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.

What is the largest file transfer you have ever done? (startrek.website)

I'm writing a program that wraps around dd to try and warn you if you are doing anything stupid. I have thus been giving the man page a good read. While doing this, I noticed that dd supported all the way up to Quettabytes, a unit orders of magnitude larger than all the data on the entire internet.

This has caused me to wonder what the largest storage operation you guys have done. I've taken a couple images of hard drives that were a single terabyte large, but I was wondering if the sysadmins among you have had to do something with e.g a giant RAID 10 array.

Upgraded a NAS for the office. It was reaching capacity, so we replaced it. Transfer was maybe 30 TB. Just used rsync. That local transfer was relatively fast. What took longer was for the NAS to replicate itself with its mirror located in a DC on the other side of the country.

Yeah it's kind of wild how fast (and stable) rsync is, especially when you grew up with the extremely temperamental Windows copying thing, which I've seen fuck up a 50mb transfer before.

The biggest one I've done in one shot with rsync was only about 1tb, but I was braced for it to take half a day and cause all sorts of trouble. But no, it just sent it across perfectly first time, way faster than I was expecting.

Never dealt with windows. rsync just makes sense. I especially like that its idempotent, so I can just run it twice or three times and it'll be near instant on the subsequent run.

Yeah, shout out for rsync also. It's awesome. Combine it with ssh & it feels pretty secure too.
