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.

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.

I worked at a niche factory some 20 years ago. We had a tape robot with 8 tapes at some 200GB each. It'd do a full backup of everyone's home directories and mailboxes every week, and incremental backups nightly.

We'd keep the weekly backups on-site in a safe. Once a month I'd do a run to another plant one town over with a full backup.

I guess at most we'd need five tapes. If they still use it, and with modern tapes, it should scale nicely. Today's LTO-tapes are 18TB. Driving five tapes half an hour would give a nice bandwidth of 50GB/s. The bottleneck would be the write speed to tape at 400MB/s.
