I want to transfer 80 TB of data to another locatio . I already have the drives for it. The idea is to copy everything to it, fly it to the target and use or copy the data on/to the server.
What filesystem would you use and would you use a raid configuration? Currently I lean towards 8 single disk filesystems on the 10 TB drives with ext4, because it is simple. I considered ZFS because of the possiblity to scrub at the target destination and/or pool all drives. But ZFS may not be available at the target.
There is btrfs which should be available everywhere because it is in mainline linux and ZFS is not. But from my knowledge btrfs would require lvm to pool disks together like zfs can do natively.
Pooling the drives would also be a problem if one disk gets lost during transit. If I have everything on 8 single disks at least the remaining data can be used at the target and they only have to wait for the missing data.
I like to read about your opinions or practical experience with similar challanges.
It’s a good idea to use what you know. I don’t have much experience with btrfs but if it does what it says on the tin then it should be safe to use.
Copying the contents at the target is a good strategy. If the drives are to be put into 27/7 use later I would probably consider wiping them and run an integrity test before putting them to use, as once they start being used it will be too late (and stay as a doubt in the back of my mind).
