Re: DISASTER Client Restores Slow
Two thought on your comments. First: If restores are taking a long time due to the amount of data being restored, you could look at HSM. If your target client is a Windows 2000 machine look at OTG DiskXtender. These products will move files, based on criteria such as age, size, and/or file type, to tape and replace them with a very small tag on disk. When you recover your client only the tags are restored. This provides significant performance to recovery. Second: With the size of today's disks, recovery using tape is simply a task that requires time. An option is to use remote disk storage. Having a real time or almost real time set of remote disks makes recovery of even the largest sites a few hour task.

Performance again!!!
A comment about performance being 9 minutes to tape and 75 seconds to disk. Is it possible that most of the 9 minutes was tape mount and positioning time? Please respond to ADSM: Dist Stor Manager [EMAIL PROTECTED] Sent by:ADSM: Dist Stor Manager [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject:Performance again!!! Hello everybody, It seems like TSM performance problems will neer end!!! Here is the new problem: The customer is running TSM 4.2.1.0 on a Windows 2000 server machine . An IBM rack case 82XX which contains a Quantum DLT8000 tape drive is connected to the server. The driver version for the Quantum DLT drive is 1.5 and is installed on the W2K machine. We tried a backup of 350MB on the local server with the Windows 2000 Backup utility and it took us approximately 75 seconds . Next , we tried the same Backup from TSM using its Device Driver and it took us about 9 minutes . We tried switching TSM to use the Native device driver but still we got the same performance result . So we upgraded to 4.2.2 ; In the Device Manager for TSM,we can see that TSMSCSI.exe is upgraded to 4.2.2.25 and the ADSMSCSI.sys is 4.2.2.3 . The server has a version of 4.2.2.25 . Still , we obtained poor backup performance . We suspected that maybe it was a database bottleneck ( eventhough it is still empty) ; so we tried the same Backup using TSM but the destination was on the HardDisk. The performance was good and the backup finished within 75seconds . So, we can eliminate the database problem. Also, we noticed with version 4.2.2.0 that it is crashing frequently . It was exiting abnormally . On the site of tivoli, the latest version of TSM server is 4.2.2 . We do not have the 5.1 release . does anyone have a suggestion? thx a lot Sandra __ Do You Yahoo!?

Re: Outlook PST files
We also have this problem. One other idea you didn't mention is to purchase an email migration tool. EmailXtender by OTG is one product which will do this. With this product the outlook users can move there PST (personal store) data back into the exchange server and the PST's can be deleted. You might think this will just move the problem. EmailXtender helps by migrating old exchange items to TSM and replacing them with a 1K tag. The exchange backups only backup the tag. We have not tried the product so can not recommend. The information provided is a quick summary of there marketing material. We will be looking into the product at a later time.

For my Wan clients I have implemented Adaptive subfile differencing but still running marathon backups of some these clients. So given that pst files dramatically impact WAN (and to some degree LAN) backups, how can I address this? * Don't backup .pst? (Most likely not an option) * Force .pst archive rule * reduce frequency of .pst updates (e.g., limit to 1/week; wishful thinking would be this would occur on Fri so that large backups would occur on weekend) * reduce size of .pst by creating new pst files every so often * Storing .pst files centrally rather than locally. * Other - thoughts, anyone?

Re: NT server migration to Win2000 server.
-Original Message- From: Zosimo Noriega (ADNOC IST) [mailto:[EMAIL PROTECTED]] Sent: Sunday, March 11, 2001 4:46 AM To: [EMAIL PROTECTED] Subject: NT server migration to Win2000 server. Hi All! We're planning to migrate all NT4 servers to Win2000 servers that Adsm environment will be affected because the Adsm server (version 3.1.2.40) and client version 3 are installed on NT4. I'm confused regarding the Adsm version that is compatible to win2000 servers. Do you think i need to upgrade to TSM or use this existing Adsm version? Your help are really appreciated. Thanks, Zosi
NT Restore Question?
We have many different hardware configurations running Windows NT and Windows 2000. We are not having any problems with the backups. If we have a server failure, can we setup new hardware which is different than the hardware we used to make the ADSM backups and restore successfully? We would ensure that we matched the new hardware to the old in regard to a single processor (kernel) and a multi-processor (kernel).

Novell Server Specific Information Statistics?
We have 5 Novell 4.1 servers which we backup nightly. In the dsm.opt file I have a domain statement as follows: "DOMAIN NDS". I also have tried "DOMAIN Server Specific Information", "DOMAIN ALL-LOCAL", and "DOMAIN NDS ALL-LOCAL". None of these give me statistics for server specific information. All volumes and the NDS from the master and replica's backup with statistics in the last backup start date/time, days since last backup started, last backup completion date/time, and days since last backup completed fields. The Server Specific Information has blanks in these fields. Does anyone know why? Lee Fletcher Network Project Integrator AmerenUE Callaway Plant [EMAIL PROTECTED] 573-676-4106
DSMADMC from Visual Basic Shell Function?
I'm attempting to write a VB application to monitor the daily ADSM schedule
and to issue several commands throughout the day. My problem is that when I
use the shell command nothing seems to be working. I do not get any errors
but I do not get any output either. The format of the shell command I'm
using is provided below. I have not set any environment variables and plan
on executing the VB application under Windows 2000.
The following should issue the "q fi".
Private Sub Command1_Click()
x = Shell("C:\Progra~1\IBM\ADSM\saclient\DSMADMC.EXE -id=admin -pa=x
-outfile=c:\cmdout.txt q fi")
End Sub
The function runs without error but I do not get the -outfile allocated.
Thanks in advance for any input to my problem!
