We are low on space. As we look through old jobs, or anything that is still being held on past our retention period. We have plenty of infinite and long term retained items mixed with our regular data in our primary DDB.
I’m claiming that the infinite retention or long-term jobs could be hodling reference blocks. This is the reason why we see data size on disk being a reasonable number but the library being full. For example, 800 TB size on disk but the 1.5PB library is full.
as we go through jobs, some are seen as not “big fish” because data written may show for example 85GB written for a 1.5TB App size server. We skip and don’t worry about this because, I’m told well 85 GB is only what will come back in space. Let's look for 1TB + being written.
I’m thinking that even as we size our future library, we should consider a pool of space that will always sit there and hodl these reference blocks and be “unuseable” space.
Hopefully this rant makes sense?
