While we recognize that this is a valid requirement, it has not been a high enough priority considered along with the other work we have been doing. We do not feel that this will become a high enough priority that it will be resolved in the next two years, so we are closing this for now. Thanks for your interest.
what you are saying is that a snapdiff backup is not a valid backup? only a monthly full is?
I think it would be better/safer to:
For "Include/exclude changes", "delete backup" or "policy changes" to force a create new base eg delete the TSM created snapshot.
eg
* TSM snapshot A exists
* incremental snapdiff starts
* TSM detects one of the above conditions
* TSM removes snapshot A
* This forces TSM to create a new base
* TSM creates snapshot B
* Uses snapshot B as the new base.
For "File skipped" or "file excluded for file set" Delete the newer TSM snapshot, rather than the older one so that the problem can be corrected and the files backed up on next run. eg
* TSM snapshot A exists
* incremental snapdiff starts
* TSM snapshot B is created
* TSM attempts to backup differences between A and B
* Has to skip a file
* TSM reports the issue, but deletes the snapshot B
* operators fixes issue
* incremental snapdiff starts
* TSM snapshot C is created
* TSM attempts to backup differences between A and C
* Succeeds
* TSM deletes snapshot A
This will mean there will be no opportunity for data loss.
Thank you for submitting this enhancement request, the logic behind this behavior is explained in the following tech document: https://www-304.ibm.com/support/docview.wss?uid=swg21501576
if you feel that this RFE is still valid please provide some more information about the specific use case , what are you trying to achieve and why?
all other types of backups do this but not snapdiff.
