Differential backup schedule

Question

Hi All,

I want to change the backup schedule for windows failover cluster hyper V virtual machines from daily full backup to (Friday full and rest of the days in the week as differential).

i have created a schedule which is as follows:

Friday-full

Saturday-1

Sunday-1

Monday-1

Tuesday-1

Wednesday-1

Thursday-1

Friday-full

Saturday-1

Sunday-1

Monday-1

Tuesday-1

Wednesday-1

Thursday-1

I configure the client in the networker and apply the above schedule but i have observed that the backup time and size for differential backup is same. Is there any further configuration required or am i missing something ?

Does NW always convert backup onto full?  As in such case, as this is cluster, I would suspect config might not have been done well and data is saved under wrong index name (which you can enforce with save -c ).

Hyper-V incremental backups are only supported starting in NMM 9.x. Please refer to:

NetWorker Module for Microsoft for Hyper-V VSS Release 9.1 User Guide

https://support.emc.com/docu81466_NetWorker_Module_for_Microsoft_for_Hyper-V_VSS_Release_9.1_User_Guide.pdf?language=en_US

Note: It would be helpful to provide environmental information, such as the NMM , NetWorker, and Hyper-V versions? Also include o/s and version. As demonstrated in this question, the answer does depend on what version you are using.

Hope this helps... Cheers.

Hi Wallace, Following is the required information: 1- Networker version: 8.2.2.2 Build 946 2- NMM: 8.2.2 3- Hyper-V: 6.3.9600.16384 4- Failover Cluster OS: Windows Server 2012 R2

Thanks for the information...

Since you are using NMM 8.2.x, then you can only perform level=full backups for hyper-v

Perform hyper-v incremental backups, you will need to upgrade your NetWorker server and client software, as well as nmm, to minimum 9.x
