Re: Any way to avoid full backup of data relocated on TSM client file system??
Steve, Yes that is an option but also would have consequences in a restore/recovery situation. The clusters are where the company's user home and group directories live, hence permissions are somewhat granular to say the least. In a recovery situation they would be lost or at a minimum restored incorrectly which would lead to the all too frequent scenario of blaming the backup architect. Probably the most I can do at this point is to continue making sure that they are aware of the resulting cost when these changes are made. Then they can decide if they want to pay the bill or push back on the planned changes, which is usually fruitless as the person or department making the changes will hide behind the claim that it needs to be done for compliance. I just wanted to make sure there wasn't some way to deal with it that I may have been overlooking.

Re: Any way to avoid full backup of data relocated on TSM client file system??
Have they considered the use of groups? Once the group has access they can add or remove users as needed. I understand that the home directories will have the user instead of a group, but anything that affects the whole tree or a large part should be a group. One thing we have done in the past is cross training, if possible cross train a security admin in the ways of backups. If they have to live with the pain they might see the error of their ways. The reverse is also true. Something to consider, skip NTFS permissions except 1 day per week.

Have enough space in your storage pool to keep the whole day's log backups if restore time is an issue.

TSM 6.2 Deduplication Question
I'm reviewing the features of 6.2 and trying to decide if its worth the new-version-risk for one of our smaller branches. We are a 5.5 shop, so I'm a little behind on the details of the new features. The manual says that deduplication is available only on storage pools using a File device class. (many times!) However, I noticed this other entry under Virtual Volumes: When you copy or move data from a deduplicated storage pool to a non-deduplicated storage pool that uses virtual volumes, the data is reconstructed. When you copy or move data to a deduplicated storage pool that uses virtual volumes the data is deduplicated. http://publib.boulder.ibm.com/infocenter/tsminfo/v6r2/index.jsp?topic=/com.ibm.itsm.srv.doc/t_network_virtualvol.html From that, I am inferring you can use a device class of server as well. This would be a huge for us if this were true. Can anyone confirm or deny this? Is this just a documentation hiccup?
