Hello Expert,
Need advice from you experts on my current DP setup.
I am using Dp 7.01 with cell manager on windows 2008 R2 64bit. All the clients in the enviornments are winodws only and total clients we have is around 30. During this year auditing the auditor has raised the concerned for backup data encryption. Currently I am using MSL2024 with ultrium 3 drive at production site and standalone tape drive with ultrium 3 on DR site.
Now as per auditor I need to encrypt my backup data. I belive I have 2 options here
1. Drive based encryption
2. Software based encryption
My concerned over here is what are the limitations of drive based encryption and software based encryption. I hears there are performance issue in software based encryption so I don't want to go for that. Hence my option will be drive based encryption only.
Can anyone suggest what are the limitations of drive based encryption? Also I need to upgrade the ultrium 3 to minimum of ultrium 4 to use drive based encryption. Do I need to upgrade this drive to both site production and DR as I am restoring my production backup at DR regularly for testing.
Also if I take increment backup can I be able to restore it at DR since at DR I have standalone tape drive?
Please excuse me if I am not very clear.
Many thanksfor any help in advance.
Regards,
