Best partition settings for repo on local disc drives

[robertoszym]

Hello All,
I need to configure local partition for Veeam repo. I have 160TB on raid5 for it. Whats are Your suggestions for alocation unit size, 64kB?
What repo setup is optimal? Is one file per VM good option + windows level deduplication? I like to backup whole cluster in one job so files with full will have around 4 -8TB in "clasic" mode.
I think I can afford to not enabling Windows dedup.

Format it with ReFS 64KB and select for the hardware raid a bigger stripe size. We usually write with block sizes of 300-600KB. So use at least 256KB blocks on the storage.
Then use the default Veeam settings for deduplication (enabled), compression (optimal) and Block size (local).
As usual do not bring more than 10 disks together in a raid set. Use Raid 50 with 8+1 or 6+1.

I would not recommend to enable windows deduplication as it will reduce performance.
