No way to rebalance by file size?

Question

I use a lot of NTFS hardlinks and besides, want to relegate the bigger files (as they tend to be either backups or replaceable media) to a different, slower underlying disk/volume. Segregating by a file size threshold is a workaround, though not possible to prune the offloaded entries without ROBOCOPY /PURGE'ing from the main volume, which has symlinks to them. I'd imagined Drivepool could do this better with a union filesystem, compared to a mix of scheduled Robocopy tasks for moving data to the offload volume(s) and cleaning orphaned entries. But there is no balancing rule shown for size or attributes, just the naming pattern. Can Drivepool automatically rebalance by other properties than filename mask?

Correct, no we don't support that. 

Unfortunately, getting most anything but the filename is a LOT more expensive in terms of system resources.  And since a LOT of this code needs to run in the kernel, any extra will add up exponentially. 

 

However, you could do by extension, as that can be a good indicator of range of the file size.
