ZFS cache pool or btrfs

[DGB]

I'm redoing my cache drives and splitting them up, I,e vms, dockers and downloads. 

 

Would it be better to move to ZFS over btrfs? 

Each pool would be a single drive (ssd or nvme)  

 

Would they benefit from snapshots For backups?

 

Thanks

ZFS is better, but it's also a RC implementation in unraid, so at this point, you may run into caveats still showing up in RC threads. Specifically, zfs can do raidz levels reliably as compared to btrfs. Also has better bitrot protection

Snapshots only help with fat finger scenarios, they are not true backups at hardware level. If you lose your pool, snapshots go with it. But, yes, they can help with certain human mistakes

Thanks for the reply, 

 

I didn't realise the snapshots had to be kept on the same pool and thought I'd back up to the original array.

With both btrfs and zfs you can send/receive snapshots to a different disk/pool of the same filesystem on the same or to a different server as a backup,

So I could have another pool with a spinning a spinning disk in the same file format btrfs or ZFS and send snapshots to it but can't to the array?

I mentioned disk or pool, as long as it's the same file system it can be used as target for send/receive.

I would really love to hear more opinions on this, just watched @SpaceInvaderOne's video on how to easily reformat the cache pool. Been using BTRFS for a while.
