I'm running out of space.

We are in the middle of a massive migration to PVE. It's overloading my backup servers. Space requirements are exploding.
It's weird. We can migrate a dozen VMs and not see much increase, and then BAMM we are up by a terrabyte.

I know what it is. Lotta databases, whole lotta delta, and a lotta uncompressible data. Right? I mean, that's always what it is.

Do you think i'd get much dedup advantage from segregating Win and Lin backups into different PBS servers?
 
I use a 2-tier structure.

SSD baremetal backup server with limited storage (this does the backups) is getting
11.9 dedupe factor with a retention of 2 days.
That's 6.5TB of data. I'm out of room and can't cut retention farther.

Virtual backup server running on the NAS with huge storage (backups are synced here) is getting
14.4 dedupe factor with a retention of 6 days.
That's 10TB of data. And its growing to eat the whole NAS.

I'm going to need a new primary to handle some of this.
I think I'll restrict the new one to the big linux database backups.
It will get a lot of that incompressible constant delta stuff,
... and hopefully some dedupe advantage from being restricted by role and OS family.

Dunno. I have to try something. It don't fit where its at.
