What is the largest file transfer you have ever done?

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 think 16 terabytes? Might have been twelve. I was consolidating a bunch of old drives and data into a nas for a friend. He just didn’t have the time, between working and school and brought me all the hardware and said “go” lol.

I’ve done a 1PB sync between a pair of 8-node SAN clusters as one was being physically moved since it’d be faster to seed the data and start a delta sync rather than try to do it all over a 10Gb pipe. M

I transferred my entire NAS storage, which includes all of my backups, cloud files, my family’s backups, and my… Linux ISOs. That was about 12TB.

I did 100TB, 100 streams of 1TB, all simultaneous with rsync

I once deleted an 800 gb log file, does that count

I obviously downloaded a car after seeing that obnoxious anti-piracy ad.

I once robocopied 16tb of media

Professionally, Boeing near Seattle moves mind-boggling data. Personally,1500+ terabytes in a single 6 day jag, aboard a 29’ sailboat running off an inverter and 13 year old Dell hardware, completely off grid on anchor. It was a massive rescue operation, I did what I could with what I had where I was at.

I didn’t sleep well.

I’ll let you know… If it finishes.

I’ve migrated petabytes from one GPFS file system to another. More than once, in fact. I’ve also migrated about 600TB of data from D3 tape format to 9940.

I have to copy ~8 TiB of backup files twice a year.

Rsynced 4.2TB of data from one server to another but with multiple files

I’m currently in the process of transferring about 50 TB from one zpool to another (locally), so I can destroy and recreate it.

I’ve downloaded a few torrents that were around 5 TB each, they’re PS4 and Xbox 360 game collections.

Today I’ve migrated my data from my old zfs pool to a new bigger one, the rsync of 13.5TiB took roughly 18 hours. It’s slow spinning disks storage so that’s fine.

The second and third runs of the same rsync took like 5 seconds, blazing fast.

Local file transfer?

I cloned a 1TB+ system a couple of times.

As the Anaconda installer of Fedora Atomic is broken (yes, ironic) I have one system originally meant for tweaking as my “zygote” and just clone, resize, balance and rebase that for new systems.

Remote? 10GB MicroWin 11 LTSC IOT ISO, the least garbage that OS can get.

Also, some leaked stuff 50GB over Bittorrent
