DPM as a statistics tool

image Remember old days of DPM 2007 RTM? I don’t know about others but I myself was used to use it more in OpsMgr fashion. No, really, Data Protection Manager was great monitoring tool back there: as soon as something had happened with, say, your Exchange server or SQL, the backups just stopped working. It is not that way now (I guess it is rather good =) ). But still we are able to use DPM in some tasks not related actually to the data protection itself.

What I am asked for quite often as a DPM person is… to calculate how much data on a server changes. Yes, we may get approximate figures from the corresponding Recovery point volume size. For example: if we have a DB, which uses 3000GB on the recovery point volume and retention period is, say, 30 days, then the change rate may be approximated as 3000GB/(30days*24hours) ~ 4GB/Hour. Of course it doesn’t tell us the peak values. Of course it is only approximation, but sometimes it is enough.
