RE: DPM disk usage.

[Tobie Fysh]

My understanding is that it only stores the block changes so I guess that's 
about right

Subject: DPM disk usage.


I am using DPM on a fileserver for backups. This is the off time for school, so 
the data is very stable right now, very few changes. The data belongs to 
students and teachers and they are all off. I just moved everything over this 
summer and I have a months worth of recovery points using 197 GB's of space. 
The data is 207 GB total.

Is DPM really that efficient with disk space usage?

Re: DPM disk usage.

[Crawford, Scott]

Yup. Each recovery point is only storing the *blocks* that have changed since 
the last recovery point. So, if you have a relatively static source, the 
recovery points can be quite small.
