (fresh) install. An upgrade may require more. If there is not enough disk space, the install will display a message.
By default, AIX systems have very small volumes. Ensure that the volume for the AIX Agent is large enough, and that the /opt volume is large enough to facilitate the installation. If the available disk space is insufficient for a complete installation, the installation directory will roll back to its original state. 
•	A TCP/IP stack
3.2	Install
The AIX Agent installation kit is provided in the following file: Agent-AIX-7.51.7267.tar.gz
The default installation directory for this Agent version is /opt/BUAgent.

3.3	Upgrade
You can upgrade to this Agent version from AIX Agent version 6.01 or 7.50. To upgrade from an earlier AIX Agent version, upgrade to version 6.01 first, and then upgrade to version 7.51.
4	FIXES AND KNOWN ISSUES
4.1	Fixes
4.1.1	Fixes in Version 7.50
During a restore with the Do Not Overwrite option selected, the Agent does not attempt to restore a directory (and its child directories and files) to a location that has a symbolic link with the same name. During a restore with the Rename Incoming option selected, if the target location has a symbolic link with the same name, the Agent creates a new directory with the extension .0001 and restores all child directories and files to the new directory. (EV-21743)
When you try to restore files to a directory where the path length exceeds the PATH_MAX value, the restore now fails with an informative error message. (EV-21615)
The Agent prevents rare problems with backups that have been deferred more than once. (EV-6157)
An error message no longer appears in the backup log when the Agent searches for a file that has been deleted from the system. (EV-8574)
The Agent installation kit does not allow you to downgrade the Agent version. (EV-17994)
An extra space is no longer added in timestamps in XLOG files. (EV-22006)
4.2	Known Issues
If a job is seeded to a vault using Agent version 7.34 or earlier and reseeded using Agent version 7.50 or later, the vault storage size for the job data cannot be reduced. (EV-25740)
This Agent version cannot back up or restore extended attributes on file systems that support them. (EV-22357) 
If the Agent is running on a WPAR, and you try to install the Agent on the global LPAR where an Agent is not installed, the installer detects that the Agent is running and asks you to stop the services.
WORKAROUND: When installing the Agent on the LPAR, when you are prompted to stop the Agent, enter Y. The Agent installation will continue but Agent services on the WPAR will not stop and running jobs will not be affected. (EV-21497)
If an NFS mount is disconnected while an NFS backup job is running, the backup job may become unresponsive. (EV-19348)
This version of the Agent does not support EFS:
•	The Agent backs up encrypted files in plain or unencrypted form. Attributes such as cipher algorithms and EFS access lists are not backed up.
•	When the Agent backs up encrypted directories (i.e., with inheritance set), the inheritance is removed from the directories.
•	Files that are restored to encrypted directories will become encrypted using the cipher algorithm that previously applied to the directory.
Full system restores fail when the Technology Level (TL) of the target system is lower than the TL of the source system. For successful system restores, the TL of the target system must equal or surpass the TL of the source system. (14847)
You may be unable to register to the vault with the AIX Agent when multiple IPs are bound to one NIC. 
WORKAROUND: Set the maximum buffer size for "sb_max" (for a TCP or UDP socket) in the TCP parameters to a value larger than 512 kB. You can display the sb_max value using "no -o sb_max". Refer to the MAN pages for more information about the "no" command and how to change the value. (8993)
