Microsoft data protection manager best practices

A library client is a computer on which DPM is installed, the library-sharing command has been run, and the medium changer is not enabled. We recommend that the system configuration of the library server computer and all library client computers be as similar as possible, and that you do not configure any protection groups on the library server. For example, they should all use a local instance of the DPM database or all of them should use a remote instance.

You cannot have some DPM servers using local instance and others using a remote instance. After you've set up tapes, when you create a protection group including data sources you want to protect, you'll be able to select tape for long-term and short-term data storage. On the computer that will be the library server for the shared library, use Device Manager to enable the medium changer. Then restart the SQL service. To configure the DPM servers to use a shared library, on each library client computer, open an elevated Command Prompt window, and then run the following commands:.

On the library server computer, open an elevated Command Prompt window, and then run the following commands one time for each library client. For example, if your library server supports three library clients, you must run this command three times on the library server.

Also, ensure the domain account is a member of the local Administrator group on all computers that share the library. Then, on each library client computer, open an elevated Command Prompt window and run the following commands.

Then perform a rescan or refresh on each of the library client computers. The quickest way to see all media on all of the DPM servers is to perform a rescan on each, followed by a detailed inventory.

Next, on any one of the servers, mark a number of media as free, and then perform a refresh on the other servers. After you've configured library sharing, you can use the shared tape library as if it were attached to each DPM server. After planning your storage, if you are considering tape storage, see the article, Identify compatible tape libraries.

We recommend that you schedule the short-term protection backup to run a day before the long-term backup. That way you can be sure you're using the latest short-term backup in order to create the long-term backup.

You'll need to remove the sources from a protection group and expire the recovery points, or modify the protection group settings to clear tape protection. To expiry a tape, you mark it as free and then unmark it and recatalog. It's useful for data that has a low RPO and thus needs to be recovered quickly after failure. A dedicated disk for the startup, system, and DPM installation files; and one dedicated to the storage pool. DPM does not add any disks containing startup files, system files, or any component of the DPM installation to the storage pool.

To prepare disks, DPM reformats the disks and erases any data. Microsoft strongly recommends you use GPT disks. Don't mix devices in a single zone. EISA partitions must be removed from disks before you can add the disk to the storage pool. For more information, see Deduplicate DPM storage. The following diagram provides an overview of DPM backup functionality. Learn more in How does DPM work? Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.

So can I said that if I keep to one protection group is also possible and there won't have any impact to ADs as I assumed the ADs replication will be stopped during backup at the same time.

If I wish to separate to two groups, do I merely uncheck the boxes drives of AD1 or do I need to stop protection? I am getting a bit confused with how DPM works. On-prem AD backup to Azure Backup. Question about Active Directory backups.
