I have nothing as large as 190TB... That said, here's my experience, to help you decide if you want to look more into it...
I have built a FreeNAS system for my home NAS/backup needs. It is currently composed of 5 x 3TB disks, running in RAID-Z2. I run my dirvish installation in a FreeBSD Jail. I have been running this system for nearly a year, and I have to say that I am very impressed with the FreeBSD / ZFS combination for this application. It is extremely performant, and rock solid. Also, an important side-benefit... ZFS offers on the fly compression. So, if your backups contain a lot files that are compressible, you'll be able to save a lot of disk space, with little performance impact (if you use an appropriate CPU). If you have a large backup need, you can also create multiple ZFS Pools, and distribute your backup vaults across pools. Extremely flexible. http://www.freenas.org/ — Patrick Toal pt...@takeflight.ca > On Oct 8, 2015, at 3:31 AM, Andreas Nitsche <a...@sixhop.net> wrote: > > Hi Chris, > > maybe you want to think about having more banks with smaller partitions > in case of a filesystem check or even a resize.
