Expired NBU images
Hello,
Could you answer a question?
How can I control the prioritization of images so that they are not removed or expired on an advanced disk that has reached its capacity?
Using Data Classification or modifying retention level?
I suggest that you read up in Admin Guide I in the SLP section.
As sdo says - you obviously need to have a 2nd STU where images are duplicated to.
I see this in 8.2 Admin Guide I:
Staging using the Storage Lifecycle Policies utility
Staged backups that are configured within the Storage Lifecycle Policies utility also
consist of two stages. Data on the staging storage unit is copied to a final destination.
However, the data is not copied per a specific schedule. Instead, the administrator can
configure the data to remain on the storage unit until either a fixed retention period is
met, or until the disk needs additional space, or until the data is duplicated to the final
location.
No BasicDisk or disk staging storage unit can be used in an SLP.
See “About storage lifecycle policies” on page 645.Even for basic disk with DSSU, the images need to be duplicated to alternate storage before disk cleanup can take place prior to expiration date.
