A year ago I set up Ubuntu server with 3 ZFS pools on my server, normally I don’t make copies of very large files but today I was making a copy of a ~30GB directory and I saw in rsync that the transfer doesn’t exceed 3mb/s (cp is also very slow).
What is the best file system that “just works”? I’m thinking of migrating everything to ext4
EDIT: I really like the automatic pool recovery feature in ZFS, has saved me from 1 hard drive failure so far
Where are you copying to / from?
Duplicating a folder on the same NAS on the same filesystem? Or copying over the network?
For example, some devices have a really fast file transfer until a buffer files up and then it crawls.
Rsync might not be the correct tool either if you’re duplicating everything to an empty destination…?
