Reading up on (and trying to work with) DPM 2016 nowdays so here’s some links to myself before I close them from the browser:
- How does DPM work? Very briefly, and skipping over the details:
- There’s a protected server – the thing you want to protect.
- DPM creates a replica of the protected server. This replica is a copy of the data on this protected server.
- Replicas are stored in storage pools (a set of disks on the DPM server).
- Replicas sync with the source.
- In the case of file data backups, an agent on each protected server tracks changes and transfers these to the replica.
- In the case of application backups (e.g. SQL, Exchange) an incremental backup is taken however the application requires such backups to be taken.
- Quick shoutout to the difference between application and file data.
- There’s also express full backups. A snapshot of the replica is taken and the replica is updated with the changed blocks.
- At regular intervals DPM creates a recovery point – this is a version of the data from which data can be recovered.
- How to increase DPM 2016 replica when using Modern Backup Storage (MBS)
- Modifying replica size with PowerShell – can’t do this via UI (as you could with previous version) so PowerShell is your friend
- Introducing DPM 2016 Modern Backup Storage (MBS) – some good videos. Short and useful.
- How to reduce DPM 2016 storage consumption by enabling deduplication on Modern Backup Storage – ReFS doesn’t support dedup; MBS makes use of ReFS; the blog post is about getting dedup enabled with MBS. Why do something that is unsupported, I don’t know. But it’s good info.
- How to perform a manual initial replica on DPM Modern Backup Storage (MBS) – good info, especially this little part which I’d like to quote here for quick reference:
Copy the path and save it in a notepad. It’ll look like the following. E:\ on DPM2016TP5-01.contoso.local C:\Program Files\Microsoft System Center 2016\DPM\DPM\Volumes\Replica\31d8e7d7-8aff-4d54-9a45-a2425986e24c\d6b82768-738a-4f4e-b878-bc34afe189ea\Full\E-Vol\
The first part of the copied string is the source. The second part, separated by a whitespace, is the destination. The destination contains the following information:
DPM Install Folder C:\Program Files\[..]\DPM\Volumes\Replica\
Physical ReplicaID 31d8e7d7-8aff-4d54-9a45-a2425986e24c\
