Re: TDP for VE; CBT backup size versus OS modified file size
Hi Stefan, Thanks for the tip. We indeed didn't exclude the swap file. We will improve our configuration. But for the comparison it was included in listing the modified files as in the backup made. If the entire file was changed, we expect that the modified files and the backup were the same size, but the backup is much bigger.

Regarding this statement, when you open, edit and save an office file (for example) it rewrites the entire thing to disk, even if you edit or add a single line (so I was told). This is the case with most edits I believe except for databases and maybe some other exceptions that don't open all corresponding data and rewrite the whole thing to disk when you save.

TDP for VE clientschedules
Hi all, We have a VMware vSphere environment with 246 virtual machines. We have 4 datamovers to do backups with TDP for VE. In the client schedule we define the command: -vmfulltype=vstor -vmbackuptype=fullvm -asnodename=nodename that owns the backupdata -domain.vmfull=VM=list with virtual machines, comma separated -MODE=IFIncremental This command is limited to 512 characters. So, it isn't possible to schedule all virtual machines at one timestamp, because the hostnames of the virtual machines don't fit in 4 times 512 characters. We could make more schedules for the 4 datamovers, but there would be a risk that client schedules are missed, if a client schedule starts while another one on the same datamover is still running. Does anyone have an easy idea for scheduling 246 virtual machines with TDP for VE?

File systems allow you to smile and answer the auditor's question about what tape the data is on and say, What is this tape you speak of? The one that is better is the one that you build your system to use. I believe I could successfully argue either way. I have systems working both ways and I tend to prefer file system, but most of my Ethernet networks will not handle file system so I use mostly VTL.

What you can do with TSM 6.3, is set up node replication. Let the dying server replicate its data to the target server, and when it is in sync, break the replication and shut the dying server down. That's probably less work for you, but still won't happen quickly. Or if this is about server consolidation, you could just set up 2 instances on the target machine, without needing to get all the metadata in one DB. Can you tell us why you are doing this?

Re: Tapedrive 3592 E06 speed of 160MB/sec
Hi Andy, There are no links slower than 1Gb. For TSM there are 2 links used, each have the 2,5 Gb.

Is the DWDM aggregating multiple links to the get the 2.5GB? If it is your data may only be flowing down 1 link at whatever speed that link is running. Also, I think a 2Gb/sec connection is closer to 200MB/sec.

On both sides we use TSM servers and 3592 tapedrives. We use SAN and DWDM between the two locations. Writing data from a TSM server to a tapelibrary that are on the same location have the speed according the technical specifications. A TSM server writing to the other location has not half of the speed. For example: On one side we have 3592 E06 tapedrives, that can write with a speed of 160MB/sec, when the TSM server is on the same location. There is 1 SAN switch between the server and tapelibrary. A TSM server on the other location, that is also connected with that library, get a speed of 60MB/sec. There is a SAN switch and a DWDM switch on one location and also a DWDM switch and a SAN switch on the other location between the server and tapelibrary. The speed of the HBA's in the TSM servers is 2Gb/sec, the speed of the ports on the SAN switches are 2 Gb/sec and 4 Gb/sec and the speed of the DWDM swiches is 2,5 Gb/sec. 2Gb/sec is about 320MB/sec. So the bottleneck is should be 320MB/sec. When there is no other traffic on this network, the speed should be more than 60MB/sec. The speed is of the tests is determined of data of the summary table of the TSM datebase. Can some explain why the speed is very slow? (only 60MB/sec instead of 160MB/sec). Does anyone know how one can determine the speed of DWDM switches?

Move data from a copy storage pool to another copy storage pool
Hi all, To move data from a primary storage pool to another primary storage pool, you can use the command 'move nodedata'. But how can you move data from a copy storage pool to another copy storage pool? I have to move data from 3590 tapes to 3592 tapes. I know I can delete volumes from the copy storage pool and make a backup of the primary storage pool again. But I prefer a saver way. With regards, Ruud Meuleman
