From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to transfer a lot of storage? (lemmy.world)

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.

Yes, using rsync between the two servers would be the best option. I guess, despite I already have the drives. On my end I could provide the access and arrange proper security with VPN, but at the target there are still too many question marks and I cannot currently count on some basic Linux knowledge there.

For a previous transfer of much less data I had to write a PS script that handled the transfer. It was very slow.

So, I am actually dealing with another problem: Can I get enough information from the non-tech persons to provide the best and easiest solution for them.

Thx so far all the ideas from all of you.
