	     			ARCserve V4.02
                                  10/7/93




	This readme file describes the changes that have been made to 
	ARCserve since the 4.0 Release.

	SMS
	===

        The default mode for ARCserve Unattended Backup is Partial SMS
	mode.  This means that only OS/2, NFS and FTAM name spaces will 
	be backed up with SMS.

        To use Full SMS mode, use the command line parameter SMS when
	loading ARCSERVE.NLM (type LOAD ARCSERVE SMS).

        If you are backing up NetWare 4.01 servers, or remote 3.1x servers
	with MAC name space support, then Full SMS mode is recommended.
	If you plan on using SMS, you must load TSA311, TSA312 or TSA400
	on the	target servers.  First LOAD SYS:SYSTEM\DR\SMDR31X (or 
	SMDR for NetWare 4.01) and then LOAD SYS:SYSTEM\TSA\TSA311 (or
	TSA312 for NetWare 3.12 or TSA400 for NetWare 4.01) on each 
	target server. 	

	Also, if you are backing up a NetWare 4.01 server, when prompted 
	for a login name, you may use all names that exist in bindery
	emulation, except SUPERVISOR, since SUPERVISOR doesn't also exist
	under NetWare Directory Services.

        If you do not want to use SMS, you may load the SMDREMUL.NLM in
	place of SMDR31X.NLM or SMDR.NLM on the host server.

        
	Running ARCserve 4.02 on NetWare 3.11
	=====================================

	You must use CLIB.NLM version 3.11d or later.  If an older CLIB is 
        already loaded you must UNLOAD CLIB first.

	You must LOAD SYS:SYSTEM\DR\SMDR31X before loading ARCSERVE.NLM.

	=================================================================

	Running ARCserve 4.02 on NetWare 3.12
	=====================================

	You should use SMDR31X.NLM dated May 13, 1993, which is provided
	with ARCserve 4.02.  The SMDR31X.NLM dated June 15, 1993 will cause
	the server to abend when unloading and then reloading TSA312.NLM
	at the end of a backup job.

	===================================================================

	Running ARCserve 4.02 on NetWare 4.01
	=====================================

	Before installing ARCserve:
	-------------------------- 	

	There is a patch to NetWare 4.01 on Netwire called dspat.exe. 
	This patch must be loaded prior to installing ARCserve to
	prevent the ARCserve NLMs from unloading when they are first loaded.

	The NetWare 4.01 server must have Bindery Emulation enabled. 
	Verify that it is enabled by typing "SET BINDERY CONTEXT" at 
	the file server console.

	Before running the ARCserve installation,  login to the 4.01
	server in Bindery mode by using the /B switch, 
	"LOGIN NW40/ADMIN /B".  This way ARCserve will use the standard
	Bindery names rather than the distinguished names of Directory
	Services.

	Installing ARCserve:
	-------------------	

	Install ARCSERVE.NLM and TAPEDRV.NLM in the normal manner.

	Running ARCserve:
	----------------

	You must LOAD SYS:SYSTEM\DR\SMDR before loading ARCSERVE.NLM.

	Before running the ARCserve Manager, be sure to login to the 
	server in Bindery mode.  All user names and passwords entered
	in Unattended Jobs Forms for NetWare 4.01 servers must be Bindery
	names and they must exist in Bindery emulation for that server.

	Limitations:
	-----------
	
	The Directory Services Database is not backed up by ARCserve.	

	Only one NetWare 4.01 server per Bindery Context may run ARCserve
	4.02 because there can only be one CHEY_ARCHSVR user and one 
	CHEY_A_Q in a Bindery context since all 4.01 servers in the same
	context share the same Bindery emulated objects.

	Installing ARCserve on Multiple NetWare 4.01 Servers:
	
	A different branch in the Directory Services tree must be created
	for each NetWare 4.01 server that is to have ARCserve 4.02 installed.
	Do this by creating a new Organizational Unit in the tree with
	NETADMIN.  If the server already is installed in Directory Services,
	uninstall using the INSTALL.NLM, then reinstall it in the new
	context.  Make sure the Bindery context of the server is set to 
	the new context. 

					Page 2

	Notes on the TSA for NetWare 4.01:
	---------------------------------
	
	When using the TSA400.NLM, the username and password for the 
	server is passed to the TSA.  The TSA400 will do a Directory
	Services' login, but the username and password in the ARCserve
	job form is a Bindery name and password.  This works as long as
	the name exists in Directory Services.  SUPERVISOR exists in 
	Bindery emulation but not in Directory Services and therefore 
	The TSA will not be able to login to the 4.01 server as SUPERVISOR.
	Create a SUPERVISOR equivalent in SYSCON or NETADMIN and use 
	that name.
 	
	===================================================================

	Running ARCserve 4.02 on NetWare SFT-III
	========================================

	The SMDR31X.NLM, TAPEDRV.NLM and ARCSERVE.NLM must be loaded in the 
        IO Engine.
	The TSAs do not currently work under SFT-III.

	===================================================================

	Bug Fixes and Enhancements
	==========================

	1. Support for SMS, DBagent, Userve and MACserve has been combined
	   into a single package.  DBagent, Userve and MACserve are options
	   which are sold separately. Previously packaged DBagent contains
     	   DBagent enabled ARCserve 4.00 update. You should not re-install 
	   the ARCSERVE NLM that comes with the DBagent. 			

	2. ARCserve now uses Novell's new SMS Target Service Agents and
	   Data Responders.

	3. Support for NetWare 1000 User version has been added.

	4. ARCserve now supports NetWare versions 3.11 or greater.  
	   NetWare 3.10 is not supported.

	ARCserve Manager
	================

	1. A SUPERVISOR or Equivalent will no longer be able to restore 
	   sessions without the Session Password.  The appropriate
	   password must be entered in order to restore the session.
	   WARNING:  If you forget your password, you cannot restore the
	   tape.

	2. Directory Attributes will be preserved for Attended 
	   Backup/Restore.

	3. For Unattended and Attended Archiving, files and directories 
	   that have no owners or are owned by the server will have the 
	   correct dates and attributes.

	ARCserve Server
	===============

	1. The ARCserve Server install will now create the group EVERYONE,
	   if it does not exist.

	2. A SUPERVISOR or Equivalent will no longer be able to restore 
	   sessions without the Session Password.  The appropriate
	   password must be entered in order to restore the session.
	   WARNING:  If you forget your password, you cannot restore the
	   tape.
 
	3. ARCserve is now compatible with the NetWare 4.01 DOS Requestor.
	
	4. SMS is supported on NetWare 4.01.
 				
 	5. User Space Restrictions will be preserved for Unattended Volume
	   to Volume Archive Jobs.
	
	6. Unattended Workstation Backups will exclude the Double Space
	   file on DOS 6.0 drives.

	7. MAC files will be restored to the correct MAC folder even when
	    other folders with similar names exist.

	8. The modification date and time on MAC folders on servers will
	   be reset after backup/archive job.

	9. A problem which caused MAC folders to be backed up/archived as
	   DOS folders has been fixed.

	10. DENY_NONE will be the standard file open method on servers.  
	    This means that some open files will still be able to be
	    backed up.

	11. Users will no longer be notified to close open files on backup.

	12. The correct stratification of ARCserve will work on NetWare 4.01
	    and SFT-III and 25 user for NetWare 3.12.

	13. A problem which caused the tape driver to overwrite the 
	    ARCserve screen has been fixed.

	14. You can now change the server name without having to reinstall
	    ARCserve.

	15. A third disk, called the NetWare System Files disk will have
	    all the Novell NLMs (CLIB, TSAs and SMDRs) and the user will
	    have the option to install these during the ARCserve Server
	    install.

	16. Networks with more than 128 network addresses (including the
	    internal network address of 386 servers) can now use the 
	    Workstation Database without getting an error.

        17. For Unattended and Attended Archiving, files and directories 
	    that have no owners or are owned by the server will have the 
	    correct dates and attributes.

	18. UNIX workstation host names will appear correctly in the job
	    form even if the HOSTS file has tabs or extra spaces.

	19. A workaround for a NetWare 3.12 CLIB problem, which caused
	    the server to abend when there were no jobs in the queue
	    has been added.

	Tape Driver
	===========

	1.  Support was added for the following tape drives:

		- IBM-HP 
		- IRWIN 2320
		- WangDAT Model 3100 (non-compression version of 3200)
		- Tandberg 4200
		- MicroDesign's LaserBank 1300D and LaserBank 2000D
 		- Tandberg IBM 4100
		- Tandberg 3600 
		- Exabyte 8500c
		- Exabyte IBM 8505
		- Archive Anaconda 2860
		- TEAC
		- CCG CY-8500
		- HP C1533A
		- Exabyte 2501 & Exabyte 4200

	   Drive support does not necessarily indicate drive has been
	   certified.  Please check current Certified Device List.

	2. A problem was fixed with the TEAC cassette tape drive, where
	   it reported no tape in the drive when there actually was a tape
	   in the drive.
	
	3. An abend might occur if Tapedrv.nlm was loaded with illegal
	   command line parameters.  It would occur when an illegal 
	   command line parameter was detected and tapedrv.nlm proceeded
           to unload itself.  This has been fixed.

	4. SCSI-2 Support was added to Tapedrv.nlm.   Tapedrv.nlm will
	   now be able to handle all SCSI-2 Tape drives correctly.

	6. Fixed occurences of unreleased resources caused when 
	   Tapedrv.nlm was unloaded.

	7. Fixed a problem that was found on the Exabyte 8200 tape drive
	   where ARCserve would report Tape Full (or Early Warning) when
	   it was trying to read the tape header.  This fix covers all
	   tape drives.




					Page 5

	8. Although the Exabyte 8500 tape drive is supported by ARCserve,
	   an OEM tape drive was reported by a user with the ID string 
           "EXABYTE EXB8500" instead of "EXABYTE EXB-8500".  Tapedrv.nlm was
           assuming the drive was an Exabyte 8200 tape drive.  The drive's ID
           string was entered into the driver so that the tape drive is now
           correctly supported as an Exabyte 8500.

	9. Fixed a problem with Quick File Access (QFA) Locate so that it
	   can now restore files on sessions which are larger that 4
	   gigabytes.  Before the fix, ARCserve would ask for a new tape
 	   because it couldn't find the target file.
						  	
	10. Fixed a timeout problem with Excel (Exabyte 2501) drives by
	    extending the timeout for the drive's Mode Select command 
	    (which takes a long time).

	11. Added support for IBM's new HP DAT drive which will only allow
	    data grade tapes to be used for backups. If the tape is found 
            not to be a data grade tape during backup, the tape driver will 
            return Write Protected and a network console message and an 
            ARCserve Log file entry will indicate the following:
 
	      "Error Writing to Non-Data Grade Tape."
	      "This tape may only be used for restore operations."

 	12. Fixed a problem with the Wangtek 51000ES Tape drive. The tape
	    drive would hang during a Read operation after a command to 
	    Space (Positions) to End-Of-Data was executed.  This problem
	    only occured during Attended Restore and did not occur during
	    an Unattended Restore.

	13. Fixed Compaq Tapebd driver so that it no longer requires a tape 
            in the tape drive during the loading of Tapebd.nlm or Tapedrv.nlm.

	14. A problem with the TEAC tape drive when used with some
	    SCSI boards (ex. BT-642)was fixed.  The TEAC cassette tape
	    drive does not report the correct inquiry data on the first
	    inquiry command.  Therefore, Tapedrv.nlm would not find the
	    drive and would report "No devices detected."

	15. A fix was made for the Wangtek 6200 DAT Rewind problem.  The 
	    tape drive would rewind very slowly if the tape was positioned
	    at End-Of-Tape (EOT) at the time of rewinding the tape.  The
            drive could take well over an hour to rewind at this speed.
            A fix was implemented to work around this problem.  

            If the drive's inquiry string reports the following,
    
             Wangtek 6200         
             Wangtek 6130-HS      with firmware 4W17
                                  
            the user must use the following loading sequence,

                     Load Tapedrv 6200

            The '6200' command line parameter will inform Tapedrv.nlm

					Page 6

            to use the workaround for the Rewind problem.  The reason we
            are using a command line parameter is that this fix is only 
            meant to be temporary until Wangtek fixes the problem.
   
	16. Tapedrv.nlm used to update the MAINT.LOG file to indicate tape
	    blank, even if the tapetest failed due to the fact that the tape
	    was write protected.  The MAINT.LOG will no longer be udated
	    for a write protected tape.

	17. A fix was made to Tapedrv's tapetest which would display 
	    "kbytes" written instead of "bytes" written.  The Byte Counter
            used to overflow itself on large tape tests and display 
	    negative bytes.

	18. Fixed MDI Tapebd interface to support their Unload and Delete
            Functions.  These functions were not properly supported in the
            earlier releases and an ABEND would occur if the SCSI Express 
            driver was unloaded before ARCserve and Tapedrv were unloaded.

	19. A bug was fixed in Tapedrv.nlm where the software was recognizing
	    an Exabyte 8200 as an Exabyte 8205c tape drive.  

	20. Fixed an Early Warning (EW) detection problem that could occur on 
            some tape drives.  The error showed up during a FULL Tape Test 
            when after it had filled up the tape, and began the test for 
            detection of EW, the software would report a EW Test failure.  

	21. The WangDAT 3200 was supported and certified, but the string
	    was not being recognized properly.  We now tag on two types
	    of strings,
                WangDAT MODEL 3200      (current)
                WangDAT Model 3200      (new)

	22. A change was made to increase the tape positioning speed for
            the Tandberg line of tape drives.

	23. A fix was made to our Quick File Access (QFA) Logic to enable
	    QFA restores of a file that was in a massively humongous session.
	    On some tape drives, the problem might manifest itself as a
            constant clicking noise.  The problem is fixed.

	24. The block size for the Exabyte 4200 and 4200c drive was 
	    changed from 1024 to 512 bytes.  Since the drive was not 
	    certified at the time this change was made, it should not
	    affect many customers.  If there are clients who were using
	    the drive at the 1024 block size, they can load tapedrv 
	    with the following command line,

                Load tapedrv block=0

            Or re-do all their tapes.

	25. Under NetWare 4.01, unreleased resources were reported when
	    Tapedrv.nlm was unloaded.  The problem has been fixed.

 	26. Compression can be enabled/disabled through the tape drive
	    console screen for compression drives.

 	27. ARCserve 4.02 has added the capability to perform a short
	    tape erase.  The short tape erase just erases the tape header.
