Ooops..
Lustre is not a "computing system." It is s a filesystem. Still--data loss is data loss, even if it is only 77T. I've got working filesystems measured in petabytes.
We do perform incremental backups every night.
The team, with the University’s Information Department Information Infrastructure Division, Supercomputing, reported that files in the /LARGEO (on the DataDirect ExaScaler storage system) were lost during a system backup procedure.

A professional IT Dept should have multiple generations of backups. This article makes it sound like they keep a grand total of 1 backup. Doesn’t say much for the Information Infrastructure Division.
All your data are belong to us.
I’ve been doing system backups since the 1970s.
Always, always, always do test restores. Always.
Good thing they had their data backed up.
uhhh....

i still remember one of my roommates telling me the story that he couldnt get his ibm pc-at with the 100mb hard drive because the store guy would not sell him one - “no one will ever need a 100mb hard drive”, he said.
Discount count that one off the bat.
Frequent saving helps prevent file loss.
(Thanks Sim City)
I hear Pfizer is very interested on how well the excuse goes over....
I’ve been working in IT for decades and I have never backed up anything. Hahahahaaaa! Most of what people call data is useless.
Fret not, NSA probably has a copy somewhere.
I worked in computer sales decades ago. I could not imagine at the time how someone could ever fill up a 20 megabyte hard drive. One thing I have learned is that computer manufacturers and software writers will find a way to fill up all of the available storage space on the most advanced computer, no matter how large.
You only find you really need it when you don’t have it.
I was privy to one of the most catastrophic data losses ever. During a rather uninteresting database outage, a rogue Unix admin restored old data over new data, about 7 tbs, at a well know aircraft manufacturer. Totally corrupted the backups. The business was down for two weeks until we found an image that could be rolled forward with incremental backups. My contribution was saying, Greg don’t do it!
The root cause was that Greg had control over backups, disk allocation and Unix. There were no checks on his power. When I stepped into the breached I insisted that backups and disk were assigned to their proper groups. I took care of Unix.
Poor Greg died of a heart attack while still a fairly young man. He always wanted to be seen as the golden knight who rode in to save the damsel in distress. In reality, he was the worse lead Unix admin ever who became mad by root authority.
The acronym GIGO comes to mind: Garbage In, Garbage Out.
S’why you have to warm to the idea of absorbing the expense of a computer lab so your Admins can test their back-ups and confirm whether they work. Otherwise it’s like buying lifeboats for a ship and not bothering to test whether they float.
