A question for the ReFS guru's. Do spaceless GFS restore points on REFS "grow" over time? I'm referring to the actual disk usage, not the size as reported by the file system.
I understand that at the time of creation, they are comprised of pointers to blocks in the associated backup chain, so effectively take up zero, or close to zero space. But what happens as the associated backup chain cycles through its retention period, and blocks with a pointer to the spaceless GFS are removed from the backup chain?
To put it another way, lets say the GFS has a pointer to block "X" in the backup chain. The GFS consumes no space for that particular block. Over time block "X" is removed from the backup chain as it cycles through its retention period. Does that block then become associated with the GFS restore point; the GFS now consumes some disk space? And would it be a reasonable assumption that this GFS would continue to grow, the longer it was kept.
Am I thinking about this correctly?
I've gone over the animations showing the ReFS fast clone, but couldn't find one that illustrated this scenario.
Many thanks in advance.
