Not sure it matters, because with out cache I get write speeds > 100MB on gigabit anyhow, but most of the cache info I see talks about how if you use cache, and it dies before moving to the storage array, then you lose the data.

 

Cache drives are now done as BTRFS pools of Raid 1 now correct?  That seems to be what I see/read.  So if I put 2 240GB ssds in the cache together, then I have a 240GB Raid 1, so if an SSD dies, then you don't lose any data with a single drive failure.  Is this correct?

 

Side question, haven't looked much, but is there a way to backup your cache drives (dockers and vms) to the Array on a schedule?

Correct. Default for a cache pool is raid 1 and is fault tolerant.

Backing up of your appdata to the array is handled by the CA backup/restore plugin probably already installed. If not installed you can find it within the apps tab.

Backups of your VM's can be handled by the auto backup VM script
