We've set ours at 25%.  We are just piloting an all disk backup pool for
some clients on one of our servers and for small files on another.

So, how high do you set your file class reclaim percentage?  If its that
fast you should be able to cope with 20% free or less before reclaim.

Dito and that is how we implemented large disk backup solutions on ATA disk.
We use File device classes.  We have found that the reclaim extremely fast,
much faster than tape.

You can run reclamation with D2D by using Devicetype=file on disk.

There are some other faster restore solutions out there. With Virtual
Tape Libraries you get all the speed and reliability of D2D but with all
the functionality of tape. For example, I happen to work for a company
that provides a VTL solution which is certified by IBM-TSM. There is no
way to run reclamation on D2D so that must be done once it is
transferred to real tape. With a VTL solution, you backup to a virtual
tape library and device, run the reclamation on that, which is nearly
instantaneous and then copy to real tape via archive and that saves you
hrs and hrs of reclamation time. The other benefit is the near
unlimited amount of mount points. With backups and restores, the speed
of real tape and libraries are not longer your bottleneck.
