Well for DLO 7.5 Dedup info.


for DLO 7.5 Dedup info. already answered

 and all the details you can find in the DL 7.5 Admin guide, follow as per admin guide


Hope it helps

Hi, Thanks for the response.


Thanks for the response. The admin guide is not giving any information on Multisite installation. Since i am planning to install this in Multi Site with Central Administration, i am looking for specific information about that.

How can I get a model installation details of the following topology? Can someone make one model implementation by taking Data Center, Head Quater and Branch Offices into consideration?

To arrive at a deployment topology, the following factors must be considered:
1. Total number of sites (Data Centers, Head Quarters, Branch Offices, etc.)
2. Total number of end-points in each site and physical location of the Agents in relation to the servers
3. Connectivity of the end-points (LAN, WAN, Link Speed, etc.)

Hi, We are facing problem


We are facing problem while planning implementation of DLO 7.5. Admin guide dont have details of all tge topologies as its just good for single site installation. Please provide architectural documents ASAP as we already bought licenses but still not using. Thanks.

    2.The agents need to be upgraded by push install. It will not be liveupdated.


    There are 3 ways of upgrading Symantec DLO 7.0 agents to Symantec DLO 7.5 agents:

    1. SMS or Log on Script Method

    2. Manual Pull installation by accessing Symantec DLO Administration Server’s agent share

    3. Push installation from Administration Console

    DLOCommandu.exe now provides an option to print the list of existing agents which helps in creating the list of users in a .txt file which can be used for pushing multiple agents via Push Agents from Administration Console UI

    Eg: C:\Program Files\Symantec DLO>DLOCommandu.exe -ListMachines > AgentList.txtThe above Command Line Option would print the list of existing agents to the text file AgentList.txt which can be imported during agent push install from DLO Console UI

    Option 3 is recommended as it provides automated upgrade of multiple agents

    Does DLO 7.5 allow me to create a dedupe server as oppossed to just adding one? I get an error when adding one that says "The Server Host or port details you have entered is invalid or there is no dedupe server running at the specified location" - is there a windows 2008R2 feature or role I need to install?
